No 5 day tonight, but I will tell you one thing, the next week will be a crazy weather week. Tomorrow Friday will be a rather quiet drizzly dank day with highs in the upper 60's with a raw NE wind. Its kind of a dull day all around. I'm sorry to say that Saturday won't be much better. Highs will be approaching 70 late day with some partial breaks of sunshine. Not totally sure of that yet.
Then comes the warm air for Sunday with sunny skies and highs in the upper 70's, approaching 80. You think that is nice, wait until Monday when there will be unlimited sunshine and highs UNBELIEVABLE, MID to perhaps UPPER 80's with a stiff SW wind. That will be short lived though as a major cooldown is expected later next week when temperatures Tuesday will not be quite as warm with scattered showers and perhaps a rumble of thunder. Highs in the 70's.
The cool air will be noticed from Wednesday on. Right now there is a big batch of unseasonably cold air in western and northern Canada and a piece of this will be breaking off into the northern Rockies this weekend, where believe it or not, there are WINTER STORM WATCHES posted for highest elevation areas for snowfall accumulation of 6-12"+! Even the valleys could see a few snow showers and flurries, mixed in with the rain. This pool of cold air will break off from the main area of cold in central and northern Canada and move through the upper Midwest. Major cities like Minneapolis, Des Moines, Green Bay, and perhaps even Chicago could see their first frost and freeze. Lows at this time will be in the 20's and 30's in the northern Plains and Great Lakes. This will be migrating towards BOSTON!
Expect it here Wednesday in a much modified form with highs in the lower to mid 60's with ample sunshine. No snow here. Can be so sure for the mountain peaks, like Mount Washington in NH. A few of the highest peaks may get a quick dusting of snow when this cold airmass moves in. Sorry to say, but my best bet is by this time next week, much of Southern New England's growing season will be all but over or just about to be over as lows later next week will certainly be dipping to around or below the 32 degree isotherm. Only places like the immediate coast and urban heat islands like Boston and Providence may escape frost. You heard it here first.
By the way, there are now signs of "EL NINO" forming in the Pacific Ocean. This has the steriotype of meaning warm and wet for much of the nation, but that is only during a STRONG "El Nino." In a weak to moderate "El Nino" as is forecasted, the East Coast and especially New England can experience harsh snowy winters like we saw in the winter of 2002-2003. If you don't remember, Boston's International Airport received over 72" of snow that season, with the first significant snowfall the day before Thanksgiving.
Just something to watch, stay tuned.
