Here is the final call for the 2008 NYD storm. It is basically perting out on all the models this afternoon and it looks like at least portions of SNE will prodominently see a rainstorm out of this one. Places like Boston to near Worcester, Plymouth, Providnce will all see mainly ain out of this one. Sorry, I wish I had better news for you guys. The boundry layer will just be too warm here for anything ore than a few sleet pellets mixed in with the moderate to heavy rainfall, that will be short-lived. Not drawn out like the NAM was showing us yesterday afternoon. There will still be snow with this system. If you travel to the hills of Worcester County and western Mass you will pick up between 2-4" of snowfall. SNH will see about the same as that as well. Here it will be a gloppy snow with temperatures 31-33 degrees. The areas that see rain will be more like 34-35 degrees, which will make all the difference. Upstairs, the temperature will be cold enough to support snow, it will be that last 1000-2000 feet that will turn things over to rain across the coastal plain. Central New England will do the best with this storm, picking up a quick hitting 4-7" of snow, with amounts dropping off as you go north, 1-3". In the end, this will be our last 'winter' storm for a while, as we will be going into an extended warming trend by this weekend, after a brief stint with Arctic air. Thursday, highs will be in the mid and upper teens.

In about a week, temperatures will be soaring into the 40's to perhaps the 50's and after about a 10 day stint of departures of +4 to +8 degrees, we will start to return to a wintertime pattern. BTW, Boston did not break the record. Only picked up 0.8" of snow from this past storm, bringing them to 27.7" for the month of December, just 0.3" shy of setting the new record.

Thats it for 2007, I will see you next year.

New Year's Day Storm First Call

Good morning. We are finishing up one bust of a storm and heading right into the forecasting of the next one. No looking back, right? Well, it will be really really close whether or not Boston gets the record right now, as it just changed to snow in the city about twenty minutes ago, but with temperatures around 34 degrees. It will be close. Most areas have picked up between 2-3" in Worcester County, and may pick up another one to perhaps two inches before it quickly ends before 8AM from SW to NE. That is where a spot 4" or 5" amount is possible. Closer to the city's suburbs, 1-2" is more likely. The city may come just shy of getting that 1.1" for the record. Down on the South Shore and Cape, sorry, you guys got all rain and will finish the storm with all rain and I can't say it looks much better for the next storm. Now after this all wraps up later this morning, the sun will break out of the clouds later today and this will shoot up temperatures to between 38-45 degrees this afternoon, so there will be melting and this is another reason why I am not optimistic of tomorrow's event being all that white in Boston proper.

For tomorrow, I think that from Boston points S&E, there will be mostly rain out of this next one. There could be a slushy inch of snow for places close to Boston, say up to Brockton and Milton, however, that would be about it. Once you get past Boston and especially past Route 128, an accumulation of 1-4" is possible. More if there is less mixing with rain, less if there is. You have to get out towards the Worcester Hills and western MA, southern NH to get into any significant snow. I am pretty confident that a good 5-9" of snowfall is possible here. NW of here, that is where the bonanza with this next storm will likely be. Snowfall amounts of 7-14" are possible, but if one model is right, we would have to cut QPF in half and in turn cut all these snowfall accumulations in half, so that is why I am not at all confident of this approaching storm system, coupled with the fact that I just busted BIG TIME with today's storm. Sorry about that. Did not expect to wake up to rain pounding my window 2-3AM.

I will have more on this forecast later and show if there is any warnings or advisories issued by the NWS later today.

Heavy Snow by Tomorrow Night

We have got ourselves busy the next several days with two storms that are going to affect New England. The first one is the one for tomorrow night and early Monday morning that will dump good snowfall for all of New England, a widespread 4-7" of snowfall, with a sweet spot along the Mass Pike from Springfield, to Worcester, to Boston and up towards the North Shore, encompassing Lowell and Portsmouth, NH. Here is where I think there will be local amounts of close to 8-9" of snowfall. This is not going to be real power from say Route 2 southward. It will be much more of the wetter type of spring snows wit the snow falling when temperatures are in the 30-33 degree range. That is what will prevent anyone from seeing over 10 inches of snowfall, coupled with the fact that this baby will be moving. Even the Cape will do fairly well with this storm system. I can see some mixing with rain down there, but I think it will be mainly a wet snow that falls there with 3-6" for southern RI and the Cape and Islands. I would say that Nantucket will see 1-3", but they are always a wild card and come closer to 6" or see a coating and switch to rain. Further north to the South Shore, including Hartford, Providence, to Quincy, a good 4-7" of snowfall will fall during the storm. Again, it will be a wet snow for the area here. Then you get into the pink sweet spot with close to 6"+ for many towns in here. It is still to be determined where this band of heavy snow growth sets up, but looking at the trends on the GFS and other computer models, it looks like this will be the area with the maximum snowfall. As I said 7-9" is possible in this spot. As you get farther removed from the storm, snowfall amounts will decrease, but snowfall amounts of up to 4-7" are still going to be common for much of CNE and NNE will still see a couple to several inches out of this storm as well.

Here is my city by city snowfall forecast....
Boston, MA 7"
Worcester, MA 7"
Springfield, MA 6"
Quincy, MA 5"
Providence, RI 5"
Hyannis, MA 4"
Plymouth, MA 5"
Hartford, CT 6"
Nashua, NH 6"
Gloucester, MA 8"
Keene, NH 7"
NEXT STORM DISCUSSION: We have to talk about the next storm now. I know that you probably don't want to here it, but once our first storm ends sometime around 11AM - 2PM on Monday, our next storm will be right on its heels and could be even larger than its predecessor. We will have about a 12-18 hour lull in the precipitation before the second storm's snow starts to move in from the S&W. At first, it looks like a measely clipper that would be moving right through our area dumping maybe 2-4" of snowfall in a short amount of time. However, on the past runs, the storm looks a tad more potent and now is starting to get a reflection of a secondary storm forming off the Mid Atlantic coast, which would mean oodles of more snow for all of New England. This has been showing on the models for the past two runs, more so on the 18z runs of the models and it looks like this thing has the potential to drop another 6"+ over our area on New Year's Day. Timing of this storm is still somewhat unknown, but I would say that if you are out until 5-7AM in the morning New Year's, Tuesday, you run yourself the risk of getting snowed in wherever you find yourself. This storm could have snowfall rates higher than its predecessor's 1-2"/hr, for it will be a dry fluffy snow falling into air that is in the 20's. We could potentially see snowfall rates in the extreme category of 2-4"/hr. I know its still some 66-84 hours away, but it is becoming more and more ominous with each run of the models. We will take it one storm at a time, but the potential is there for a biggie.
Interesting fact is that much of SNE has about 5-10" of snow already on the ground, so theoretically, many towns could have over 15-30" of snow ON THE GROUND by Wednesday! Wouldn't that be amazing. That is what will keep us very cold with the Arctic airmass coming down behind the clipper. We could be talking a subzero morning here Thursday with windy blowing snow and highs only in the upper 10's. We will moderate to around 40 by the end of next weekend, but the damage will have already been done.
Stay tuned to more forecasts and NOAA. I almost forgot to mention that all of SNE, except the South Shore and Cape are under Winter Storm Watches. I will post updates tomorrow of any warnings or adviories that go up for this first storm of this one-two punch!

First Guess on Dec 30-31 Nor'easter; Final Tomorrow PM

Here it is. My first guess for the upcoming Nor'easter that will help Boston smash its December snowfall record from 37 years. Talk about last minute. All the newest data came in around 6PM tonight and confirmed my thoughts that this will be a mainly snow event for much of southern New England, except the immediate South Coast of CT, RI and of course the Cape and Islands, where some mixing is always possible. I know it is a little early in time for putting out a map for this system, but I had to do it to give some reference point for what this storm could potentially do come Sunday night and into Monday morning. I don't think that this will be a blockbuster by any means, reason being is that the speed of this storm system will be like a rocket. It will shoot up the entire east coast in less than 24 hours. I don't think anyone will see more than 8-12 hours of accumulating snow from this storm system. However, the 8-12 hours that it does snow, it will be falling at the rates of 1-2"/hr. So, if you do the math, 6-12" for much of SNE looks like a good bet with this storm system. If it were to slow a bit as the EURO and UKMET are advertising, and we were to get extended accumulating snow than what the GFS is currently showing, some places will see some hefty snowfall totals from this one. A slower storm would give more time for the storm to gain some strength as well and that would means stronger winds and coupled with the fact that most of this storm will be in the 29-33 degree range, very marginal, the wet snow could cause power outages alone, but with wind, all bets are off. It could be a cold Monday morning in many peoples homes. So, as you can see there are still many many variables to be worked out for this storm system. I don't think areas from Boston points south and east are totally out of the woods regarding precipitation types, but I am pretty confident everyone away from the Canal will stay all snow with this event.

