PM Update: Even colder evening on the way
Temperatures plummeted into the upper 20s to low 30s early Thursday morning, and although it remained warmer in the city, many interior areas saw the growing season end. Such was the case for Sussex, Morris, Warren, Somerset and Hunterdon counties in New Jersey. Tonight will offer even colder temperatures, owing to a cold airmass settled in aloft as well as clear skies and light winds.
850mb temperatures have fallen to below -4 throughout much of the area — and temperatures responded today. Highs topped out in the 50’s with blustery west winds, a stark reminder that winter is in fact on the way. The same feel will be in the air tonight. Dew points have fallen dramatically, and the clearing skies and light winds will allow for better radiational cooling. Temperatures are expected to fall into the upper 20s across the interior — and the 30s even in the city.
