Very warm to hot weather will continue through the weekend, but the humidity won’t.
High pressure anchored off the East Coast will continue to pump hot and humid air into the region on southwest winds for another day or so, but some relief is on the way. A few showers and thunderstorms are possible through the evening, but they should gradually dissipate, leaving us with a warm and muggy night. Friday will also be hot and humid for most of the region, but a backdoor cold front will slip down the coast, bringing relief to coastal portions of Maine and New Hampshire, as well as the North Shore and likely the Boston area by midday. It probably won’t get too far inland, and may not get to the South Shore, but behind that front, temperatures will be in the 70s and lower 80s, compared to upper 80s and lower 90s inland. The South Coast and Cape Cod will be cooler as well, with southwest winds acting as a seabreeze. There could be a few widely scattered showers and thunderstorms in the afternoon, but most of the region will remain dry.
A stronger cold front moves in from the west Friday night, producing a few more showers and thunderstorms overnight. Behind that front we’ll clear out on Saturday. It will remain quite warm, with most places getting well into the 80s, but humidity levels will be much lower. Some clouds will start to filter back in on Sunday as another front moves toward the region, but again, most of the day will be dry and very warm. That front may produce a few showers and thunderstorms Sunday night, then we’ll see drier and cooler weather return for Monday.
