Thunderstorms Forecast To Help Break Heat Wave: Here's When, What To Know In CT

CONNECTICUT — The heat wave continues on Thursday and Friday, but it appears strong thunderstorms may help break the heat wave in time for the upcoming weekend, according to the latest forecast.

WFSB 3 TV meteorologists said the heat index will make it feel hotter than 100 degrees on Thursday and possibly on Friday.

“As we close out the work week on Friday, a front drops south toward CT and could provide enough forcing for thunderstorms in the afternoon,” WFSB 3 TV meteorologists said. “Given the intense heat and humidity, thus instability in the atmosphere, it will not take much for storms to flare up. Strong storms are possible, and there is even a marginal risk for excessive rainfall…The big question: does our heat wave last 4 days, or 5? The duration is somewhat uncertain given the clouds and rain/storm potential Friday… if we see enough sun, we’ll easily hit/exceed 90; conversely, if storms flare up, temps could peak in the 80s.”

Weekend weather forecast details

“The weekend will remain unseasonably warm, but not *as* hot as what we’re experiencing this week. We’re expecting inland temperatures to top out in the mid-80s Saturday, then upper 80s Sunday; shoreline towns reach 80-85,” WFSB 3 TV meteorologists said. “Overnight temps will again be near 70. Both Saturday and Sunday could also bring some isolated thunderstorms in the afternoon, though the days will be bright otherwise (also continued muggy).” (Read/watch more at WFSB 3 TV).
