After the coldest start of the season with some places getting to 10 below zero Saturday morning, we have a nice recovery this afternoon. It is a pretty cold Saturday -- both pretty and cold.
But at least we have warmed up to freezing, and the wind is not an issue today. High pressure from Canada is large and in charge. We start changing it Saturday night though, on the backside of the high-pressure, the air will come around a little bit from the southwest, with less cold in the forecast overnight tonight.

Colder air will come back in with a brisk breeze from Canada Tuesday. High temperatures will be in the 20s north and 30s south, under partly to mostly sunny skies.
High pressure moves to our south Wednesday, after a cold start we should warm back up to close to 40 degrees with fading sunshine.

There’s a dramatic cold front with a rain-snow line all the way down to near Atlanta on Christmas morning. Colder air will be racing into New England from the southwest during Christmas Day.
