The chance for rain on Thursday night and into Friday is at 90 percent, with daytime high temperatures on Friday dipping to around 50 degrees, according to the National Weather Service.

The precipitation is expected to continue on Friday, when the chance of precipitation is around 70 percent, followed by gradually clearing for the weekend.

“A storm system will likely bring the first accumulating snow to the higher elevations of the central Appalachians and the interior Northeast late week into the weekend,” the National Weather Service’s Weather Prediction Center said. “In the low elevations, precipitation will mostly fall as rain.”

Wet snow could mix in at times as colder air wraps in behind the storm, the National Weather Service said.

WFSB is calling both Thursday and Friday “First Alert Weather Days,” due to the storm system.

It predicts showers will arrive Thursday morning, becoming steady rain for the afternoon and evening.

“Rain could be heavy at times,” WFSB reports. “As an area of low pressure strengthens, colder air wrapping around the system could allow rain to change to wet snow across the NW Hills overnight (Thursday) and into Friday morning. While impacts from the snow will be low, a slushy accumulation will be possible on grassy surfaces.”

WFSB predicts Friday will be much colder, with highs in the 40s, along with gusty winds.

“Periods of rain continue through the day with more wet flakes possible in the Hills,” WFSB reports.

WTNH predicts the storm will bring a “chilly rain” for most of Connecticut on Thursday and Friday.

“The opportunity for some wet snow to mix in for western and northern Connecticut, with some minor accumulations possible for the highest elevations,” WTNH reports. “Colder temperatures will dominate through Sunday with gusty winds as well!”
