A weak disturbance Wednesday night will mark the passage of a warm front – the leading edge to new, milder air – through New England. On the front edge of the new air, the collision of antecedent cool air and the new warmth will likely cause snow showers in northern New England.
Such snow will be accumulating a coating to one inch and perhaps a scattered snow shower from late evening to just past midnight in southern New England.
With limited impact from any Wednesday night snow showers for most of us, attention will turn to the milder southerly wind taking hold Thursday. This wind will bump temperatures to around and over 50 degrees, even if the clash of incoming warmth with retreating cold results in mostly cloudy skies.
With no focused atmospheric disturbance Thursday, clouds are unlikely to produce much in the way of rain, but Friday’s approach of a cold front from the west will prompt development of scattered rain showers, even as high temperatures reach 60 degrees.
Though not expanding rapidly in heavy rain, you’ll notice potholes in New England roadways slowly opening wider this week, and that will accelerate a bit on Friday.
Weekend weather will be fairly benign with dry and pleasant conditions expected Saturday and colder, brisk, but bright weather on Saint Patrick’s Day.
The big South Boston St. Paddy’s Day parade will air live Sunday on necn and looks to be sunny and cool with temperatures in the lower 40s and wind chill values in the 30s. Next week features the first day of spring in the exclusive First Alert 10-day forecast, when we could see some showers with seasonable temperatures likely.
