A cold front has moved east of the area overnight. The passage of the front puts an end to the mild temperatures of the past few days as we will trend to much cooler weather into Monday. A period of snow showers or light snow will overspread the area by mid morning and will continue for a few hours. Up to an inch is possible, especially away from the coast. Skies remain mostly cloudy this afternoon, although a ray of sunshine is possible. Much cooler temperatures as highs range from 35 inland to near 40 on the coast.
The front stalls offshore during Saturday and low pressure will also be developing south of New England along the frontal boundary. An intense ocean storm will develop, but the question remains when and where. Most of the computer models have the low well southeast of Nantucket Island, with a few models suggesting a closer pass toward the coast. Either way, we should see snow redevelop this evening and continue overnight. It looks to be a light snow event locally, with southeast portions of the state seeing the potential for more snow. Lows tonight fall to 20 to 25 degrees. Winds will come around to the north at 10 to 15 mph and increase tonight as winds could gust to over 30 mph. If the ocean storm comes closer than expected the snowfall accumulation increases. Further out to sea and we get very little if any snow at all. It is a close call either way. The National Weather Service has issued a Winter Weather Advisory from 7 pm this evening until 1 pm Sunday. Total snow accumulation of 2 to 4 inches through mid day Sunday.
What is for certain is once the storm pulls away toward Nova Scotia later Sunday and Monday we get quite cold and very windy here Sunday through Monday. Blustery conditions will make it feel quite uncomfortable outside as winds are forecast to gust upwards of 40 or 45 mph from the northwest. Snow comes to an end around mid day, although an afternoon snow shower is possible. Skies remain mostly cloudy into Sunday night, with partial clearing by morning. Temperatures on Sunday only climb to near 25 degrees, dipping to 12 to 17 degrees Sunday night as it remains windy through the night.
Monday will be partly to mostly sunny and windy. Gusts to over 40 mph are likely. Highs of 25 to 30. Daytime wind chills will feel in the teens considering the gusty winds.
Monday night will continue cold, however those gusty winds should be tapering off. Lows near 20 under a partly cloudy sky.
Another storm system approaches from the Great Lakes Tuesday. Temperatures moderate a bit as highs jump back to near 40. We could see a spell of light rain showers Tuesday, possibly mixed with snow, with snow showers at night as temperatures drop into the 25 to 30 degree range.
The weather returns to partly cloudy on Wednesday, highs of 35 to 40 degrees.
