That was quite the weekend, wasn’t it? There was plenty of incentive to shed coats and don sunglasses with temperatures soaring through the low 60s for much of New Jersey on Saturday. Today we’re in a different air mass, with high pressure scooting by to our north, drying us out and wiping away Sunday’s cloud cover, and setting the stage for some wintry weather tomorrow in northern New Jersey.
While temperatures today have climbed to about 50 degrees, dew point temperatures are simultaneously falling. This will allow for temperatures to quickly drop once the sun sets tonight, and we will bottom out below freezing for the northern half of the state. As the high pressure centered over New England retreats to the northeast tonight, a wave of low pressure will spread moisture across New Jersey tomorrow. For southern and central New Jersey, this spells rainfall for the morning commute. Further north, a period of snow looks likely before warmer air wins out both at the surface and aloft. North of Route 78, there could be modest accumulations on unpaved surfaces, with the most likely to see snow being those in higher elevations of Sussex, Passaic and Warren counties. Here, a few inches could hamper the evening commute.
Tuesday night into Wednesday, spotty rain showers will accompany a surge of warmer air as a strong low pressure center over the Gulf states climbs north through the eastern Great Lakes. Wednesday afternoon and night, a slug of moisture, both Pacific and Gulf of Mexico in origin, will bring heavy rain to the state. This is the big weather story this week, as two inches of rain could fall in this time frame, putting flooding pressure on small streams and the usual low-lying flood prone areas.
Thursday the low pressure center presses into southeast Canada, and our winds swing around from the northwest, ushering seasonal cold back across New Jersey. The rest of the week looks fair, with daytime highs in the low 40s, and overnight lows just below freezing. There are some signals for wintry weather the first week of March, but we have plenty of time to worry about that. For those of you who are ready to be rid of snow, ice and cold, take solace — astronomical spring is less than a month away!
