Today has been yet another in an impressive stretch of days below-freezing across the majority of the Northeast! Conditions were mainly calm, with patches of mid to high level clouds racing from southwest to northeast due to a strong/developing jet stream over the Northeast. An area of high pressure has been quickly moving offshore, which has shifted winds to the south over portions of the Mid Atlantic and southern New England. This subtle change was enough to bring in temperatures in the middle to upper 20’s for most of the NYC metro area, with 30’s further to the south. As we head into the night, we expect cloud cover to gradually increase as the large area of low pressure over the western Atlantic Ocean begins to expand substantially to the west and ushers in some mid-lower level clouds. Southerly low level flow will keep conditions a bit warmer than the past few nights, but expect lows to stay in the lower to middle 20’s over the immediate NYC metro, with upper teens likely to the north and west. Things should stay dry for most of the area up until midnight, when some initial light to moderate snow may begin to nose into the southern portions of New Jersey and Pennsylvania.