Next things we want to peg down with this storm will be...

1) Timing...when is this going to start. Right now it looks like Sunday night around midnight.

2) Duration....As I said before, looks like an 8-12 hour bout of heavy accumulating snows, longer duration would make all the difference.

3) much 'water' is going to fall from the sky.

4) Snow Ratios...right now I would say right around a 10:1 ratio, which is not a fluffy snow, but not glopping wet which would be 5:1 ratio.

5) Winds...strong winds coupled with heavy wet snow would result in power outages and some minor splashover.

6) Exact Track of LP...will as always make all the difference on who sees what type of precipitation. Looking right now like an all snow event away from South Coast and Cape.

7) Speed of LP...will determine the starting time and duration.

8) Monitor your Thermometer at Home...a temperature of 31 will make a world of difference compared to temperatures around 33-34 degrees for accumulations.

I will be back on tomorrow for any watches that will likely be issued by the NWS. Go out and buy some bread and milk. Oh yeah, don't forget to stock on the nachos for the big game tomorrow thats on every channel. Lay off the beandip though...just kidding. Anyway, bring an umbrella out with you tonight if your going to be out on the town past midnight. Rain is moving in.

Stormy Times Continue

Stormy weather dominates the headlines for much of the country as we head toward the new year of 2008. As we speak there is a good sized snowstorm dumping over a half foot of snow over Chicago and other parts of the Midwest. That storm will get here after midnight and be a warmer with maybe a brief burst of snow in southern NH that will even quickly change to plain rain there as temperatures warm into the mid and upper 30's. We will see the rain come down pretty heavy for a while with it all winding down sometime early on Saturday morning, before the sun starts to come back out in the afternoon. It won't be a flash freeze situation, temperatures will actually be quite mild, in the lower and middle 40's. It actually looks nice tomorrow afternoon. Then all eyes need to be put down to the Gulf States, namely New Orleans as we watch where our next storm will be coming from.

SUNDAY NIGHT/MONDAY MORNING STORM DISCUSSION: This storm has been on the models forever it seems, and all over the maps. Earlier this week, the GFS had this storm going weakly out to sea in a flat progressive pattern. Today, the GFS is right about ready to go gangbusters for much of the I-95 corridor from DC to Portland, ME. Everywhere from NYC northward to Boston on the latest 12z GFS run would be getting a fairly decent dump of snow on the order of 6"+. Mixing issues will always have to be watched down on the Cape. Sorry guys. But there is another reliable model, not very reliable lately, that takes the storm out to sea, but in the past several runs, it looks to be siding with the more amplified GFS, EURO, and UKMET, and JMA for that matter. That is pretty good agreement in my book.

My concerns with this storm system is that there is no blocking high pressure over SE Canada to stop this NW trend on the models. I see no reason why this won't keep going west, northwest on the next runs, by say 50 miles or more. There is nothing there to stop it. I don't think it will become on Appalachians runner, but if it wants to hug the coast more, then we will have precip type problems in southern New England, especially along the coast. However, with the models the way they are looking right now and the fact that we are heading inside 60 hours for this impending storm, I believe that much of SNE has a good shot at seeing some significant snows Sunday night and ending Monday early afternoon. I will be watching this like a hawk, I can tell you that.

Tonight's 00z and tomorrow's 12z runs will be HUGE as they will pretty much nail the final track of the storm system. Right now I like where we are sitting and am becoming increasingly confident that somewhere in SNE will see a fairly good dump (6"+) from this Nor'easter. I am almost certain that Boston will get that 1.1" to break the all-time snowiest December record of 1970 as well. Not etched in stone just yet, but I'm pretty confident. Maps will start to be posted later today, if not, tomorrow.

One thing is for sure. The skiing this weekend in the north country will be excellent with many resorts reporting the best ski conditions in many many years. Many areas up north picked up between 4-6" of snow yesterday and as we here in SNE get rained on tonight, they will be picking up some more powder. Many ski resorts in northern NH and ME will pick up between 4-8" of snow tonight from this storm system. Northern New England could do well with the storm come Sunday night as well, so you can imagine that the skiing will be excellent.

More on the storm tonight/tomorrow.

Another 'Wet' Storm Saturday

Today's snow threat seems to be whaning ATTM. The shield over western NY State looks to be too far north and heading in a NNE direction to give SNE any meaningful snows this afternoon. I still like my forecast from yesterday, I would just move all the snow boundries up north by say 50 miles. Boston will probably not break the record today. The last chance would be on Monday, New Year's Eve and there is an ocean storm threat, but at this point, it looks like it will stay mostly out to see. Our next storm comes tomorrow night into early Saturday morning, as a rainstorm. It may begin as a brief period of some mixed rain/sleet/snow far N&W of Boston and Worcester, but even there it should change to all rain. The snow will be confined to extreme northern Vermont and New Hampshire. Maine looks to do pretty good with this storm, especially from Bangor, points north. In these areas, Saturday's storm good potentially dump 6-12" of snowfall. That will freshen up the bases as today many ski areas in central VT, NH, and ME will see a general 3-6" snowfall with the LP in NY sweeping towards the coastline. Sunday brings slightly colder air, upper 30's, which is seasonable for the date, before we have that potential miss on Monday.

Right now I would say that there will be a few snow showers in the air for First Night, but I can claim to much more than that. Temperatures around midnight Tuesday will be very cold. Boston will likely see temperatures dipping into the middle 20's as areas outside of the city will quickly be falling through the upper 10's. This will yield a frigid and windy back to school Wednesday with temperatures in the morning in the single digits, while afternoon temperatures only struggle to hit 20 degrees. Thereafter, we will have a 3-4 day period of cold weather before the entire country east of the Rockies will start to warm up. We could see next week with highs in the 20's mainly, but going into the weekend and especially the next week, we could be seeing high temperatures pushing 55-60 degrees. The January Thaw. Its a long way out, so it will need to be watched.

Thats all for today.

One - Two Punch Thursday

We have got ourselves a wintery day on the way for tomorrow. A coastal low has developed off the tidewaters of North Carolina this morning and is gathering steam and heading NNE. High cloudiness is already streaming into SNE this afternoon from this storm system. It will still be a graze for SNE, but we really do not need to worry about this first part of wintery weather in SNE. Tomorrow morning will feature mainly rain from Route 495, points S&E. Boston will see mainly light to perhaps moderate rain tomorrow morning as the LP passes just south of Nantucket. This will result in heavier rain down in SE Mass and the South Coasts of RI and CT. Rainfall amounts up to one-half to one inch are possible in these areas. NW of Rt. 495 may feature some very light freezing rain or sleet as temperatures by tomorrow morning in these areas will be very borderline, with temperatures probably in the 30-32 degree range. Closer to Boston, temperatures will likely be more in the 33-34 degree range, keeping them rain...for the morning. Temperatures aloft should cool towards late morning and early afternoon ahead of the development of a 'Norlun' signature developing off of the morning coastal. This will develop a finger of snow from the LP dying over Upstate NY and the coastal moving away from the SE coast of Massachusetts. This will give much of SNE and up to NNE a good 6-8 hour period of light to moderate snow with a band of heavy snow probably developing somewhere from Portsmouth, NH to Conway, NH to Portland, ME

This is outlined in my map for snowfall in Part 2 of tomorrow's wintery weather. Where that band of heavy snow develops as always with 'Norlun' type setups, that is where the heaviest snowfall accumulations will be. Last week it setup from Portsmouth, NH to Boston, MA. Much of NE Mass and NH picked up 6-10" of snowfall, after having morning news outlets forecasting 1-2" Boston the morning of the event. So this will be a very changeable forecast. Right now, I think that is where the heavy snowfall will take place, but there will be a wide swath of light to moderate snowfall with this one for much of New England, unlike last week with some places seeing close to a foot and others some twenty miles away seeing coating. There will be a wide swath of 2-4", with locally 5" of snowfall with this one from north of the Mass Pike all the way into central VT and northern NH and central ME. Boston will be on the line, so a couple inches is possible in the city itself, which would be enough to break the December snowfall record of some 37 years. Down on the South Coast to the Cape, it will be cold enough for snow, but I think you will be removed from the heaviest of the precipitation, so you will see generally under one inch of snowfall. Extreme northern New England will be removed from the heaviest of precipitation as well so 1-2" for much of northern ME to under one inch along the Canadian border.

