A high pressure system across southern New England will usher in cold and dry weather today, though snow showers are possible over the weekend. Conditions will warm slightly near the end of the weekend, with daytime temperatures cresting in the mid-40s, according to the National Weather Service.
“Tonight there is the risk of ocean effect snow for the outer Cape and Nantucket, but there will be light accumulation,” said Kim Buttrick, weather service meteorologist. “Saturday night there is a chance of snow showers around Boston, but it will change to rain come Sunday morning.”
Today will be mostly sunny, with a high near 33. A northwest wind will develop early in the afternoon, gusting near 15 miles per hour, making conditions feel about 10 degrees colder. Winds will calm near sundown as temperatures drop into the upper teens. Snow showers are possible overnight, but less than an inch should fall, and only over Cape Cod.
The sun will continue Saturday, with temperatures again peaking in the mid-30s. A north wind will blow, but gusts shouldn’t top 5 miles per hour, according to the weather service. Clouds will increase into the late afternoon, and temperatures will fall into the 20s. Snow showers could come to the Boston area overnight, but again, no significant precipitation is expected.
Snow showers will continue into the wee hours of Sunday. But as temperatures warm, the showers will transition into light rain. Sunday will be mostly cloudy, with a south wind gusting near 10 miles per hour. Temperatures will climb into the mid-40s. A few rain showers could pop up overnight Sunday before 1 a.m., and temperatures will fall into the mid-30s.
“Temperatures will moderate on Sunday into the mid-40s, and come Monday, we are looking at highs in the low 40s,” Buttrick said. “It would be Monday night into Tuesday that there could be some scattered rain in Boston, due to an offshore storm.”
