Cool start to week expected for Massachusetts before Thursday downpour
A large high-pressure system over Quebec will bring cooler temperatures to Massachusetts this week, with a chance for heavy rain on Thursday.
It'll be a sunny start to Monday across Massachusetts, with cloud cover growing as the day goes on. High temperatures should range from 50 to 55, with higher elevations seeing temperatures in the upper 40s.
"Winds will not be too bad, though, from the north at 5 to 15 mph," National Weather Service forecasters wrote.
Tuesday and Wednesday look to be more of the same, with temperatures again in the low to mid 50s, and cooler in higher elevations. That said, there is a chance for some ocean-enhanced scattered showers near and southeast of Interstate 95 overnight Tuesday.
"Expect cool, raw and occasionally wet conditions near and southeast of I-95," forecasters wrote.
Forecasters expect a period of heavy windswept rain sometime Thursday into Thursday night, though uncertainty remains about the exact timing and severity of the rain.
The rain is the result of a low-pressure system moving to the west of the region. But Hurricane Melissa, which is set to barrel into Jamaica as a Category 5 storm, could contribute additional moisture as it passes east of New England later this week.
Rainfall of 1 to 3 inches is expected, with the possibility of some nuisance street flooding. Massachusetts could also see winds of 30 to 50 mph, with the strongest gusts near the coast.
Still, the length of the rain may be limited due to the progressive nature of the system, forecasters said.
The exact timing of the system is still unclear, but the rain appears likely to diminish to just a few showers by Friday as a dry slot works its way across the region.
Saturday is expected to be breezy but mainly dry, outside of a spot shower, with seasonable temperatures.
