Weather rollercoaster could end with Thanksgiving Nor’Easter
As most of you could probably tell by simply walking outside, another mid-winter airmass has filtered into the region today, and will set up another very cold night tonight. As high pressure settles into the region this evening and tonight, winds will subside to nearly calm levels. When this is combined with clear skies and a very dry atmosphere, ideal conditions for radiational cooling will be generated. This leads to lows in the upper teens in the interior, and lower 20s near the coast, with perhaps mid 20s in the warmest urban areas.
Afterward, the trend will be for moderation. This is because the high pressure will be sliding off the coast, giving way to a ridge and a return southwest flow. This will help to significantly warm temperatures aloft, but surface temperatures may be a bit more stubborn to warm up due to the presence of high pressure wedging the colder air. Still, though, the shift in wind direction and the ridge will be enough for temperatures to warm to around 40 or the low 40s tomorrow afternoon.
It won’t be until a warm front crosses the area tomorrow night that the weather will start to get a lot more interesting.
