Expect a period of unsettled weather Tuesday and Tuesday night, followed by colder temperatures through the end of the work week.
A weak area of low pressure is moving well south of New England today and will bring minor impacts to the area. With cold air in place we can expect light snow throughout the area, with the possibility of a bit of rain along the coast. As the low moves into the open waters of the Atlantic tonight some intensification may take place and this could enhance the precipitation for a period of time early tonight. Northeast winds will turn more northerly and drag colder air into our area overnight. With the low pulling away Wednesday we still remain mostly cloudy near the coast, with a chance of a few showers of rain and or snow. Interior sections have a chance of partial clearing for the afternoon.
Snowfall totals north of Boston are only expected to be about one inch or less, with a few spot two inch totals possible west of the city. The best chance for snow totals of one to possibly three inches are through interior southeast Massachusetts. If there is any accumulation in the northern and western suburbs the most likely period will be later this afternoon and this evening.
High pressure moves in for Thursday and Friday. Expect it to be cold and breezy, with generally partly cloudy skies for both days. High temperatures will struggle to make it out of the 30s Thursday, remaining in the 30s on Friday.
As we get into next weekend clouds return and there is a chance of showers later Saturday or Sunday, with temperatures recovering a bit as highs nudge back into the low 40s.
