Significant snowfall amounts are expected on Sunday into Monday, with Connecticut facing 12 to 18 inches of snow from this major winter storm. Here's the latest timing (in three-hour increments) of how the snow accumulation is expected to progress across the state.

Gov. Ned Lamont has extended the state's severe cold weather protocol into Thursday of next week. The protocol allows officials to coordinate opening warming centers and providing shelter for those who need it. It went into effect Friday and was set to expire Wednesday before the extension into next week.

For the fourth time this month, Gov. Ned Lamont is activating Connecticut’s Severe Cold Weather Protocol due to a blast of extremely cold air that will impact the state.

The massive winter storm that has left thousands without power in the southern U.S. is expected to bring heavy snow and some sleet to Connecticut on Sunday.

The forecast said Connecticut on Saturday will experience temperatures in the high teens. However, the rest of the week as well, Jan. 26 through Jan. 30, is expected to see sub-freezing temperatures, with overnight low temperatures in the teens and single digits.

A blast of arctic air is headed into the region on Monday night, leading Connecticut officials to activate the state’s severe cold weather protocol.

Forecasters are monitoring a potential second storm that could strike Connecticut as it moves up the East Coast this weekend.
