Connecticut forecast turns hot and humid with afternoon storm risk

Friday in Connecticut is expected to bring another hot, humid day, with temperatures mostly in the upper 80s and heat index values reaching the mid-90s in many areas.

A cold front is expected to move in later in the day, increasing the chance of thunderstorms during the afternoon and evening. CT Insider reported that the main concerns are lightning and slow-moving heavy downpours, which could lead to localized street flooding if storms repeat over the same area.

Timing and impact

The day is expected to start with the strongest heat building before storms become more likely later on. The southeastern shoreline may stay a bit cooler, closer to 80 degrees, while inland Connecticut and the Litchfield Hills are still expected to feel hot and humid.

No watches or warnings had been issued for Connecticut at the time of publication.

Broader pattern

The forecast fits a stretch of summer heat and humidity across the state. CT Insider also reported Thursday that elevated ozone was affecting air quality in southern Connecticut, another sign of the hot, sunny conditions.

The weekend outlook turns more comfortable, with Saturday still humid and Sunday expected to be less humid and sunnier.

Residents planning outdoor events Friday should be prepared for sudden weather changes, especially during the afternoon and evening storm window.