This is a very changeable forecast that will likely turn into a 'nowcast' type of event. Right now, I like my maps for this event up above, so expect a wintery ride home tomorrow because most of this snow will be falling in the 3PM - 8PM timeframe, just perfectly placed to ruin your drive home. I will have updates all day today and tomorrow with any advisories that get posted from the NWS. I could see some warnings being posted in SW Maine, but that is yet to be determined. Check in later.

Boston Poised to Break December Snowfall Record?

It has felt like springtime around these parts the past few days. Highs in the 40's and melting snow. Today was a beautiful day and it classified as a white Christmas even if it was some of the warmest weather we have seen in some time, since Thanksgiving. We have some more mild weather ahead, but we also have snow back in the forecast as well. First, lets talk about tomorrow. Tomorrow will be a day that starts off bright and nice, but cold, which will likely have some black ice on the roadways until say 10AM. So be aware of this. All black ice will quickly melt by noontime as temperatures will be surpassing 40 degrees on their way to highs in the mid to perhaps upper 40's. There will be a light breeze that will make the day feel all the more refreshing. Down on the South Shore and Cape you will notice some dark high clouds start to develop from the ocean as an ocean storm will ever so closely come right up against us without getting us into the action.

POSSIBLE THURSDAY STORM DISCUSSION: That said, there will be a period of light to moderate rain on the South Shore and Cape, with perhaps a rain/snow mix all the way up to Boston, Worcester, and possibly up to say Lowell. This would not accumulate, but we will turn our eyes out towards western New York State at this time to see a band of snow with a seperate system advancing towards New England. Both of these storms will start to 'link' up right over southern and central New England, which will cause snow to develop for much of New England at this time, with perhaps a mixture of rain and snow down on the South Shore and Cape Cod. North of the Pike, Thursday evening and night, perhaps right around the evening rush, the snow will pick up in intensity and start to accumulate. Right now it looks like south-central Vermont and New Hampshire through Maine look to do the best with this storm system, but those accumulating snows could very well make it down to Boston. As you probably know, Boston only needs 1.1" to break the old record set in 1970 for December snowfall, the record being 27.9". Boston currently sits at 26.9", just one inch off the record books. I am not sold on accumulating snow just yet as the usual case is that one model shows nothing while the other gives us a bit of accumulating snow on the tune of a couple inches. Such differences, only 24-48 hours out! So, I will hold off on making any maps just yet. I may make one tomorrow morning/afternoon, as more data comes in. It will be interesting to see how this pans out.

VERY PRELIMINARY CALL: If I had to make a guess at this time. I would say maybe a coating from northern CT/RI along the Mass border. Nothing South Coast and Cape. Along the Pike into Boston up to Route 2, I would go with a light, but sloppy, 1-2" of snow. North of Route 2 into southern-central VT and NH through southern ME, 2-5" of snow is possible. These numbers will most certainly have to be fine tuned tomorrow, and especially tomorrow night as the final data comes in.

This storm will have lots of surprises, so expect the forecast to change. Thereafter, a warm rainstorm is slated for Saturday before we cool off again going into the New Year.

The December Thaw

We are in the middle of our December Thaw right now. Snowpack across SNE has taken a big blow the past couple of days. Two days ago, much of SNE had a healthy 10-20"+ snowpack, today much of SNE is generally under 10". We are only going to continue to lose our early impressive snowpack. More mild times are ahead for SNE. This afternoon will make it into the mid and upper 40's. Tomorrow will be much of the same with mostly sunny skies and highs in the middle 40's. Lows will struggle to get below freezing tomorrow night so there will be extended melting going on and this will propell us into a warm Wednesday, return day Wednesday with highs getting back to around 50 degrees. I have been watching a storm system for the past couple of days for Thursday and it looks like it could now get close enough to our area o see some rain on the southeast coast of Massachusetts and Rhode Island.

Thereafter, it looks like we could cool and we could see some light snow sometime later next weekend. That is way far out I won't even go into it. More tomorrow and enjoy your Christmas Eve.

Heavy Rains Raise Flooding Worries Sunday

Sorry I haven't posted in a while. Thursday's storm system was quite the snow producer for eastern New England. Many areas in eastern MA and NH and ME saw between 6-10" of snowfall. Boston picked up over seven inches of snowfall, putting their December snowfall stats up to 26.9" for the month. Now with snowpacks of 10-20" across southern New England, tomorrow raises my worries for street and basement flooding. The roads have shrunk, clogging many drains with ice and snow. This will be bad with rapid snow melt tomorrow and heavy rains, on the order of one-half to one inch of rainfall. This will add to the 2-3" of liquid equivalency in our snowpack right now for a grand total of 4", on our roofs. It could be a bad day tomorrow for collapsing roofs. Thereafter, we will cool down, but not to the levels where we have been the entire month. Maybe upper 30's to around 40. Nothing too cold. Next storm threat comes Thursday, but that looks to be mostly out to sea. It will be watched nonetheless. Enjoy your last minute shopping today.

More Snow

We have got ourselves another snowfall on the way for eastern New England. A clipper is coming out of the Great Lakes tonight and tomorrow and once it hits the Atlantic it is going to explode and throw an inverted "Norlun" type trough into eastern New England. These events are very finicky and change during the actual event. That said, it looks like much of SNE will at least see some snow. The further SE and SW you live, you may see it start as rain and stay as a wet snow for the event with temperatures hovering around 32, but everyone else should cool enough to see mostly snow out of this event. Many people will have to break out the shovels for this one again and people in northeastern Mass and up onto the Seacoast of NH, you may need the plows out again. There we could see 3-6" of snowfall. There will be a spot somewhere between extreme SW coastal Maine through the Seacoast of NH and northeastern Mass that could see over six inches of snowfall. Where this band of heavy snowfall sets up will make all the difference. Either way, I think much of eastern Mass could see a general 2-3" overall. This will mainly occur late tomorrow night and into the day Thursday. Thursday could be a day that features on and off snow showers or 'snizzle' throughout the day, giving the wintery look. A few delays will be possible in Middlesex and Essex counties.

I want to stress that this is an ever evolving storm system and it will need to be watched through tonight through tomorrow and through the actual event to see where exactly this heavy band of snow decides to set up. Someone in eastern New England will wind up with up to 8" from this...where that is, is too hard to pin point at this time. Stay tuned.

Finally a Reprieve!

Last week was one of those rare jam packed weeks with every night something new was happening, whether it be rain/ice/snow. Thursday many areas across SNE picked up between 8-12" of snowfall. Today many areas picked up 7-11" of snowfall, making a four day total of 15-23" of snowfall. The snowbanks are pretty much unreal right now where I live. Boston has seen 19" of snow so far, couple with the 1.3" it saw on December 2-3, Boston is now over 20" of snow for the month of December. It kind of snuck up on us. I am already over 24" for the season so far! And winter hasn't even started. This week looks to be much quieter than last week, but cold nonetheless. The snow will not be going anywhere soon. I've got an 18" snowpack right now with a glaze of ice. Its amazing out there. Tomorrow will be a cold and windy day with wind chills in the teens all day. We try to warm up this week, but we will likely not budge 32 degrees until next weekend, with a storm JUST missing us to the south on Friday. That will need to be watched. It doesn't look like a major deal at this point in time right now. Maybe some snow for the Philadelphia and New York City areas. I think we can share. I think we will get that white Christmas, but lets not bank on it just yet!

