Coldest temps since February arrive this week

November 19, 2018

After several inches of snow, our taste of winter continues this week with the coldest temperatures since February.

The coldest temperatures - as low as 10 degrees - are expected on Wednesday and Thanksgiving night.

The last time it was this cold was on Feb. 3.

The bitter cold temperatures - between 15 and 20 degrees below normal - come from a cold Arctic air mass that will arrive Wednesday.

The National Weather Service says in its forecast discussion that the “arctic front will pass through the region Wednesday evening, possibly triggering a few snow showers. There is also the possibility that once the front taps into the moisture from LI Sound and the Atlantic that additional snow showers could develop.”

On Thanksgiving Day, high temperatures will be in the 20s.

“Highs on Thursday are not expected to reach the freezing mark, with 20s areawide, highest near the coast. Wind chills will only reach the teens across much of the area. The combination of clear skies and diminishing winds Thursday night will allow for ideal radiational cooling conditions with the coldest temperatures ofthe season thus far expected.”
