CT Weather: Strong-To-Severe Thunderstorms Forecast: Timeline, New Details Released

CONNECTICUT — Summer-like weather is coming to the state this week, and there is a chance for strong-to-severe thunderstorms on Thursday afternoon, according to local forecasters.

While wet weather is expected to linger into Wednesday, Connecticut will start to experience “drier, hotter and more humid” weather starting Wednesday afternoon, according to WFSB.

WFSB meteorologists expect the heat and humidity to peak on Thursday, calling the Juneteenth holiday a “First Alert Weather Day.”

Thursday’s storm details

“Storms will be possible in the afternoon and early evening hours as a cold front arrives and could reach strong to severe levels,” according to WFSB. “Lightning, heavy rainfall, damaging wind gusts, and hail will be the top threats. Given the heat, humidity, and storm threat Thursday it is a *First Alert Weather Day* as outdoor plans could be impacted.”

Both Wednesday and Thursday will bring a chance for thunderstorms, according to the National Weather Service.

Weekend forecast details and a heat wave is on the horizon

The early weekend is predicted to be dry and “comfortably warm,” according to WFSB.

The first heat wave of the year is expected to come on Sunday, WFSB reports. The National Weather Service predicts temperatures will reach into the upper 80s on Sunday.

WFSB is calling Monday another “First Alert Weather Day” with temperatures reaching “near-record” levels, and higher humidity. WFSB meteorologists say heat index values “could top 100” come Monday. (Read more at WFSB 3 TV).

The National Weather Service predicts temperatures in Connecticut could reach about 90 degrees in the southern part of the state, and up to 94 inland on Monday, with sunny skies.
