Cincinnati is starting today, under fog and mist, with temperatures around 70 degrees and visibility near five miles at the Lunken station. The murky morning should give way to mostly sunny skies, but the afternoon will turn hot, humid, and increasingly stormy.

Fog Burns Off Before 90-Degree Heat

The National Weather Service office in Wilmington expects a high near 90 degrees, with heat-index values reaching about 100. A southwest breeze will stay light at roughly 3 to 8 mph, while a 30% chance of showers and thunderstorms arrives after 3 p.m., with only light rainfall expected in most spots.

Storm chances continue into Saturday evening, with a 40% chance of showers and thunderstorms through midnight before skies turn partly cloudy. No watches or warnings are currently posted for the Cincinnati region, but outdoor plans should include a backup for lightning and a quick downpour.

Sunday And Monday Stay Sunny And Hot

Tomorrow looks quieter and sunnier, though temperatures will still climb to around 91 degrees. Monday, August 10, may be the hottest day of the stretch, with a high near 92 and mostly sunny skies; overnight lows will remain warm in the low to mid-70s.

Storm Chances Grow Midweek

The pattern turns more unsettled Tuesday, August 11, with a 40% chance of showers and thunderstorms and a high near 91. Storm chances rise sharply Tuesday night into Wednesday, August 12, when showers and thunderstorms are likely, and the high reaches about 87.

The National Weather Service forecast discussion warns that multiple rounds from Monday through Wednesday could bring damaging wind and flash-flooding concerns, though the exact timing and location remain uncertain. Thursday stays storm-prone with a 60% chance of rain and thunderstorms, while Friday, August 14, brings a cooler high near 83 and a 50% chance of showers and storms.
