Forecast discussion: After a cold front passed through eastern Massachusetts this afternoon, skies began to clear and we had mostly sunny skies over Boston. For this evening, the high pressure ridge will move over the state this evening, giving us clear skies and calm winds. This will help lower our temperatures into the lower 40’s.
The high pressure system will remain over the eastern U.S. for the next few days, and it will stay to our east. This will allow temperatures over the next few days to be quite seasonable. A weak cold front may help some drizzle early Wednesday morning, with a possible shower during the mid-morning. Otherwise, the cold front will pass quickly over New England, and we will return to high pressure Wednesday night.
However, the high will also help bring in the polar air that is going to create below normal temperatures and snow in the northern Central U.S. That dome of cold air will stay eastern Massachusetts well into early next week. High temperatures will only be in the 40’s, with overnight temperatures at or below freezing. Looking ahead to the extended outlook, a developing low pressure system off the coast of North Carolina may bring some snow showers by early Friday morning, but ending by the early afternoon.
As we look ahead to the following weekend, we will see sunny skies but cold temperatures on Saturday, with a possible low pressure system coming up from the Southeast U.S. giving us wintry precipitation Sunday afternoon. At this time, the location of the low will tell us if the precipitation will start off as rain, and then change over to a wintry mix. But, if the low is further to the east, it could be a wintry mix changing over to snow showers. At this time, my confidence in next Sunday’s forecast is quite low, as the models do not agree on the location or intensity of the low.
