Weekly Outlook: September 8-14, 2025

Much of the upcoming week will be dominated by quiet and cool weather thanks to a large high pressure area.

The cold front that produced severe weather on Saturday and a cool but beneficial rainfall on Sunday has pushed offshore and high pressure will build in bringing drier air in along with temperatures that are below normal for today and Tuesday. Things could get a little complicated for part of the region for Wednesday. An area of low pressure will pass well offshore, but the precipitation shield around the edge of the system could get close to parts of the South Coast, possibly even a little farther northward. However, the high to the north looks like it may remain strong enough to keep most of the rain offshore, so we’re going to lean towards a dry forecast for now. High pressure returns for the end of the week and start of the weekend. A cold front will move through with little fanfare on Sunday, keeping us dry.

An offshore system may produce some rain across Cape Cod and the South Coast, or maybe it won’t. Images provided by Pivotal Weather.

Weekly Outlook: September 1-7, 2025

Happy Labor Day and welcome to September. It marks the unofficial end of summer and the official start of meteorological autumn. College football is underway, the pros start this week, hockey training camps start up in a couple of weeks, pumpkin everything is available everywhere, and after a cool August, warmer weather will return for a few days this week.

High pressure will keep us dry for the first half of the week, likely right into Thursday, but with an upper-level low nearby, we’ll still have some afternoon clouds each afternoon. Temperatures will be close to normal for early September to start the week, but as the high slides offshore, southwest winds will bring warmer and eventually more humid air in towards Wednesday and Thursday. A slow-moving cold front will move in Thursday night, with some showers and a few thunderstorms likely on Friday. With the front taking its time, Saturday may also be a warm and humid day, with the potential for some additional showers or thunderstorms, depending on when the front actually moves across the region. High pressure should build in behind the front for Sunday with cooler and drier weather, just in time for the Patriots home opener in Foxborough.

We’re not expecting a lot of rain with the cold front at the end of the week, but every little bit helps as the drought worsens. Images provided by Pivotal Weather.
