Forecast discussion: The low pressure system that brought Atlanta, GA to a standstill on Tuesday brought some light snow amounts to Boston and the rest of eastern Massachusetts. One to two inches fell in the Boston area, while anywhere between three and seven inches fell on Cape Cod and the Islands.

High temperature forecast for Jan. 30, 2014

With that system well into the Atlantic, a strong high pressure system over West Virginia will bring us dry weather for the next 36 hours. We will still see bitterly cold temperatures tonight, with some warmer air arriving on Thursday. High temperatures will actually be near freezing. By tomorrow night, cloud cover will actually keep the sun’s energy from escaping back into space. Low temperatures Thursday night will be about 10 degrees warmer than the previous night.
As we begin the weekend, a weak warm front will pass through New England. It may help create some isolated showers Friday afternoon, during the evening commute. A possible snow shower could come early Saturday morning. However, as the weak cold front passes, it may help create some showers Saturday afternoon. We will see a greater chance at precipitation during Sunday afternoon, as a low pressure system from the Southeast U.S. passes through New England.

Our temperatures will return back to seasonable conditions on Monday, as high pressure brings mostly sunny skies. As I watch the long range models, the American model continues to form a strong low pressure system along the eastern coastline Monday evening. The low will remain to our north and west, which means we will be in the warm sector. So, we would see a mix of rain and snow showers early Wednesday morning, before changing to rain. Heavy rain would fall Wednesday afternoon, but a strong cold front passing through may change the precipitation back to snow showers. It would remain snow showers for the last few hours, before the precipitation moves offshore. At this time, none of the other models are showing a strong low, so my confidence in the forecast after Tuesday afternoon remains quite low.
