Cincinnati weather: Area under flood watch until Wednesday. What to know

Several rounds of showers and thunderstorms will move across the Ohio Valley region Tuesday through Wednesday.

The National Weather Service in Wilmington has issued a flood watch, effective from noon Tuesday through Wednesday evening.

Hamilton, Clermont, Butler, and Warren counties in Ohio, Campbell, Kenton, and Boone counties in Kentucky, and Dearborn, Franklin, Switzerland, and Ohio counties in Indiana are under the watch.

Thunderstorms will have the potential to produce damaging winds Tuesday afternoon and into the evening hours. Flash flooding caused by excessive rainfall will be possible.

Excessive runoff may flood rivers, creeks, streams, and other low-lying and flood-prone locations. People in the watch area, especially those living in areas prone to flooding, should be prepared to take action. Make sure to monitor the latest NWS forecasts and be alert for possible flood warnings.

The combination of heat and humidity will also lead to heat index values near 100 degrees across the far southern portion of the region on Tuesday.

Cooler temperatures and drier conditions will begin on Wednesday as a cold front moves into the area. Temperatures are only expected to be in the 70s to low 80s.

The dry spell will continue through the end of the week. On Thursday, temperatures will be several degrees below normal, with highs in the 75- to 80-degree range.
