A cold front will front will move through southern New England late tonight into tomorrow morning with a weak wave of low pressure developing along it to our south. This wave will bring a swath of snow to southern New England. It may start as a bit of a mix during the wee hours then change to plain, light snow through the morning commute.
Along the Mass Pike including greater Springfield may pick up 1-2" of snow with a coating to 1" north and even up to 3" across parts of Connecticut. North of route 2 in Franklin County there may not be much at all. The issue could be that temps will be falling through the morning so if roads become wet, they could ice up quickly, especially just south of us.
High pressure will build in tomorrow afternoon, ushering in the cold Arctic air again to end the week. Temps top off near freezing tomorrow then fall in the afternoon. Temperatures plummet to around 0 by Friday morning and we end the week with some sun and highs in the teens to near 20. Fortunately the wind will be light on Friday so wind chills will not be too bad.
It still looks as though a coastal storm will pass out-to-sea missing us this weekend.
