Scattered Showers Arrive Tuesday Night

The week starts off dry, thanks to high pressure overhead. But by Tuesday evening, things start to change as that high drifts offshore and lets in moisture.

When and Where to Expect Rain

There’s a 20–30% chance of showers kicking off Tuesday night. That bumps up to about 50% for Wednesday and early Thursday. Folks in northern Connecticut—think Windsor Locks, Enfield, Suffield—might even hear some thunder as isolated storms pass through.

Rain could mess with outdoor plans, but there should be plenty of dry breaks. It’s definitely not going to be a steady downpour.

Midweek Temperatures: Mild with a Cool Edge

Temperatures will run just a bit below typical mid-August highs around midweek. Most towns will see afternoons in the low to mid-70s.

Places along Long Island Sound—Branford, Old Saybrook, Milford—might feel a little cooler, thanks to the breeze coming off the water.

Shoreline and Inland Differences

On Wednesday and Thursday, inland spots like Danbury and Manchester will be a touch warmer. Meanwhile, shoreline towns get those crisp breezes and milder temps.

Thursday Brings Brighter Skies

By Thursday afternoon, the unsettled stretch should wrap up. Skies clear out, and sunshine returns across Connecticut.

Highs will bounce back toward the upper 70s. In the Connecticut River Valley—Middletown, Wethersfield—80 degrees isn’t out of the question.

Perfect Weather Ahead for Friday

Friday’s looking fantastic: lots of sun and highs in the low 80s. There’s a change coming Friday night, though, as the air starts to feel different.

Fall Preview for the Weekend

A cold front late Friday brings in a real autumn vibe. Saturday morning lows will hover near 50 degrees, which might have early risers in Litchfield or Torrington reaching for a light jacket.

With plenty of sun, afternoon highs only reach the lower 70s. Not a bad setup for farmer’s markets, fairs, or just wandering around town.

Sunday Morning Chill

Sunday morning dips even cooler, with some spots—especially in rural Windham County—dropping into the upper 40s. Still, the day warms up nicely into the lower to mid-70s.

That’s about perfect for anything outdoors in Cheshire, Groton, or Simsbury.

Extended Outlook: Comfortable Late Summer Days

The National Weather Service says we’re in for mostly sunny and seasonable weather from Friday through Monday. Highs each afternoon should land between 72 and 78 degrees.

It’s a great stretch for late summer hiking, beach walks along the Connecticut shoreline, or just hanging out in the backyard. Honestly, it feels like the kind of weather we wait all year for.

Key Takeaways for the Week

Here’s what Connecticut residents can look forward to:

Scattered showers and a chance of thunderstorms late Tuesday night through early Thursday.
Temperatures will hang out in the low to mid-70s midweek. It might feel a bit cooler if you’re near the shore.
Thursday afternoon and Friday look brighter and warmer.
The weekend brings crisp, sunny weather. Lows will dip into the upper 40s or near 50, and highs should reach the low 70s.
Most of early next week stays mostly sunny, too.

From Stamford’s busy streets to the quieter spots in Bethel, Connecticut’s weather feels like a mixed bag this week. Keep an umbrella handy midweek, but honestly, it’s hard not to get excited for that classic, fall-ish weekend coming up.