Winter Storm Warnings and Advisories for Much of New England

I will be the first to tell you that this storm is killing me. I don't know what to expect. This setup should send us a mostly rainstorm, but that is not what the models are showing. In fact, temperatures just outside of Boston may never get up over 32 degrees. This Arctic air that moved in early this morning means business. My high today was 21 degrees. Right now, I'm sitting at 16. This cold air is really going to help us in regards to snow. Once the precipitation starts, evaporational cooling will take effect and everyone will start as an initial burst of heavy snow. By 3AM the snow should start here in eastern New England and by 5-7AM the snow will be falling heavily. Snowfall rates early Sunday will be on the order of 1-2"/hr. This will allow the Cape and Islands to maybe see that 1-2" on the first hour of snow. Winter weather advisories are up for the entire state south of the Pike, including Boston and the coastline for a general 2-5" near Boston to 1-3" south. North of the Pike, a winter storm warning is in effect for a general 4-8". The mountains will do well with over a foot.

I pushed the snow lines further SE from my earlier thinking. It will now be going into nowcasting mode and watching observations. It will be a tough forecast. Lets get through this one and then next week will be much more quiet. Beware of the flash freeze tomorrow night. Whatever slush is on your driveway tomorrow night will be there for quite a while.

Updates tomorrow with observations and radars. Its going to be a wild ride. Oh yeah, winds up to 60mph tomorrow afternoon with heavy wet snow could lead to power outages north of the Pike. Keep that in mind. Have your generator on standby for the 1PM kickoff of the Pats and Jets.

Tough Forecast; Making Final Call

This storm does not look as good as say it did last night. We have been banking on a front end dump from this storm and I just don't think we are going to do it. I believe the Cape starts off as mostly rain with a few sleet pellets mixed in. Then it will change to all rain even up to say Hull and Quincy before the storm even gets started. Boston may get an hour or two of snow, but quickly change to sleet and rain within hours of starting. Snow accumulations in Boston look to be around an inch. The pink area has a chance of seeing anywhere between 1-3" snow followed by a period of sleet and freezing rain. I don't think freezing rain will be a big deal from this storm. Sleet will be the primary form of ice here with this storm. I pushed back the 3-6" swath much further west. Here, a change to sleet is even possible for a duration of the storm, cutting down on amounts. Once you get way out past Rutland, VT, will see over 6" of snow with perhaps over a foot in northern New England.

I will do my city by city forecast for this storm....

Providence..........Less than 1"
Hartford...............Around 1"
Boston...................Around 1"
Nashua, NH..........3-4"
Keene, NH............4-5"

I will post any advisories or warnings that should go up today by the NWS.

First Guess on Nor'easter

Here is my best guess for the weekend storm today. I do believe that all of SNE will experience some snowfall this weekend. Even down on the Cape and Islands. Everyone will start this storm as a quick burst of heavy snow. It will put down a quick 1-3" before the changeover for everyone, more NW. Then the Cape and South Coast will start to change over to all rain and sleet further NW towards Quincy and coastal locations. Temperatures will likely come up to the low 40's on the SE portion of Massachusetts early Sunday morning before the big flash freeze. Further NW including Worcester, Hartford, and Boston's immediate NW suburbs, there will be a longer period of snow, followed by more sleet and then plain rain even here. All said and done a quick 3-6" of snowfall will accumulate. As you continue to head NW, the snow will quickly increase to 6-12" in southern NH and northern Worcester County. Here a mix with if not total change to sleet/rain is possible too. You will have to head into Upstate NY, VT, northern NH and ME to see all snow. Here the possiblilty exists for a healthy 12-20" of snowfall. This storm reminds me of the Valentine's Day snowstorm of last year. It will be a similar setup. Boston got about 2" from that one, but nearby suburbs quickly picked up 6" of snowfall. We will have to wait until tomorrow to see how strong the cold is associated with the Arctic front.

Warning...if this storm tracks a little farter SE, push that 6-12" into Boston. It it travels a little farther NW, then we will see mainly rain here in eastern New England. Right now, I like the track where it is. The GFS has been extremely consistent in this track for a couple days now and I feel this is the best forecast right now.

Update tonight or tomorrow if any watches or warnings are to be posted by the NWS.

Quick Hitting Winter Storm on the Way

6PM UPDATE: The new models have come in and it looks like this storm for tomorrow is going to be a tad slower in leaving and a bit 'wetter' in regards to QPF amounts. I have really upgraded snowfall amounts for tomorrow. GFS and NAM have pretty much gone gangbusters with this storm for tomorrow and NAM actually paints up to 16" of snow for Providence tomorrow, while Boston gets between 10-12". GFS has a wide strip of about 12" of snow across SNE. Even the Cape now looks to be all snow with this event. Hyannis has just as much if not more of a chance of seeing a foot of snow from tomorrow night's storm as Boston. Heavy snow warnings are up south of the Pike right now with winter storm watches in effect north of the Pike into southern New Hampshire. Heavy snow warnings will be soon issued for north of the Pike and it is going to be a doozy tomorrow. Widespread delays and cancellations on Friday.

Timeline....Snow starts from west to east from noon to 3PM. It will end sometime before midnight now. It will be an amazing storm with the peak of the storm during the evening commute with snowfall rates of about 2-4"/hr. That strip near Hartford/Providence/Plymouth to Brockton to get that 12"+.

It's going to be a mess. Stay tuned for later forecasts.

1PM UPDATE: Our first major winter storm of the 2007-2008 season is upon us here in SNE. We have a quick hitting winter storm on the way for tomorrow. You wouldn't know that a big snowstorm was on its way to SNE if you stepped outside today. Temperatures are all the way into the mid 50's down on the southeastern part of the state. Even I am flirting with around 50 degrees this afternoon, whith much of the snowcover vanished with a gusty wind. However, a cold front is in the wings and will drop temperatures into the upper teens and low 20's come morning to set the stage for our first significant snowstorm of the season. This storm will just be an appetizer for what could become a blockbuster of a storm Sunday. I'll tell you, this is what I live for! The models have been going back and forth regarding tomorrow's storm system, but one model hung tough the entire time and never wavered. For weather enthusiasts like myself, we should all give the GFS a round of applause. NAM crapped the bed, but now it is on board with the big storm for tomorrow.

So first of all, winter storm watches and heavy snow warnings are already in effect down in CT and RI...I would expect watches/warnings to make it up to all of Massachusetts and southern NH, except the seacoast of NH, as they will probably get an advisory from their NWS. The rest of SNE will likely get a heavy snow warning/winter storm warning from Taunton NWS.

The timing of this storm is very compact. We will likely see snow break out sometime after dark tomorrow night, say around 7-10PM. It will quickly become heavy. In fact, we will only have a SIX TO EIGHT HOUR period of accumulating snow. You can imagine with the snowfall totals I am forecasting...snowfall rates could approach 1-3"/hr. Visibilities will come under 1/4 mile overnight Thursday, so be careful if you have to be out late. Snow will wrap up before say 5-7AM on Friday morning and I believe most school districts, especially south of Route 2 will be closed. Delays north of there. So enjoy the warmth now and we will take it one storm at a time. As you are shoveling and snowblowing Friday, I will talk about the storm that will probably bring more heavy snow into all of New England come Saturday afternoon and night. Better yet, just wait until Sunday night to shovel.

We've got a busy few days ahead. Enjoy!

TWO Storms Watching...Thu PM and Weekend; Updates Soon

I am sure everyone has been hearing about the possible storm here on Thursday, only leading up to the bigger potential 'blockbuster' event here later this weekend. This could be a doozy. I am hesistent in putting out any maps for the Thursday night storm because there is such a large discrepancy in the models at this point. One model gives all of SNE several inches of fluffy snow, while the other barely brings flurries to Providence.

I will put out a call for the Thursday event tomorrow, sorry for being really close to the event, but there is too much room for error right now to make a prediction. It could go either way at this point.

