Connecticut Weather: Thunderstorms In The Forecast Today, Details On Timing

It’s becoming more likely than not that Connecticut will see a round of showers and thunderstorms this afternoon and evening, and the stubborn clouds will stick around Sunday morning before lifting and allowing the sun to take over in the afternoon.

The National Weather Service has issued a "Hazardous Weather Outlook" for Hartford and Tolland counties for thunderstorms this afternoon. The entire state may see thunderstorms this evening, especially before midnight.

If you have outdoor plans this evening you will want to be prepared for fast-moving storms that could drop heavy rain in a short-period of time. NBC Connecticut Meteorologist Josh Cingranelli‏ wrote, “Another round of T-Storms this evening. Details on how it could impact holiday plans right now on NBC CT.”

Once the storm threat ends tonight the rest of the 4th of July holiday period looks good except there is now a chance for thunderstorms Monday afternoon as temps will approach 90 degrees. (To sign up for free, local breaking news alerts from more than 100 Connecticut communities click here.)
