Forecast discussion: A weak disturbance is helping to bring some snow showers over eastern Massachusetts at the moment. Based on the radar loop, all precipitation will end by about 10 p.m. in the state. We have seen enough snow to cover the cars here in Pawtucket, RI, with just a coating on the grass and streets. However, be careful if you have to drive tonight, as the wet streets will become black ice.
A much strong cold front will pass through New England on Sunday, helping to bring our temperatures below normal once again. We will only see highs in the lower 20’s, but increasing cloud cover during the late afternoon will keep temperatures warm Monday night. By this time, a weak warm front will help create some light snow showers by Monday morning. However, temperatures will increase above freezing. So, any snow showers will change to rain showers. Any showers will end by the evening commute.
By Monday night, another blast of cold air will return to New England, and our temperatures will barely reach 20 degrees for highs on Tuesday. As we move into the end of the week, winds will slowly turn back to the south and southwest, allowing for warmer air to move into New England. Despite a small cold front from Canada Thursday night which will bring snow showers, temperatures on Friday will be near freezing. Temperatures will go above freezing next Saturday. A low pressure system in the Tennessee River Valley will extend a warm front into the Mid-Atlantic. So, any snow showers early Saturday morning will changeover to rain showers by mid-morning. Once the cold front comes through Saturday night, temperatures will remain in the middle teens into next Sunday morning.
