Northwestern Ohio and a small part of northeastern Indiana have a slight risk of severe weather between 8 a.m. EDT tomorrow, Friday, Sep. 20 and 8 a.m. EDT Saturday, according to the Day 2 Convective Outlook that the National Weather Service (NWS) Storm Prediction Center issued at 2 a.m. today. As you can see in the map above, the slight risk area includes the eastern half of Allen County, Indiana, most of Wells County and all of Adams, Blackford and Jay Counties. It also includes all Ohio Counties served by the northern Indiana NWS office (i.e. all Ohio Counties of IMO SKYWARN quadrants one and two).

According to the convective outlook, forecasters expect atmospheric conditions tomorrow to be far from what’s normally needed for widespread severe weather. There a chance, however, that some marginally severe storms could develop tomorrow afternoon and/or tomorrow evening. If they do, the main risk is from isolated damaging thunderstorm winds and possibly some hail.

We’ll have a much better look at the situation tomorrow morning, after the SPC issues its Day 1 Convective Outlook for tomorrow.
