Impressive Weekend Chill

eps_t850a_noram_25It’s becoming more and more likely that some brutal cold will settle over New England this weekend. A blob of 850mb temperatures of more than 20C colder than average will lead to some impressively cold temperatures. This afternoon’s GFS run shows 850mb near or below -30C over a good chunk of New England Saturday night – that is some impressive with!

So – how cold will it be? Right now we’re predicting a low of -7F at Bradley Airport Sunday morning along with wind. Wind chills below -20F are possible across parts of the weekend. Painfully cold stuff.

There is the potential for some snow prior to the cold’s arrival on Saturday morning though that is presently a low probability event. Odds are no better than about 1 in 4 for accumulating snow. We’ll have to watch it, however!
