We end the week with sun and clouds this afternoon, highs between 80 and 85.

The weekend: heat and humidity will be on the increase. There is a chance for a late day storm Saturday, into Saturday night. There will be another chance for isolated to scattered storms Sunday.

Sun, Mon, Tue, Wed… highs could reach/exceed 90, so we’re currently forecasting a 4 day heat wave (it could last longer).

Past the weekend, a more substantial chance for rain/storms comes late Tuesday into Wednesday of next week.

Today will be another winner, another top ten best day of the year! High pressure will hug the coast of New England and that means we’ll enjoy another day of abundant sunshine. Highs will be in the low and middle 80s. Temperatures should remain in the 70s along the beaches in New London County since an onshore breeze will freshen as the day progresses. The humidity will be a little higher, but still in the comfortable range.


Temperature and humidity levels will be on the rise this weekend. Saturday won’t be too bad with partly sunny skies and highs in the mid to perhaps upper 80s. However, Sunday will be hotter with highs in the lower 90s away from the coast. The air will be humid and the sky will be partly to mostly sunny. A shower or thunderstorm can’t be ruled out at some point over the weekend, especially Saturday night and Sunday morning. With that said, our weather should be mainly dry for outdoor events and there will be some big ones! We have the Fireworks Extravaganza at Sailfest in New London Saturday evening at 9pm. We also have Riverfront Fireworks in Hartford Saturday evening at 9pm.

The hot weather is expected to continue Monday, Tuesday, and Wednesday with temperatures reaching or exceeding 90 degrees. That means we could have our second heat wave of the year! At this time, we are forecasting a 4-day heat wave, but it could last longer. There is also a chance we won’t reach 90 degrees on Tuesday if a front sends clouds and showers our way earlier in the day. At this point, it looks like showers and thunderstorms will hold off until the afternoon and evening hours on Tuesday. Other than that chance for showers and t'storms Saturday night and Sunday morning, Tuesday will be our best chance for rain over the next 7 days. We really need some rain since much of Northern and Eastern Connecticut is considered to be abnormally dry.

Showers could linger into Wednesday morning, and then the sky should become partly to mostly sunny. The air will turn a little less humid. Thursday is expected to be a mostly sunny day with highs in the upper 80s, but we may have a shot at 90 degrees. We’ll see!
