Forecast discussion: Well, on a day that every state in the U.S. had a city or town reach 32 degrees or below this morning, we shouldn’t be complaining about the weather. With 86% of the continental U.S. with below freezing low temperatures, this has not happened since 1976. After receiving 1.40 inches of rainfall in Boston, high pressure ridging from the southwest brought us a bright, sunny day. However, the strong winds helped make the wind chill temperature make it feel like the middle 30’s. Of course, it could be worse; Buffalo, NY has received about 4 feet of snow since Sunday, and by the time the lake effect snow finally ends, they may receive a total of 5 to 7 feet by Wednesday afternoon.
For us, we will not be seeing any snowfall. The high will continue to give us clear skies this evening and mostly sunny skies for Wednesday. However, temperatures tonight will fall to the lowest level of this autumn season. For Wednesday, high temperatures will struggle to go above freezing. The average high temperature for this time of the year is about 52 degrees.
As we head into Wednesday night, a low pressure system in the Canadian Maritimes may help bring some ocean effect snow showers over inland areas after midnight early Thursday morning. The high will take over by the morning commute, and I am not expecting any accumulations.
We will see limited sunshine on Thursday, thanks to some cloud cover from that low. However, warmer air will begin to move over the area, as winds turn more to the southwest. But, winds will calm by Thursday night, lowering our temperatures back into the middle to upper 30’s for Friday and Saturday.
As we enter Sunday, a low pressure system passing into the Great Lakes will have a weak cold front ahead of it. The front will help create some showers by the late morning, and continue into the late afternoon. However, there will be a lull before another wave of showers and rain moves back into New England from a second low along the cold front. The rain will return by Tuesday morning before coming to an end by the end of sunset. You will notice that the temperatures will increase into the lower 50’s by Sunday, and the lower 60’s by Monday. At this time, the computer models are still in disagreement in the timing of the precipitation. So, my confidence in the forecast after Sunday afternoon remains low.
