Forecast discussion: Well, we had snow for several hours early Tuesday morning in eastern Massachusetts, before we changed over to sleet and rain during the afternoon. Middlesex County did see the most snowfall, with Townsend seeing almost 14 inches, before the changeover. South Boston saw 8 inches, while Bristol County only reached 4 inches.
We should see mostly sunny skies on Wednesday, as a high pressure ridge begins to build over New England. However, the low pressure system will still be moving out of the Gulf of Maine, so winds will increase, especially in the afternoon. However, winds will begin to decrease, as the high pressure centers moves closer to Southern New England. Also, we will welcome the vernal equinox, or astronomical spring, at 7:02 a.m. Wednesday morning.
However, although it is spring on the calendar, it may not look like spring on Thursday. A weak area of low pressure will remain over the Delmarva Peninsula. Although a much stronger low will move offshore, this area will help create some snow showers throughout the day. I am not expecting any snowfall accumulations, as there will be no strong upper level dynamics with this moisture. The snow showers will end before midnight.
We may see a passing shower Friday afternoon, as a weak low pressure center moves into New England. Once the low passes to our east, high pressure will build in for the weekend. Temperatures, however, will remain below normal, as normal temperatures should be in the upper 40’s for this time of the year.
As we move into early next week, another developing low pressure system over the Southeast U.S. will bring another chance for some rain and snow showers on Monday. However, this low will be moving offshore, and into the Atlantic by Monday evening. We should see more clouds than sunshine next Tuesday.
