Cincinnati is waking up to a steamy setup for storms. Lunken Field reported hazy skies and about 73°F early this morning, July 21, with a line of storms expected to roll in by mid-to-late morning. The main window for heavy rain runs roughly 9 a.m. to 3 p.m. The high should reach near 88°F, but pockets of heavy downpours and gusty winds could make roads slick and outdoor plans a headache across the Tri-State.
Storm Timing And Threat
The National Weather Service is calling for a chance of showers and thunderstorms between about 8 and 9 a.m., then more widespread storms from late morning into the afternoon today, July 21, with the best coverage along and southeast of the I‑71 corridor, according to the National Weather Service Wilmington office. Most areas will see southwest winds of 5 to 12 mph and a high near 88°F, but thunderstorms could drop heavy rain at rates of roughly three-quarters to one inch in a single storm and kick out locally damaging wind gusts.
Forecasters say the severe threat is conditional, but the setup does include the risk of damaging wind and isolated large hail in the stronger cells. Behind the front, surface high pressure builds in, ushering in drier, cooler air for midweek with highs returning to the upper 70s tomorrow and Thursday.
Flood Watch And Travel Impacts
A Flood Watch is in effect for portions of the forecast area this afternoon into the evening, and localized flash flooding will be possible where storms train or stall over the same spots. Drivers are urged to avoid plowing through standing water. Recent storms have flooded low-lying sections of I‑71 and other routes, leading to road closures and water rescues, and similar trouble spots could flare up again. Expect delays for the evening commute if storms are still in the area.
If you experience basement flooding or sewer backups, report it to the Metropolitan Sewer District at (513) 352‑4900 or online so crews can respond. Keep an eye on local alerts, and move outdoor activities indoors while storms are active.
Tonight And The Week Ahead
There is a chance of lingering showers and thunderstorms early this evening, then skies should trend partly cloudy with a low near 66. Tomorrow and Thursday look drier and cooler, with daytime highs in the upper 70s, before temperatures climb back toward the 80s and 90s later in the weekend with renewed storm chances. Check updated forecasts and local alerts before traveling or locking in outdoor plans later this week.