Any maps/discussion of the potential weekend storm will have to wait until this first storm is safely behind us on Friday. A nice warmup.

FINAL CALL...Dec 9-10 Snowstorm

9PM UPDATE: I am making my final snowfall forecast for the storm system coming through tomorrow night and early Monday morning. This will be no means be a blockbuster or even major storm, but it will be a good storm to mess up tomorrow night's plans and morning commutes on Monday. I have generally made the 2-4" range a bit bigger, encompassing much of SNE north of the Pike. Further north of here into southern NH, is where I would expect the jackpot with this storm. Here I can envision 4-6" of snow coming down before we even talk about a mixture with sleet before it ends very early Monday morning. Boston will get an inch or two before a mix with sleet and freezing rain, but areas in the pink, especially away from the southern coast of the South Shore will stay below freezing through the storm. Its just the fact that the upper levels where the snowflakes form will warm just enough for a change from snow to sleet midway through. The Cape will be above freezing through most of the storm.

Winter Storm Watches have been posted for interior SNE, south of I-90 this afternoon for ice accretions of 0.3" to 0.5"+, which would cause havoc on the power lines and trees. Widespread power outages would be possible. This may either go to a warning (winter or ice storm) or advisory tomorrow and north of the Pike will see a winter weather advisory go up, if not a Winter Storm Warning in southern New Hampshire. I will have more on this forecast tomorrow.

Snowfall/Ice for a few selected cities....

Providence, RI....2" (to sleet/ice)
Harford, CT....1" (to freezing rain)
Boston, MA....2" (to sleet/rain)
Worcester, MA....2.5" (to sleet)
Fitchburg, MA....4" (some sleet mixes in at end)
Burlington, MA....3.5" (sleet mixes in around conclusion)
Lowell, MA....5"
Nashua, NH....5"
Keene, NH....5"
Springfield, MA....2" (to sleet/freezing rain)
Cape Cod....Mainly rain

Thats all for tonight. More tomorrow.

Wintery Mix: December 9-10

Here is my first and probably final call for the storm system moving in tomorrow afternoon and evening. The precip will move in from west to east and will probably start as snow for everyone, but quickly transition to rain/mix on the Cape and South Coast. Further north of there, in the pink shaded region, there will be more of a mixture of snow/sleet, but freezing rain will be the big player here with over a 1/4" ice accretion possible. I would not at all be surprised to see Winter Storm Watches hoisted for this region later on for the ice. More likely Winter Weather Advisories by tomorrow morning, though, for a majority of SNE. In the pink region, there is the chance of about 1" of snow before the flip to freezing rain. Here, by the Monday morning AM commute, temperatures may come up above 32, but that may be pushing it as many mets believe that the GFS and NAM are overplaying the warm air and that the cold will be much more stubborn to let go. In the blue region, we will see more snow from this before we think about a changeover. A solid 1-3" of snowfall is possible, maybe more if this area can stay mainly a snow event. Where it does stay mainly snow, mainly north of the Pike and away from Rt. 128 and the coast, 2-4" is likely with some spots in northern Worcester County maybe getting closer to 5-6", tops.

There is a wide model discrepancy between the NAM and GFS this afternoon, however. GFS paints lots of snow, north of the Pike and a good amount south, but the NAM doesn't give anyone in SNE more than an inch or two, so you can see this is a high stakes, low confidence forecast. A forecast that will likely change. I played it in the middle. Either way, the Monday AM commute is going to be messy with more delays and cancellations likely again.

More on this forecast tomorrow with any advisories, watches, or warnings underway.

Unsettled Wintery Weather Week Ahead

We have had a very wintery week this week. We had a nice 2-6" snow/sleet storm Sunday into Monday and today we had a surprise 0.5" to 1" of snow across the area. Tomorrow will be the one "mild" day with temperatures actually getting back to normal. That is why it is snowing tonight. This snow is actually the warm air riding over the cold air, producing some snowfall. A cold front will move through tomorrow and we will be back in the cold on Sunday with a package of moisture coming at us from the Ohio Valley. Snow will develop from west to east during the afternoon and evening and reach the coastline, Boston, by dinnertime. The snow will likely falling light to moderately overnight and may mix with some sleet/ice/rain from Boston south and east. Accumulations will be light, won't go into figures, but a couple inches are not out of the question. We will see a lull in the precipitation on Monday night through most of Tuesday before another batch of wintery mess moves through the area on Tuesday night. Too early to see what type of precipitation it will be. We warm up a tad on Wednesday, mid and upper 30's, perhaps 40's on the Cape. Clouds will thicken Thursday with colder air to setup the next storm Friday. A crazy week is ahead of us...there will be many delays and cancellations next week. Lots of work will be getting done.

Storm Misses South Tonight; Another in our Future?

Wow, we really missed out on a very potent clipper system today that dumped a good stripe of 3-6" from Minnesota to right off the Mid Atlantic coastline. Some areas near Chicago and Milwaukee, WI came in closer to 6-10" with this clipper system. Preliminary reports show that even Washington DC came in with about 3" of snowfall today. Well, that missed and our eyes move to our next chance of some snowfall and that would be on Friday afternoon, mainly during the overnight hours. First, we have got to get there. Tomorrow will be more of the same, another brutally cold day for early December. Temepratures will likely stay in the upper 20's to around 30 degrees tomorrow across SNE. Early morning lows will likely range from the upper single digits to upper teens in the cities tonight. Then Friday, the clouds will increase during the afternoon and we will likely see some light snow commence sometime after dark Friday night. The snow will start from west to east, but as it hits the coast near the Cape, the storm will intensify rapidly and this could enhance the precipitation over southeasten Massachusetts. The unfortunate fact here is that this area may be just a bit too warm for a pure snow event. There will likely be some mixing with rain, especially down on the Cape. Closer to Boston, there could be a period of some light snow and flurries, with all of this collapsing SE as the main storm gets going over the ocean, robbing our moisture.

That will move out and modify temperatures for this weekend. We may even get closer to normal on Saturday with highs getting back into the low 40's, perhaps. The normal high for this date is about 44 degrees, so a couple degrees below normal will feel mild compared to what we have been going through. We cool a bit on Sunday and then we get into a messy storm situation for early next week. There will be multiple ripples of low pressure along a nationwide frontal system that will need to be watched. The cold air will be just to our north and if any one storm can tap into it, we could be talking of a snowstorm around these parts, but for now, I will play it conservative and say that it will stay mostly wet than white. Any snow would be confined to ski country, where they will take all they can get.

More on that complex early week weather situation tomorrow, even more likely this weekend, after discussing our possible light snow for Friday night. No need to post accumulation maps, but just keep it in the back of your mind if you have dinner plans Friday night and see a little festive snowfall, just to remind us that there are under 20 shopping days left.

Late Week Snows?

Cold Weather Supreme

We are not going to warm up in the near future. We are going to stay very cold through the period with highs struggling to get above freezing through Sunday! Just for reference, the average high for this date is 45 degrees. This will be good for climo as our average highs for December will start off very low in the well below average category. The next system will move in on Friday with a few flurries. That may continue into early Saturday, but at this point, it does not look a lot more than a few flurries. Then we will stay cold on Saturday and Sunday with highs in the 20's. A storm will try and move to our west later on Sunday, maybe allowing for a mixture of precipitation moving into southern New England, a setup similar to this past weekend. We will need to watch it.

FINAL CALL: Dec. 2-3 Snowstorm

This is my final call for the storm coming into our area tonight. The first snowbands are coming into my area now. I upgraded the totals a bit from yesterday afternoon, due to the fact that the storm has been colder than the models have been showing across the country and that today only made it to 24-27 degrees, when yesterday forecasts where calling for 30-35 degrees. Secondly, the NAM went colder for north of the Pike and has this area in mostly snow now. It has had three straight runs of making it colder. Thats it.

Cape Cod sees some snow showers tonight and will see a dusting to rain, all will wash away.

The pink area includes Hartford, Providence, and immediate Boston. Here we will see a longer period of snowfall, changing over around daybreak. Before that 1-3" may fall and before the flip to rain we will see a period of sleet or freezing rain.

