Wilmington, Ohio – Strong to severe thunderstorms are expected to develop across much of Ohio Saturday afternoon and evening, bringing the potential for damaging wind gusts, torrential rainfall and isolated flash flooding. The greatest threat is expected between 3 p.m. and 10 p.m., when storms are forecast to sweep south across the region.
According to the National Weather Service in Wilmington, showers and thunderstorms will become more widespread during the afternoon as a weather system moves through the Ohio Valley. While not every community will experience severe weather, a few storms could become strong enough to produce damaging winds, the primary hazard with this event.
The severe weather outlook places much of central and southwest Ohio, including Columbus, Dayton, Wilmington, Chillicothe and surrounding communities, under a Level 2 of 5 (Slight Risk) for severe thunderstorms. Farther south, including portions of the Cincinnati metro, the threat drops to a Level 1 of 5 (Marginal Risk), though isolated severe storms remain possible.
In addition to damaging wind gusts, thunderstorms will be capable of producing locally heavy rainfall, which may lead to isolated flash flooding in low-lying and poor drainage areas. Forecasters note there is still some uncertainty regarding the exact timing of storm development, but conditions could change rapidly once storms form.
Residents should have multiple ways to receive weather warnings, secure loose outdoor items before storms arrive and avoid driving through flooded roadways. Additional watches or warnings could be issued Saturday as confidence increases in the storm track and intensity.
