The temperature could drop below zero degrees in parts of Connecticut tonight, with the National Weather Service (NWS) issuing a Wind Chill Advisory for much of the state.
“The frigid conditions will be dangerous to those venturing outside.,” the NWS said. “Prolonged exposure may cause frostbite.”
The Wind Chill Advisory is in effect from 11 p.m. Thursday to noon Friday in southwestern Connecticut — including northern Fairfield and New Haven counties — as well as all upstate counties, where wind chill values could dip to 25-below-zero.
In Shelton, the air temperature should drop to 9 degrees and the wind chill values may go as low as 5-below-zero, the NWS said.
There also is a possibility of more light snow late Thursday night into Friday morning, the NWS said.
Don’t look for a warming trend soon, with one upcoming overnight low predicted to be 4-below-zero — and that’s without the wind chill.
According to the NWS forecast for Shelton, high and low temperatures in Shelton during the coming days will be:
Friday: Daytime high of 14 degrees, nighttime low of 4 degrees.
Saturday: Daytime high of 25, overnight low of 10.
Sunday: Daytime high of 14, nighttime low of 4-below-zero.
Monday: Daytime high of 16, overnight low of 3.
Snow expected Saturday
There also is the potential for up to 5 inches of snow on Saturday in Shelton. Snow that day is “likely,” the NWS said.
The NWS expects the snow to start around noon and continue into early Sunday, with the potential for an inch during daylight on Saturday and another 2 to 4 inches at night.