The light blue area includes Worcester, Bedford, to Lowell and Lawrence. Here the snow will last longer, before a switch to sleet or freezing rain. Plain rain will not even likely make it to this area. 3-6" is likely here.

Northern New England gets the bonanza with this storm. Southern New Hampshire gets a solid 6-12 inches, while the ski resorts get a solid 12-18"+ of fluffy white gold. There will no doubt be packed powder conditions up there all this week.

Next chance of snow comes Thursday.

First Significant Snowstorm for New England

8PM UPDATE - Winter Storm Watches have been issued for much of New England this evening, except eastern Massachusetts, including Middlesex, Essex, Suffolk, Norfolk, Plymouth, Bristol Counties. I believe that by tomorrow morning a Winter Weather Advisory will at least be issued for Middlesex and Essex, but Suffolk, Norfolk may be on the line. I really have no changes from the 1PM update. Storm looks to be on course for a good 1-3" snowfall around the Boston metro area. Snowfall amounts may be a tad heavier out towards Lowell and Worcester, where maybe more like a 3-5", isolated 6" amount is possible. School closings...I would say tonight that the best chance of school closings will be north of Route 2, outside of Route 128 and especially 495. Southern New Hampshire still looks to be getting a good 6-12" snowstorm out of this...which means I may have to play around with those numbers a little bit. I will wait and see the 00z model runs tonight and then issue any changes late late tonight or tomorrow morning. More later.

1PM UPDATE - My snowfall forecast from this morning had to be thrown out. NWS out of Taunton is downplaying this storm system greatly with their 12:15PM Update. They are saying it is going to be hard to get over 1-2" of snow inside Route 495 with this storm and what does fall will be washed away. I have stuck by the models that were showing mostly snow for areas north of the Mass Pike, but the 12z GFS came out and has the rain/snow line all the way into southern VT and NH. The NAM still has that rain/snow line south of the Pike, but I have seen the NAM lag in this department and is overdoing the cold air, as usual. That rain/snow line will probably make it as far north as Nashua or Manchester, NH at the height of the storm, but the sleet will be the major factor that limits snowfall accumulation in SNE. For when it would be cold enough to support all snow even into Boston, the upper layers will warm enough to produce a sleet storm. Unfortunately, that is how it is looking now. I'm going to stick by this map until I see new data either bringing in more warm air or cold air. Yesterday the trend was for colder and colder, but today the trend has been in the other direction. Warmer and warmer. I wouldn't be surprised if I had to lower these snowfall accumulations for SNE.

South Shore, Cape, South Coast.........Brief mix to rain
Central CT to inside Route 128.......Mix to mainly rain; maybe an inch
Outside 128 through Worcester County....Snow to Sleet; 1-3"
Southern NH and VT.......Mainly Snow to some Sleet; 4-8"
Ski Country in VT, NH, and ME......Heavy Snow; 8-16"

All areas may end as snow on Monday afternoon, but accumultions would be limited as there is not much moisture after noontime Monday. This one just didn't pan out for SNE.

Winter Storm on the Way!

We have got ourselves an old fashioned New England winter storm on the way to end this weekend. We will expect the snow to develop for all of New England during the afternoon Sunday. It will spread into our area from southwest to northeast and quickly become moderate to heavy, especially north of the Pike. I made this map as a first outlook for what I am expecting for all of New England. I haven't put numbers to these yet, just categorized them. We will start with extreme southern New England, down on the South Coast and Cape. Here we will start as a very brief period of moderate snow that will eventually mix with sleet and then change to rain as temperatures should come up to the mid and upper 30's within a few hours of a ESE wind. There is a possiblility of at least seeing a coating to slushy inch of snowfall in this area. The pink shading is the variable and question mark. Here, if the GFS is correct, we will see more mixing with sleet/rain, but if the NAM is correct, we will only see a brief period of mixing, and a mainly snow event. If I had to put numbers to the pink area, I would say that conservatively 2-4" of snow is likely, including the city of Boston itself. Just N&W of the city, snowfall amounts will increase dramatically. Just 5 miles NW, say in Medford to Newton, we will see a mainly snow event with snowfall amounts in the blue up to southern New Hampshire and southern Vermont ranging from about 6" in Newton to 10-12" in Keene, NH. The blue area for all of New England is where a general 6-12" of snow will fall. More like 5-8" if you want to get more specific inside of Route 495 and especially 128. Then we get into central NH, VT, and ME. This is where temperatures will be in the upper teens throughout the event with heavy snows and gusty winds in excess of 30mph. There is the possiblility of seeing near blizzard conditions at this time. Snowfall, especially in ME, could be very heavy. We could easily see snowfall amounts of 12-24" in the red area. Some places like Sunday River and other ski resorts interior ME could see between 24-36" of snowfall, a dry fluffy snowfall. This is no joke. This will be a major storm that you will need to follow every step of the way until it starts because things are not set in stone just yet.

I will post a more detailed snowfall map with numbers sometime tonight or tomorrow.

Thursday Clipper...Ski Country Snows

Ski country will be getting some white gold tomorrow as the clipper system that has been on the maps for several days moves into our area. Don't worry about snow for southern New England. It will be just too warm here in southern New England. Highs tomorrow will rebound to around 45 to 50 degrees in southern New England, while much of northern New England will stay in the 30's. Snow will break out during the day tomorrow from west to east and then could come down moderately in northwestern Maine, with accumulations in the dark blue area of around 2-4", with isolated higher amounts of up to 6" possible. Especially in ski resorts. Other than the 2-4" in NW Maine, much of the rest of northern New England will see a general slushy inch or two of snowfall, with a thin sliver of mixed precipitation. Further south, as mentioned, it will be all rain with mild temperatures before we really cool down on Friday through Sunday. Highs on Friday will be in the mid 30's. Highs on Saturday will be in the upper 20's with the risk of an afternoon flurry and then Sunday will be in the low 30's with snow developing from SW to NE, quickly changing to sleet and then rain from Hartford to Providence to Boston.

It is still way out there, but preliminarily, I would say that areas south of the Pike and along the immediate coast may see a slushy coating on the onset with that quickly being washed away with temperatures rising into the 40's and maybe some 50's on the South Coast on Monday. North of the Pike, generally NW of Rt. 128 and especially Rt. 495, there may be a slushy inch or two of snowfall and snowfall amounts will quickly increase to about 3-6" through southern Vermont and southwest New Hampshire with some parts of northern New England likely seeing over 6" of snowfall Monday.

It's still a wait and see situation, so stay tuned to later changing forecasts. After the storm, very cold weather will pour into New England with highs likely 25 to 35 degrees on Tuesday across the six state region.

Back to Cold then Warm then Cold

Our seesaw ride continues. After having highs in the low and middle 60's this morning with the sun shining around sunrise, feeling like a mid July morning, the cold air has ushered back into southern New England. Tomorrow will be a seasonably cold day with highs generally in the low 40's. Then a warm front will move back through the area and we will warm up ahead of a few showers on Thursday with the rain showers being snow showers up in northern New England, mainly Maine, where a couple inches of snowfall can be expected. After the clipper event on Thursday we go back into the deep freeze with temperatures going into the 30's on Friday and then likely stuck in the upper 20's to low 30's on Saturday, despite the abundant sunshine.

Then comes the storm threat for the end of the weekend and Monday. Yesterday and as early as this morning, it looked like we were going to see our first significant snowstorm of the season, but the models have since changed and most it not all of calling for a Lakes Cutter, so that warm air will surge into SNE on a southerly gale and warm us up enough to see plain rain. Ahead of the warm front, we may start as a brief initial period of rain/snow/sleet, but that would quickly transition to rainfall, especially near the coasts. If you want to see all snow, you would have to travel to the far reaches of Northern New England, and even there, a wintry mix cannot be ruled out. Some models go as far as to bring temperatures up into the 50's and 60's again with showery rains into areas of southern New England on Monday, similar to today, especially south of the Mass Pike.

Basically, if you were hoping for a snowstorm to end the weekend, our chances of seeing significant snow are dwindling and FAST!

