A Flash Flood Watch has been posted for much of southwestern Ohio and southeastern Indiana, thanks in part to saturated soil after last night’s heavy rain:
While the coverage of showers will be low through mid-evening, scattered showers and thunderstorms will develop late this evening and early in the overnight. There is a risk for strong storms tonight, but the main concern is flooding and flash flooding in the watch area.
The Storm Prediction Center only has communities northwest of Cincinnati in the marginal risk for severe storms through sunrise:
Even if storms aren’t strong or severe, they may produce heavy rain and frequent lightning.
While the Flash Flood Watch will expire at 6am, the threat for flooding and heavy rain returns Saturday afternoon and evening. The threat for strong and severe storms will also be higher Saturday, especially for areas east of Cincinnati:
The most likely time for storms – including strong to severe storms – Saturday is 2pm to 9pm. Damaging straight-line wind is the main threat:
The key takeaways here are to be aware for flooding and strong storms through Saturday night. The risk for both of these is highest northwest of Cincinnati tonight and along and east/south of I-75 and I-71 Saturday afternoon and evening. Never drive through flooded roads!
