Forecast discussion: Well, it was certainly warmer than the last few days in eastern Massachusetts today. But, we will not see above normal temperatures until Tuesday. So, we still have to get through a couple more cold days before we see a January thaw.
Also, we will be seeing a little light snow this evening into early Saturday morning. The weak low is forming offshore of the Delmarva Peninsula. It is bringing some snow showers to the southern part of the state at the moment. The light snow should move into eastern Massachusetts by about 10 p.m. The heavier snow will remain offshore, so we are just going to see a coating to an inch in the capital city Saturday morning.
We will see warmer temperatures during the evening hours, as they actually stay in the lower teens. We will finally see our high temperatures go above freezing on Monday. But, we will have to still with some wintry precipitation Monday evening.
A low pressure system will develop in the central U.S. on Sunday. The low will move in a northeast direction, with the precipitation ahead of the low’s center. Despite our warmer temperatures, we will see a combination of rain, sleet, and freezing rain by Monday afternoon. However, a warm front will be moving south of Southern New England Monday night into early Tuesday morning. So, we will see a wintry mix during the overnight hours, but temperatures will actually be rising. So, the precipitation will change to rain before sunrise. Any rain showers will end by the late morning on Tuesday, as temperatures soar into the lower 40’s.
The warm front will linger to our south into Wednesday, but will move through Wednesday night. The front will help trigger some showers Wednesday night, but the precipitation should remain as rain, despite the colder temperatures into Thursday morning. High pressure will slowly build into the eastern U.S. on Thursday afternoon, and will give us drier weather on Friday. However, a cold front will push through on Friday afternoon, with more arctic air returning to the Northeast U.S. Right now, the American model continues to push a second low into the area next Friday, bringing heavy rain, before changing to some possible snow showers Friday night. However, the European and United Kingdom models only have cloudy skies over us. So, for now, I will keep us dry. But, my confidence after Thursday’s forecast remains quite low.
