Cincinnati is waking up to a warm, sticky start, with mostly cloudy skies and temperatures already near 75°F at Lunken Airport. By this afternoon, the mercury is expected to push into the upper 80s to around 91°F, and the humidity will make it feel more like the upper 90s to about 101°F. Scattered showers and thunderstorms could pop up during the day, with a more organized line of storms expected to roll through overnight ahead of a cold front.

Afternoon Heat And Storms

A Heat Advisory is in effect for parts of west-central Ohio from noon to 8 p.m., while the rest of the forecast area, including much of the Cincinnati metro, is covered by a Special Weather Statement highlighting heat index values as high as 95–101°F today, according to NWS Wilmington. The forecast high for Thursday, June 11, is near 91°F, with about a 30–40% chance of showers and thunderstorms this afternoon. Any storms that bubble up are likely to be brief but could deliver heavy rain and gusty winds.

Tonight And The Weekend

Widespread showers and thunderstorms are expected to move in tonight ahead of an approaching cold front, and a few strong to severe storms are possible, with damaging winds as the primary hazard. The front is expected to move east of the area by Friday morning, bringing drier and slightly cooler air for Friday and Saturday. A secondary front late Saturday into Sunday will bump storm chances back up, with cooler conditions settling in early next week.

Beat The Heat

For anyone needing a break from the heat, Cincinnati recreation centers and spraygrounds are open, and some locations are serving as cooling centers. Check hours and locations on the City of Cincinnati website. Common-sense moves still matter: drink plenty of water, limit strenuous outdoor activity between noon and 8 p.m., and never leave children or pets in parked cars. It is also a good idea to check the radar and updated forecasts before heading out this evening.

Consider afternoon plans flexible: shift events earlier or later if you can, and have a backup shelter spot in mind if storms develop. Forecasts and any watches or warnings will be updated as conditions change.
