Cincinnati is starting today under fog and mist, but the gray opening should give way to a mostly sunny afternoon near 85 degrees. Rain is not expected, and a light north wind of 1 to 5 mph should keep the day fairly quiet.

The forecast stays comfortable by late-summer standards tonight, with mostly clear skies and a low around 63. Saturday will be sunny and a little warmer at 87, with only a light east breeze. According to the National Weather Service, the dry stretch should hold through at least Tuesday.

Heat Builds Quickly Next Week

Sunday climbs to 92, followed by highs near 95 Monday and 96 Tuesday. Compared with the previous Cincinnati forecast, the latest outlook pushes the heat higher and extends the hottest stretch into Wednesday.

Humidity is expected to rise as southerly flow develops early next week, and heat-index readings could reach the mid to upper 90s. Anyone planning outdoor work or long stretches outside should aim for cooler morning or evening hours and stay on top of hydration.

Storm Chances Return Midweek

Wednesday brings a slight chance of showers and thunderstorms after 2 p.m., with a 30% chance Wednesday night. Thursday could see a few morning showers followed by another slight storm chance, while the high remains near 95.

No watches, warnings, or advisories are listed for the Cincinnati-area forecast at this time. The best bet for dry outdoor plans is Friday through Tuesday, before the small but growing storm chances arrive Wednesday and Thursday.
