The weather system could cause periods of moderate to heavy snow bands and/or snow squalls Saturday afternoon and into the evening, the National Weather Service said.
Up to 2 to 4 inches of snow is expected across southern Connecticut, with more possible in some areas, especially in areas of higher elevation and farther inland. Winds of 18 to 21 mph with gusts up to 32 mph will bring periods of blowing snow, especially after 3 p.m. High temperatures will be in the 20s.
Hazardous travel conditions are likely as heavy snow combines with strong winds to reduce visibility, the weather service said. Untreated and elevated roads will be covered rapidly.
Sub-zero wind chills are expected for Saturday night into Sunday morning as part of the arctic wave.
Chance of precipitation is about 70 percent with up to an inch of accumulation possible.
Snow showers could continue overnight into Sunday, with areas of blowing snow. The low will be about 10 degrees with wind chill values as low as -1.
Sunny skies will return Sunday, but chilly temperatures will remain, with highs only getting into the 20s.
