50-below zero wind chills possible in parts of CT later this week, weather service says

After a brief round of snow or rain showers Tuesday morning, Connecticut is bracing for its lowest temperatures in seven years when a "dangerously cold air mass" arrives later this week, the National Weather Service said.

Little or no snow accumulation was expected on Tuesday, which will be mostly cloudy with highs ranging in the 30s to low 40s.

But by Friday, the weather service says temperatures will significantly plummet.

"A dangerously cold air mass is expected to settle over the region Friday and Saturday," the weather service's New York office said in a bulletin . "Wind chill values during this time may fall to as low as 10 to 20 below zero for coastal locations, and 30 below in the interior."

Some inland regions of the northeastern part of the state could see wind-chill values as low as 50-below zero , the weather service warned.

The frigid temperatures are the result of arctic air moving into the region. In some areas, it's expected to produce the coldest temperatures since February 2016 .

On Monday, Gov. Ned Lamont announced he was activating the the state's severe cold weather protocol from noon Thursday until noon Sunday. The move allows the state and local governments to coordinate with the United Way to get people shelter from the weather.

“Don’t be fooled by this mild weather that we are experiencing right now, because it looks like a blast of arctic air and winds will impact Connecticut later this week and this weekend,” Lamont said in a statement issued by his office. “With the kind of severe cold weather that is headed our way, frostbite can develop on exposed skin in under 30 minutes. Spending long periods of time outdoors in these conditions is not only harmful, it can be fatal."
