Cleveland is starting Wednesday clear and muggy, with temperatures climbing quickly toward a hot afternoon peak. The city could reach 91 degrees, while the heat index rises as high as 99 before rounds of showers and thunderstorms return.

A Heat Advisory remains in effect through 8 p.m. Wednesday, with heat-index values expected to reach the upper 90s to near 102 across parts of the region, according to the National Weather Service. Officials recommend lightweight clothing, frequent breaks in shade or air conditioning, and extra attention to children, older adults and anyone working outdoors.

Storm Chances Return In Waves

The first chance for storms arrives Wednesday morning, followed by a break that should allow temperatures to surge through the afternoon. Another round is possible late Wednesday afternoon and evening, with the strongest storms capable of damaging wind gusts, small hail and brief heavy rain.

Forecasters say an isolated tornado cannot be ruled out, though that threat is considered low. Storms may continue into the overnight hours, and persistent downpours could create isolated flooding issues before activity pushes southeast around midnight.

Thursday Brings More Rain And Some Relief

Thursday should be cooler, but not exactly crisp, with a high near 85 and showers and thunderstorms likely early in the day. Rain chances remain elevated into the afternoon and evening as a slow-moving cold front crosses the area.

Thursday night could stay stormy, with a 70% chance of showers and thunderstorms and a low around 72. Friday remains unsettled as well, with storms likely before 2 p.m., mostly cloudy skies and a high near 82.

Weekend Forecast Turns Drier

Conditions should settle down Friday night into the weekend as temperatures ease back toward seasonal levels. Saturday brings mostly sunny skies, a high near 79 and only a slight chance of a rain shower before 2 p.m.

Sunday looks like the best outdoor day of the stretch, with sunshine and a high near 77. Labor Day should stay mostly sunny near 80, although a slight chance of afternoon showers returns; the latest update is a substantive shift from Hoodline's earlier Cleveland forecast because the new outlook adds the heat advisory and a sharper severe-weather concern.