Rainy Back to Work Monday

What is better to start off the new work week seeing rain and clouds, to define our depressed feeling of being back at work and school, with no hope of a vacation until late December. Oh well, we needed the rain all summer and we are finally getting it. Tomorrow will be a very rainy day with the rain coming into eastern Southern New England likely after the morning commute. It will become heavy in the afternoon and continue much of the evening and overnight hours, likely ending as showers during the morning commute on Tuesday, after say 8AM. All said and done, we are seeing a beneficial 3/4" to 1.25"of rainfall out of this entire event. Worcester County (northern) is under a Freezing Rain Advisory right now for fear that if this starts early enough tomorrow morning when temperatures are just around 30-32 degrees, there may be some freezing rain. Closer to the coast, by the time the rain moves into our area, the temperatures will have risen out of the freezing range and up to the mid and upper 30's. No threat of frozen precipitation here.

Once it does clear up on early Tuesday we will be talking about a warm afternoon with gradual clearing. Highs will be in the mid 50's and the smell of spring will be upon us once again after leaving on Thanksgiving Day. It will be short-lived, though, with the cold really coming back after seasonable temperatures Wednesday through Friday, mainly in the 40's.

By the start of the weekend, we will be in the low 30's with all eyes turning southwest, looking for our next storm coming with a renewed source of cold air for New England. We will have to wait and see how this eventually pans out for the first of December, with the NAO crashing by this time period. It could get interesting...

Return to Cold, For a Little While

Today was absolutely amazing. The warmth was amazing. The fog last night and early this moring Pike north was wicked thick and soupy. Once that moved to the north, the sun broke out and the temperatures soared to give us a fantastic Thanksgiving. The Macy's Thanksgiving Day Parade was done this morning with temperatures around 65 degrees! It felt more like a Memorial Day Parade. Temperatures down on the South Shore into Providence were amazingly warm as well. Providence hit a high of 67 degrees with Norwood coming in at 66 degrees. I should have stuck with my forecast from a few days ago. Here where I live, I hit 59 degrees and have since seen the winds shift to North and the temperature has dropped about 10 degrees in the matter of an hour and a half and still falling.

This will usher in the cold and an end to the extreme warmth at least until the next storm system moves in for the early to middle part of next week. First tomorrow will be a much colder and windier day with highs only managing mid to upper 30's. It will feel more like late December, early January out there. Overnight lows will really plummet on Friday night. Low in the suburbs will come down to between 10-15 degrees. The cities will hold onto the warmth a bit longer, with lows coming down to between 25-30 degrees, in Boston. Providence/Hartford will fall to 20-25 degrees.

Then we will start to warm up ahead to the next storm and then we will be talking about a warm windswept rain for Tuesday through the day, likely tapering later in the afternoon with temperatures dropping later. Then we will be back to the cold and wind for Wednesday.

Any snow in the forecast? I don't see it right now. It looks to be dry this weekend when we would have cold enough temperatures to produce snowfall, but once we get some precipitation the temperatures will warm enough for us to see all rain on Monday night into Tuesday.

Thereafter, its too far to know for sure what will happen. These computer models are bad enough going 3-4 days out.

Coldest Air of the Season

First, before we get to that we have to get through the raw conditions on the busiest travel day of the year and a very warm and unsettled Thanksgiving Day. Thereafter, we will be able to talk about some cold weather this long holiday weekend and see how our Black Friday forecast will be. One thing I am watching now is that this cold air will not bring a snowstorm to southern New England. It looks that as we head towards our next storm system, we will warm up just in time for this to be a mostly rain situation because all computer models have been consistent in keeping this storm staying west of the Appalachian Mountains. If we get on the southern side of the warm front, we will warm up into the 50's and have showery rains. If not, we will stay with a more steady rain and temperatures in the low-mid 40's in the valleys and northern areas of SNE, while Boston may stay in the upper 40's for highs. This is a week away, so the details about this forecast will be ironed out later.

Tomorrow will be mainly dry for all the football games in the morning for 10AM kickoffs. We should be very mild with temperatures in the 50's at this time. The rain will not move in until later in the afternoon. Once the rain moves in, plummeting temperatures will not be too far behind. By midnight, temperatures will already be falling through the 40's and be in the mid 30's outside of Boston.


8AM Tailgating.......Cloudy & Warm; Around 50

10AM Kickoff..........Cloudy/Chance of Shower; Low 50's

2PM Turkey Dinner............Chance of Shower; Low to Middle 50's

6PM Nap...............Showers Likely; Upper 40's

12AM Late Night Parties.......Showers; Upper 30's


Finally, I want to wish everyone a Happy Thanksgiving and all get to share it with the people you care about most. I'll have an update on the coldwave coming tomorrow afternoon after the turkey and football.

Snowfall Totals from Today





GRANBY 1.6 1039 AM 11/20 SPOTTER


PAXTON 2.5 1151 AM 11/20 HAM RADIO

So today was a nice little surprise. The snow quickly moved into the Boston area around 10AM this morning and reduced visibility quite a bit in a few places. In the heat of the snow, the visibility came down to between 1/2 to 1 mile. My unofficial reading for Woburn, MA is 0.5" The snow shut off around 1PM as the main shield of precipitation moved to the SE. The forecast does not hold any more snow for southern New England, but we could be seeing some more rain for Thanksgiving Day. Could be some sloppy football games on Thursday morning.

Tuesday's Rain/Snow

The forecast is looking very chilly for tomorrow. Highs should range from the low to mid 30's North to upper 30's to low 40's South, warmest down on the Cape and Islands. Precipitation will take all morning to reach eastern southern New England. We will finally see the precipitation move in after the lunch hour and it may at first be mixed with a few wet snowflakes here in the dashed areas, this includes the cities such as Hartford-Worcester-Boston-Lowell-Portsmouth, NH-coastal Maine. Areas southeast of here will just be too warm for any frozen precipitation. In the light pink area, we will see up to one inch of snow/sleet/ice. Most will fall early and likely change to drizzle as the precipitation winds down. Where it stays mostly wet snow with highs struggling to get above 32 degrees, up near Berlin, NH and the western mountains of Maine, there could be as much as 1-3" of snowfall. This isn't a big event, but if you get a coating of snowfall, it could mess up your drives.

There is a WINTER WEATHER ADVISORY for the Berkshires and southern Vermont, for some accumulating snow and light ice accretion.

Here is what the NWS out of Taunton is thinking about tomorrow.




We will see what the weather brings tomorrow.

Soggy Turkey Day

Thanksgiving Day is only a couple days away. The forecast is becoming more and more clear as we head towards the big holiday of football and turkey. First lets get through our short work week. This afternoon, there is a band of ocean effect showers that show up on the radar as rain showers down on the South Shore near Plymouth, but I wouldn't be surprised to hear of a few snowflakes mixed in as well. This morning there was a flurry in the Boston area with a few flakes seen around 8:30AM this morning. Tomorrow will start off dry but then the clouds will lower and a period of showers will commence. If the shield of precipitation gets in here before noon, we could be talking about a mix of rain and snow, changing to rain. Tomorrow will be another chilly one with highs in the upper 30's in Worcester County to low 40's elsewhere.

The warmth returns on Wednesday with highs in the mid 50's. Rain showers will likely develop in the nighttime hours. Right now there is a spread at how strong the Thanksgiving storm will be and its exact position, but all models are hinting at an Appalachian runner with southern New England in the warm sector, with highs in the mid 50's with showery rains, becoming heavier later in the afternoon. The GFS is the strongest with an actual strong storm developing along the front, while the NAM is just a front moving through our area. Either way, far reaches of northern New England may see some accumulating snow out of this as they will be removed from the warm sector much of the time.

That will move through and the New England area will cool off into chilly, but not exceptionally chilly conditions. Highs will be in the 40's on Friday through Sunday with moderating temperatures by Sunday. The next storm system will be a warm one coming up from the Southeast. The NAO will be soaring well into the positive range at this time, so we can assume the storm will remain far inland, sending warm moist air into the East.

The forecast of the NAO is for it to turn more negative by the first of December, so we could see a colder, stormier start of the first month of winter. We will see if that comes to be, as it seems like we are always 5-10 days away from that big storm or bigtime cold airmass, only to have the models change 3 -4 days before the event. It's a wait and see kind of forecast.

