Midweek Cold Front Brings First Real Taste of Fall

This Wednesday, a cold front will sweep through Connecticut and finally end that stretch of 80-degree days. Daytime highs will tumble, with most spots only making it into the 60s.

High pressure will settle over the Northeast after the front moves through. Expect sunny skies and that classic, crisp, dry feel right through the end of the week.

Even though Hurricane Humberto will stick to the ocean, hundreds of miles offshore, it’s still going to have a say in our weather. The pressure gradient will tighten, kicking up gusty winds—especially along the shoreline.

Wind speeds could hit 15 to 30 mph in places like New London, West Haven, and Bridgeport. Inland towns such as Middletown and Manchester will feel some breezes, but they probably won’t get the full brunt like the coast.

Cool Nights Ahead for Northern Hill Towns

The chill will really settle in overnight Thursday and Friday. Many towns north of Hartford could see lows in the 40s, and spots like Litchfield, Winchester, and Norfolk might even dip into the 30s.

If you’re a fan of autumn nights, this is your moment. It’s perfect for evening walks under the stars or finally breaking out that first cup of hot cider.

Regional Temperature Forecasts

Here’s what the models are showing for Thursday and Friday:

Shoreline towns—Stamford, New London, Madison: 62–67 degrees
Inland spots like Waterbury, Manchester, Middletown: 62–66 degrees
Litchfield Hills: 60–65 degrees

Breezes will hang around, and the dry air and sunshine should keep things feeling bright, even if it’s not quite as warm as last week.

Weekend Warm-Up: A “Third Summer”

This cool spell isn’t sticking around. Forecasters see a surge of warm, southern air heading our way by Saturday.

Temperatures could jump back near 80 degrees for much of Connecticut, giving us that so-called third summer right at the start of October.

Perfect Weather for Outdoor Plans

From coastal New Haven to inland Danbury, expect dry, sunny skies this weekend. It’s ideal for apple-picking in Glastonbury or a stroll on the Milford boardwalk.

Overnight lows will be milder too, mostly holding in the 50s.

Looking Ahead: Dry Conditions Continue

Dry weather looks set to stick around through at least the middle of next week. If you’ve got outdoor projects or community events in places like Norwalk, Stamford, or Hartford, you can probably count on clear skies for a while.

But if this dry stretch keeps going, it could start to worry local farmers, especially with autumn planting and harvesting in full swing across the state.

Summary for Connecticut Residents

In short, residents can expect:

Wednesday: Cold front arrives. Highs in the 60s, with gusty winds around 15–30 mph.
Thursday-Friday: Sunny days ahead. Cool nights drop into the 40s, or even the 30s in Litchfield Hills.
Saturday-Sunday: Temps warm up near 80 degrees. Air stays dry.
Early next week: Still dry and mild across the state.

Maybe you’re in Hartford’s lively downtown, or you’re out in the hills of Litchfield, soaking in the leaves. Connecticut’s October weather seems to toss us a bit of everything—some winter chill, a touch of summer warmth, all packed into one wild week.
