Scattered Heavy Downpours, Thundershower Midweek

Hazy sunshine to start the week will fade to clouds, with extreme humidity and a chance for downpours or even a thundershower Tuesday into Wednesday.

A warm front lifts across Connecticut on Tuesday, which means an abundance of clouds. Scattered showers are likely and we could even see some thunderstorms. Temperatures will be in the 80s and humidity will be oppressive.

The atmosphere will be loaded with moisture and winds will be pretty light in the lowest levels, which means flash flooding is a concern.

Currently, it would only take 2-3 inches of rain in a three-hour window to cause flash flooding across the state. Southern New Haven and Fairfield counties are most vulnerable to flooding simply because it would only take 2 inches of rain in a three-hour period there.

Wednesday brings similar weather with oppressive humidity and lots of clouds. Showers will be most numerous in the afternoon, hours before a cold front passes through. Flash flooding will again be possible and the chance of a thunderstorm will increase as the cold front arrives.

The forecast turns murky late week due to uncertainty. Rain and thunder could linger into early Thursday.

There should be more sun later in the week, and it will certainly be more comfortable as humidity levels drop Thursday and Friday.
