Cincinnati woke to fog and mist around 72 degrees Wednesday, but the haze will give way to a dangerous blast of heat. The city is headed for a sunny 98 degrees, with heat index values near 101 and little wind to provide relief.

Heat Peaks Wednesday Afternoon

Temperatures should climb through the 80s late this morning and reach the mid-to-upper 90s from midafternoon into early evening. The heat advisory remains in effect through 8 p.m. Thursday, according to the National Weather Service Wilmington OH.

Thursday will bring another sunny, sweltering day, with a high near 97 and heat index values as high as 103. A slight chance of showers and thunderstorms arrives after 5 p.m., with the potential for strong to severe storms late Thursday into Thursday evening, although confidence is lower farther south and west toward Cincinnati.

Rain Chances Build Friday And Saturday

Friday looks mostly sunny but includes a 30% chance of showers and thunderstorms, especially from late morning into early afternoon. Saturday carries a 40% chance of showers and thunderstorms, with a high near 91; locally heavy rain is possible late in the week, though the timing remains uncertain.

Cooler Weather Arrives Sunday

Sunday brings a welcome reset with sunny skies and a high near 86, followed by a low around 65. Labor Day should stay mostly sunny and warmer, with a high near 87, while Tuesday is forecast to reach 88.

Residents should limit strenuous outdoor activity to early morning or evening, drink plenty of fluids, wear lightweight clothing, and use air conditioning when possible. The weather service also recommends checking on relatives and neighbors, since hot temperatures and high humidity can cause heat illness.
