The best chance for severe weather is from 9 p.m. to 3 a.m. around and north of Interstate 70, according to the NWS.
The Miami Valley has a slight risk, or level 2, chance for severe weather.
A slight risk means scattered severe storms are possible with short-lived and/or isolated, intense storms, according to the NWS.
A lull is expected in storm activity by early Friday. Showers could continue late into the morning though.
Another round of storms will develop and head northeast Friday afternoon into Friday night.
The second round is expected to be more severe with most of the Miami Valley at an enhanced risk, or level 3, for strong storms.
Under an enhanced risk, numerous severe storms are possible, as well as more persistent and/or widespread storms. There’s also a chance for a few intense storms.
The best timing for strong storms is from 5 p.m. to 1 a.m., according to the NWS.
Damaging winds, hail and tornadoes are possible, along with heavy rain.
