Forecast discussion: Despite a high pressure system over eastern Canada, an upper level disturbance is passing over New England. This disturbance is helping to create the flurries and snow showers over eastern Massachusetts. Over the last 2 hours, the activity has moved south into central Rhode Island and into Plymouth County, as well as Cape Cod. This activity will continue for several more hours, until the disturbance moves off to the east. Some isolated areas could see an inch of snowfall from snow squalls or light snow.
The high pressure center will be over the area by tomorrow. So, winds will be turning calm, especially by early Friday morning. Also, winds will be turning from the cold northeast direction to a warm southwest direction. You will notice a dramatic difference in our temperatures on Friday afternoon, as the mercury climbs near 40 degrees. By Saturday, temperatures will actually reach normal conditions for this time of the year.
A cold front will come down from eastern Canada, and also provide us with some possible snow showers late Saturday night into Sunday. However, the snow showers will end before noon, with mostly sunny skies expected before sunset. Let me remind everyone that we turn our clocks ahead one hour Sunday morning at 2 a.m.
The next chance for any precipitation will be Monday, when a weak cold front will give us the chance for a possible mix of rain and snow showers in the morning. The precipitation should change to rain, but all precipitation ends by the middle of the afternoon. High pressure will bring drier weather for Tuesday, before a slow moving cold front will bring some rain and/or snow showers Wednesday. There may be enough cold air in the lower levels of the atmosphere to make this a wet snow, not the fluffy, dry snow we have seen in earlier snow storms. You will notice our high temperatures are not very cold, but are still slightly below normal.
