Mid-week muggy, showery surge gets swept seaward, autumnal taste arrives

Dave Hayes maintains a daily blog on Facebook (facebook.com/WesternMassWeather), where he produces hyper-local reports, answers questions, and keeps more than 34,000 followers informed and educated about the weather.

Hello and good day to you, residents of Windham County! I hope things are well with you. The next seven days of our local, sensible weather looks lovely, overall. However, we do have a warm, muggy, breezy, and possibly thundery day for Wednesday afternoon and evening.

This activity will develop in response to an incoming cold front and the associated humidity surge preceding it.

By Thursday, aside from a few clouds or showers on Friday from the passage of Hurricane Dorian well southeast of our region, we’ll enjoy much drier and cooler air and calm conditions through the weekend into early next week before we warm up by the middle of next week.

If you know folks in Nova Scotia, alert them that they’ll likely be hit by Dorian on Saturday, which should be a Category 1 hurricane or strong tropical storm transitioning to an extra-tropical gale.

Having painted our comparatively calmer weekly weather picture, let’s jump into the daily details!

For Wednesday, we should start with some morning patchy fog. Thereafter, we’ll transition to a partly sunny to mostly cloudy day, with clouds building especially in the afternoon.

A high-pressure system will be positioned to our southeast, which will develop a southwesterly, muggy flow into the region. This moist flow will push dew point temperatures into the 60s to near 70 degrees — truly a late-summer day with highs well into the 70s.

Ahead of this front, a line of showers, downpours, and thunderstorms should form in the later afternoon and early evening. A couple of storms may become strong to severe with torrential rain and localized damaging wind gusts, but cloud cover might prohibit severe weather from developing.

Lows Wednesday night will plummet into the upper 40s to low 50s as cooler, drier Canadian air thoroughly overspreads the region by Thursday.

For Thursday, high pressure builds into the region, and we’ll enjoy mostly sunny skies, much drier air, and highs in the mid 60s to low 70s. Lows will bottom out in the upper 40s under partly cloudy skies.

For Friday, we have to watch Dorian. As of this writing, it is forecast to track northeast away from the North Carolina coast and pass 75 to 100 miles south of Nantucket on its way to slam eastern Nova Scotia as a weaker but still formidable storm.

This could bring some clouds to our region, and even a few showers in southeastern Windham County. Highs will be in the low to mid 60s with lows in the 40s with a mix of sun and clouds.

Saturday through Tuesday looks like a beautiful stretch!

Except for a passing shower in the mountains over the weekend, we should enjoy partly to mostly sunny skies during this period, with highs of 60-65 degrees and lows of 42-47 degrees in the high terrain.

We can expect highs of 65-72 degrees and lows of 45-50 degrees in the river valleys. A taste of early autumn is on the way! Have a great week!
