Are we in the midst of the best 10-day weather stretch of the entire year? Here are some arguments for making that case. It has been sunny or mostly sunny just about every day for the past week, and it will stay that way through the weekend. The high temperature has been near normal, with a couple of 70° degree days mixed in with mostly 60s. It has been clear and cool at night, with temperatures dropping into the 30s to mid 40s. The sea breezes have been relatively light, meaning that is has not been too cold in the afternoon near the coast. Throw in the fact that the colors are exploding all over the landscape, and there aren’t a lot of bugs out, and I think it’s an incredible stretch of weather. Anyway, how long will it last?
The strong area of high pressure that extends into the Canadian Maritimes will continue to dominate the weather in New England through the weekend. A cutoff upper-level low pressure system will move east from the Midwest into the Southeast by the end of the weekend. It will slowly move northeast, but is not likely to bring showers to Southern New England before Tuesday – at the earliest. Eventually, there will be some showers next week – maybe Wednesday and Thursday. The toughest part of the forecast is trying to figure out if the upper-low will still be capable of producing steady rain when it arrives in New England. If it does, because it is a slow-mover, it may help to cut into the rainfall deficit of late.
At this point, the forecast is for decent weather on Mother’s Day weekend. A cold front that will break the stagnant weather pattern in the Eastern United States will arrive either late in the weekend or on Monday, May 13. That front may bring showers/t-storms and cooler, dry weather right behind it.