Saturday, November 17, 2007


Forget about that map from today. The GFS tanked again and the NAM was the winner overall. Most models have gone to a dry scenario. Don't expect much more that a few sprinkles of rain or 'snizzle' down on the South Coast and Cape later tomorrow.

Thats it. North of Hartford to Providence to Plymouth, MA, there will not be anything. Not even a flurry. We will mark this up as DISAPPOINTMENT NUMBER ONE for the winter season of 2007-2008.

It will be cold on Monday, however. Highs will stay in the 30's. We warmup thereafter. Did anyone say 60 degrees for Thanksgiving?

CLIPPER: First Call

This clipper system has been on and off for the past week. Early in the week, it looked like we would be getting something from this. Then the signal died. It died to the point where it was barely on the maps anymore. Now the GFS is back on the bandwagon and giving parts of southern New England heavy duty precipitation. However, the NAM, another reliable model is very dry. So if we break it down between the two most reliable models....

The GFS brings the 0.25"-0.50" of liquid to southern Vermont and New Hampshire. This would be mainly snow, so you can imagine that someone or many would see a general 3-5" snowstorm out of this, with rain along the Cape and immediate coastline, Boston being right on the line between rain and snow. It paints QPF up to 1"+ in parts of Connecticutt, so we could see 4"+ there. However the NAM barely brings any rain/snow light showers onto the South Coast with most of the precipitation missing SNE by 100-200 miles. Most of the precipitation would fall over PA and NJ. New York City could see its first flakes.

You can see that the models are AWFUL this season. They cannot even come into some kind of agreement only 24-36 hours before the event. This is a shot in the dark forecast for any meteorologist. If they side with one, they could bust badly, and even if they go in the middle, like me, they could still bust badly. If you call for a the first flakes, even if its a few flurries and it doesn't happen...its a bust. If you call for a few flurries and you get 5" of snow...its a mega BUST.

Basically, this forecast has BUST all over it. I know I will have to change this forecast, but this map is what my first call is. The South Coast will see a mix of rain and snow, mainly rain. Up to .25-.50" of QPF. Further north, where it will be colder, a sloppy 1-2" of snow will fall, highest in the highest elevations in NW Rhode Island and northeastern Connecticutt. Southern Worcester county could see a whitening of the ground as well. Then north of the Pike, expect flurries all the way to southern New Hampshire.

Thats my call for now. If we see the NAM come further north, these snowfall amounts will come up. If they side more with the NAM, don't expect much tomorrow. Timing on all this is delayed now. Mainly late Sunday afternoon through the overnight hours of Sunday. A delay of about 24 hours.

Dry Pattern Sets Up for SNE

After yesterday and this morning's heavy rains, cold rains this morning across southern New England with temperatures in the mid to upper 30's, just to warm for snowfall. It was a wet and windy ride to work early this morning, I, myself, got soaked heading into work this morning as I didn't have an umbrella or raincoat on. Not a smart move. Did you notice the difference a day makes? Yesterday the temperature hit 70 degrees in SE Mass. Today, temperatures have stayed in the 40's with windchills in the 30's this afternoon. Tomorrow will be much of the same and then we step down a couple degrees each day until we bottom out on Monday with highs rebounding only into the mid and upper 30's after morning lows in the mid 10's in the suburbs to mid 20's in the cities.

Thereafter, we will warm up BIG TIME heading into the Thanksgiving holiday. High temperatures on Wednesday will get into the 50's once again and then we could have a really mild Thanksgiving Day with highs in the mid 60's, believe it or not! We will warm dramatically ahead of a cold front loaded with rainfall and ripples of low pressure along the front that will douse the area with heavy rains late Thanksgiving night and early Black Friday. Expect it to feel more like Christmas after Thanksgiving as the coldest shot of air we have seen in a while for November will move into the area for Thanksgiving weekend, later in the period.

Current projections show that the upper Plains, MN, ND, SD, MT, could see temperatures only manage 0's and 10's for highs the week after Thanksgiving weekend with subzero lows. That cold will move east.

Blustery Friday to Wintertime Cold

We have ourselves a blustery Friday on the way. How was today, though? The temperature hit 70 degrees at about 10AM this morning in Taunton, MA for about fifteen minutes. Then the rain moved in around 3PM in eastern Massachusetts and fell heavily for about three hours, causing ponding in the streets and fender benders all around town this afternoon. It was a mess. A second batch of rain is moving up from the Atlantic as we speak and this will be over our area as the temperatures continue to drop through the night, into the 30's for eastern southern New England. As that happens, any raindrops will turn over to snowflakes for the morning drive, but there will not be any accumulation of the sort. Just decorative snow to go with that Christmas music for the car ride into work. That will all wrap up early in the morning, any time before 9-10AM and then it won't be all that cold, mid-40's, but it will be windy, with windchills in the mid-upper 30's all day. It will have that damp-cold feeling all day.

Wintertime cold moves in after a front passes through on Saturday night and we will only see highs in the middle 30's on Sunday afternoon! The clipper system looks to continue heading to our south as even now the GFS has backed away from its once promising snowfall forecast from yesterday. That said, there may be a few snow flurries or sprinkle south of the Mass Pike early Sunday morning, but that would be about it. Nothing even remotely significant. A nonevent. Waking up Monday morning will be tough with widespread lows in the 10's in southern New England will lows in the single digits up North.

However, the NAO eases and heads back POSITIVE later next week and that will allow the warmth to move over the northeast once again, with temperatures getting back to 60 degrees by midweek and that would be Thanksgiving. Right now, I think the Thanksgiving holiday looks great with partly cloudy skies and temperatures in the low 50's for the 10AM games. Its way out there, but at least there won't be weather on that day for the games, at least thats how it looks now. These models can flip on a moment's notice. So, stay tuned, as usual.

So get ready for the possibility of our first flakes tomorrow morning and get ready for a really chilly weekend.

Balmy Thursday

There is one last balmy day in store for southern New England. Tomorrow morning will start off very mild, in the 50's, with a gusty southerly wind, up to 20-30 mph. The wall of water will only be into Springfield, but it will gradually head its way down the Pike and be in Boston before noontime. The rain will be heavy from noon until about 8PM. All said and done, we will see between one-half and one inch of rainfall. A few places will see up to an inch or more of rainfall. The rain will taper during the overnight hours, where in northern New England we will have the rain change over to snowfall where there is currently a Winter Storm Watch for 7"+ of snow in northern Vermont and northwestern Maine, mainly elevations above 2800'. Early Friday morning there may be a few stray flurries all the way down into the Boston metro area, but that would be just about it.

The snow will fly much of the day in northwestern Maine, where some mountain resorts could come in with close to 10" of snowfall, heavy wet snowfall at that. Then we all have a blustery cold Friday with highs in the low 40's. The weekend looks to be mostly dry with highs on either side of 40 degrees.

There is a small chance that we could see some snow with a clipper on Sunday, but most computer models are taking this clipper further south and the only model showing any snow for southern New England is the GFS and it has een awful as of late, so I am not going with its forecast, just yet.

Check in tomorrow.

Thursday Soaker

We have one heck of a soaker coming for Thursday, all day. The rain will likely start early in the day and stay moderate to heavy throughout the day as a frontal system moves slowly through the area. A quick shot of 1-2" of rainfall is likely throughout all of New England, through Thursday afternoon. Then all eyes shift south to just off the Delaware and New Jersey coasts. A little area of low pressure will try to get its act together on the front and surge an area of precipitation into all of New England starting later Thursday into the evening and overnight hours. How much precipitation we get is still in question and how cold it will be will determine if we see our first flakes for the 2007-2008 season. 12z GFS was a little more ominous with its snow signal for southern New England compared to the 18z GFS, but we will see. NAM is showing backlash snows for southern New England, so it cannot be discounted, I just have hard times in seeing snowfall after heavy rains here in southern New England. In the Boston area, we rarely go from a balmy rain to a snowfall, not even accumulating snowfall. Its possible, but not likely in the Boston to Hartford areas.

More likely, parts of Maine will see more snowfall. Good for the ski areas, at least. I'll keep you updated.
