A Tornado Watch was issued for most of the Miami Valley and will remain in effect until 5 am Thursday, putting the region under an overnight severe-weather threat as storms move through. The same system had already been producing warnings in Illinois and Indiana before it reached Ohio.
The setup gives the area the potential for a few tornadoes, and a strong tornado could not be ruled out. Storms were expected to exit the area around 2 am or a little after, which means the worst of the weather could ease before the watch expires, but the overnight risk does not end on that clock alone.
That is why people were told to have a way to get warnings tonight. NOAA weather radio was recommended as a reliable option, along with Wireless Enabled Alerts sent to a phone. Outdoor tornado sirens were not advised as the only source, because they can be easy to miss while sleeping or staying inside.
The watch covers most of the Miami Valley, but the specific counties were not identified in the available information. What is clear is that the severe threat is tied to the same storm complex that has been moving through Illinois and Indiana, and the concern now is whether the storms weaken and clear out before any additional warnings are needed overnight.
