Astronomical summer begins this coming Sunday at 4:24AM, but summer weather will be here for much of the week.

We start off the week with a cold front pushing offshore this morning, taking the last of the showers and thunderstorms with it. Behind that front, high pressure builds in with seasonably mild temperatures, lower humidity, and a good amount of sunshine for today and Tuesday. By Wednesday, we’ll be watching a low pressure area heading into the Great Lakes. It will send a warm front our way at night, with some clouds moving in ahead of it, but the day itself will be mostly dry and seasonably warm. A few showers and thunderstorms may accompany the warm front Wednesday night, but the more noticeable effect will be an increase in humidity levels once again. Thursday could be an active day as low pressure moves into southern Canada, dragging a cold front across the region. With a warm and humid airmass in place, the front could trigger showers and thunderstorms during the daytime, with the potential for some of them to become strong to severe later in the day. Right now it’s just potential, but the ingredients are forecast by some of the models to be in place for some severe storms. This is something we’ll be keeping an eye on over the next few days. High pressure builds in behind the front with cooler and drier conditions for Friday and the weekend.

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.

Thursday night: Partly cloudy, any showers and thunderstorms taper off and end during the evening. Low 65-72.

Friday: A mix of sun and clouds, chance for a widely scattered shower or thunderstorm in the afternoon. High 86-93, cooler across the South Coast and Cape Cod. Coastal areas from Boston northward may turn cooler in the afternoon.

Friday night: Partly cloudy with a few showers and thunderstorms expected, skies start to clear out late at night. Low 63-70.

Saturday: Sun, sun, and more sun, much less humid. High 84-91, cooler across Cape Cod.

Saturday night: Clear to partly cloudy. Low 61-68.

Sunday: Sunshine slowly fades behind increasing clouds, breezy. High 85-92, cooler across Cape Cod.

Sunday night: Partly to mostly cloudy with a few showers and thunderstorms. Low 60-67.

Monday: A mix of sun and clouds. High 77-84.

Heat and humidity remain in place to start the week, but they won’t last too long.

High pressure sits offshore today while a cold front begins to approach from the west. That’s a recipe for hot and humid conditions across our region today. We could see a few showers and thunderstorms pop up during the afternoon, but they should not be widespread. Tuesday is the transition day, though it will be very warm to hot and quite humid once again. Across parts of southeastern Massachusetts and Cape Cod there is the potential for some heavy downpours early in the day as what’s left of Tropical Storm Chantal moves past the area. Later, that cold front will move across the region, resulting in more widespread showers and thunderstorms, a few of which could be strong to severe across the interior.

The front settles south of the region, but likely remains close enough for plenty of clouds on Wednesday with cooler temperatures and possibly a few showers as well. A wave of low pressure riding along the front brings in more showers for Thursday. For Friday, a few lingering showers are possible, but some drier air will start to move in as high pressure starts to build in across southeastern Canada. Saturday should be mostly dry, but with an upper level low pressure area moving through we’ll see some clouds and possibly a shower or two in the afternoon. High pressure should move offshore for Sunday with dry and warmer weather expected.

A few models show the potential for heavy rain near the South Coast Thursday, but many show nothing more than scattered showers. Images provided by Pivotal Weather.

Tuesday: A mix of sun and clouds, humid, showers and thunderstorms likely in the afternoon, a few could be strong. High 85-92, cooler across Cape Cod.
