Snow and cold temperatures are on the way, but neither will be around for too long.
Low pressure will develop off the Carolina coast tonight and head northeastward, passing well south and east of New England on Friday. It will spread some light snow into the region Friday afternoon and evening, mainly south of the Mass Pike, but possibly as far north as the MA/NH border. For much of the region, this will be “nuisance snow”, with a coating to an inch of accumulation. However, along the coast from Plymouth County to Cape Cod, things will be a bit different. Northeast to northerly winds off of the relatively mild Atlantic, will produce some ocean-effect snow. This is similar to the lake-effect snow you hear about near Buffalo, but not nearly as heavy. It will enhance to snow near the coast, with the potential for 2-4 inches in spots, maybe even a few heavier amounts. The storm pulls away Friday night, and some very chilly air settles in behind it. Temperatures may struggle to reach 20 in parts of the region on Saturday, with sub-zero wind chills, especially in the morning both Saturday and Sunday. High pressure moves off to the east for Sunday and Monday, allowing temperatures to begin to moderate. We will some clouds starting to move in again on Monday ahead of another storm system headed our way.
