Severe Weather Forecast This Weekend In CT: Here's When, What To Expect

The first half of the weekend is expected to be stormy, with thunderstorms and heavy rain possible.

The National Weather Service predicts Saturday will bring an increasing risk for thunderstorms “capable of torrential downpours.”

Timeframe for storms

The likeliest timeframe is Saturday afternoon and into the overnight hours, and there will be the potential for street flooding, according to the National Weather Service.

The risk for severe weather is higher in southern Connecticut Saturday, where a hazardous weather outlook is in effect.

“Showers and thunderstorms are expected Saturday into Saturday evening,” the outlook says. “There is a slight risk for severe thunderstorms with the main threat damaging wind gusts. An isolated tornado cannot be ruled out. Heavy rainfall is also possible which may lead to isolated to scattered flash flooding."

WFSB is calling Saturday a “First Alert Weather Day,” due to the anticipated stormy weather in the afternoon and evening.

“While we certainly need rain, this round is poorly timed as it could impact outdoor activities, especially with a threat for stronger storms also in the mix through the afternoon and evening,” WFSB reports. “Poor drainage flooding will be possible in areas that see repeated downpours.”

WTNH says it is watching a “strong weather system for Saturday & Saturday night with some showers and storms.”

It predicts some storms could be “strong to severe along with a brief flash flooding risk.”
