Sunday will feature a winter mix for much of the morning and early afternoon. Areas along the immediate shoreline are generally clear, as air temperatures have climbed to between 30 and 30 degrees. Although just inland, the air and surface temperatures are well below freezing.
Sleet and freezing drizzle will continue throughout the afternoon, particularly in northern areas of TC. An extended period of freezing drizzle is likely in Litchfield County where they could see a tenth of an inch of ice. While this is not enough to damage trees or power lines, it is certainly enough to create dangerous driving conditions on any untreated surface.
We will see temperatures gradually rise above zero for most of Connecticut. There is a caveat to this, as temperatures in northern Litchfield County will likely stay around or just below zero in the afternoon.
Once this system has been passed, our attention turns to the extreme cold which will switch to the state on Tuesday. High temperatures on Tuesday are only expected to reach 12 degrees in the Hartford area with single-digit high temperatures in parts of northern CT.
The most concerning part of the cold is the wind chill as we head into Tuesday and Wednesday mornings. Wind chills can range from -15 to -25 degrees, which is considered dangerous.
