Snow Ends Bitter Cold Arrives Friday Into Saturday
Single Digits & Below Zero Temps
The latest in a series of weak waves of low pressure is moving offshore and taking any snow that fell overnight with it. As this clears the coast we will have leftover clouds giving way to some sunshine. It will be a cold day with temperatures actually a little below average. Highs will be in the mid to upper 30s. This winter days like this have been few and far between.

This wave of low pressure will push the frontal boundary along the East Coast further south into the Carolinas and then another wave develops on that front. However this wave will pass well to our south with no issues here. However it will combine with a low in Eastern Canada to produce a major storm there. This will drive bitter cold arctic air southward into New England. There are no issues Thursday however which will start out in the 20s and highs will reach the upper 30s and lower 40s with some sunshine and high clouds.
Friday morning the arctic front passes quickly through and it looks like it does so with no snow squall activity. Then the focus will be on falling temperatures and we settle in the 20s Friday and head our way down into the teens in many locations by later afternoon. There will be a gusty north wind of 30 mph or more and that means subtract 10 to 15 degress off the temperature to give you the effective wind chill. There will be some sunshine Friday as this bitter air arrives but it will be completely ineffective.
Saturday morning lows will be in the single digits to below zero from south to north. Models this winter have had difficulty handling the magnitude of the cold air air masses as we saw in December’s arctic blast where temperatures were 5 to 7 degrees to high. Models have backed off on some of the colder readings below zero shown over the last few days but how low temperatures get will depend on the wind direction staying more from the north and not turning to the west before daybreak Saturday. Either way it is going to be bitter cold and again subtract 10 to 15 degrees from the air temperature and you have below zero windchills just about everywhere.
What is probably more remarkable will be just how fast the bitter cold air pulls out. By Saturday afternoon highs will be in the upper teens north of NYC to mid and upper 20s Southern New Jersey and points southward. Saturday night will not be as cold with lows in the mid to upper teens inland and lower 20s warmer urban areas. Sunday we will see temperatures bounce sharply higher with sunshine and arriving clouds. Highs will be in the 40s!
This means that if we get precipitation Sunday night as a low develops offshore and moves east, it will be rain and no one will see a flake or an ice pellet! Even areas in Upstate NY where temperatures Saturday morning will be double digits below zero might just see rain or a mix Sunday night into Monday morning. Next week it is back to the same ole pattern that has dominated the weather in the last 5 weeks. That means no cold air and temperatures running above average. Most of next week should be on the dry side.
