Another Nor'easter

Another Nor'easter could be in the works for later this week and weekend. The computer models are continuing to show this storm system with marginal temperatures between rain/snow. Its going to be a real close call. First of all, we have a rainy Tuesday coming with a bout of some heavy rainfall associated with the frontal system. All said and done, much of southern New England will see between one half and one inch of rainfall out of this storm system. This will usher in some much colder air later in the week with highs in the 40's for the rest of the week with highs likely in the upper 30's on Friday ahead of a storm sytem coming out of the Great Lakes and redeveloping along the coast and ever so slowly moving up to Nantucket with a band of precipitation making it all the way into southern Vermont and central New Hampshire. This could last into Saturday with a tossup between rain and snow. Generally, the further away you get from Boston, the better chance you will have at seeing some snow.

Here is what the Boston Forecast Discussion is saying about this event...

HIGH PRESSURE WILL SLIDE OFFSHORE ON FRIDAY AS A FAIRLY POTENT UPPERLEVEL TROUGH APPROACHES FROM THE WEST. THE 00Z GLOBAL MODELS HAVECOME INTO BETTER AGREEMENT WITH EACH OTHER REGARDING THE EVOLUTIONOF THE APPROACHING SYSTEM. ALL OF THEM /EXCEPT THE ECMWF/ NOWDEVELOP A COASTAL LOW OFF THE MID ATLANTIC COAST SOMETIME FRIDAYNIGHT...THEN MOVE IT NORTHEAST WELL TO THE SOUTHEAST OF NANTUCKETSOMETIME SAT OR SAT NIGHT. THE 00Z OP GFS...00Z GFSENSEMBLE...UKMET...GGEM ARE IN DECENT AGREEMENT WITH THIS.WILL

THEREFORE INTRODUCE LOW CHANCE POPS ACROSS THE SOUTHERN HALF OFTHE CWA FRIDAY NIGHT INTO SATURDAY NIGHT. WILL HAVE TO WAIT FOR THEECMWF TO COME INTO BETTER AGREEMENT BEFORE HAVING ANYTHING MORE THANLOW CONFIDENCE. HOWEVER...IF THE 00Z MODEL CONSENSUS PANSOUT...PORTIONS OF SOUTHERN NEW ENGLAND COULD SEE THEIR FIRST MEASURABLE SNOWFALL OF THE SEASON /ALBEIT QUITE LIGHT/. THE COASTALPLAIN LIKELY STAYS LIQUID AS BOUNDARY LAYER TEMPS WILL BERELATIVELY WARM.

We will see how the computer models go this afternoon....
