A strong backdoor cold front, driven south and westward by advancing (very) cold air associated with a large Canadian high pressure situated over James Bay, is sliding through the Northeast and New England today and will be positioned well south of the region on Sunday.
As a result, we are going to have quite the weather flip-flop over the next 24 hours.
Deeper cold will advance into the area tonight, sending temperatures tumbling into the 30s as gusty east and northeast winds persist.
The worst of the weather comes tomorrow as temperatures hold in the 30s under overcast skies and pockets of light rain and sleet develop over the area. Wind chill values will be stuck in the 10s and 20s as east and northeast winds gust to 30 mph at times.
