We hit bottom in the single digits to mid teens this morning across Eastern Pennsylvania to Southern New England as arctic air has settled into the Northeast and Mid Atlantic states. This is only the beginning because an even colder arctic air mass is on its way for the end of the week and into the weekend. We will see a fair amount of sunshine today but it will be breezy and cold with high temperatures just reaching the upper teens and lower 20s in most places. Southern New Jersey and points southward could see middle 20s for highs. This leads to a very cold night tonight under clear skies. By morning lows across the entire area will be in the single digits to lower teens in some of the warmer urban locations. This first arctic air mass will settle overhead Wednesday which will be a day with some sunshine. However temperatures should moderate some ahead of the next arctic cold front that will push its way through Thursday. We will see highs Wednesday afternoon reach the low and middle 30s. A warm front will be going by across Upstate New York and New England but the precipitation with that will go to our north.
Another arctic front will approach and move through Thursday and ahead of this we will see temperatures reaching into the 40s with some sun and clouds but the warm-up Thursday is short lived. Colder air will begin to arrive ahead of what is the coldest air mass of the winter season so far. The coldest air will be with us Friday night right through Sunday. This arctic front will settle across the Deep South from the Carolinas to Texas and this opens the door for precipitation to develop in the Southern Plains Friday and gradually spreading eastward through the Lower Ohio Valley and Deep South later Friday and Saturday.
