The southern three quarters of Indiana and most of Ohio have a slight risk of severe weather between 9 a.m. EDT today and 8 a.m. EDT tomorrow, according to an updated “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 8:47 a.m. EDT.

In IMO SKYWARN quadrant two, the slight risk area includes extreme southern Huntington, Wells and Adams Counties, Blackford County, Jay County, southeastern Van Wert County, southeastern Putnam County and Allen County, Ohio.

The primary threats are damaging straight-line thunderstorm winds of 58 mph or stronger and hail of one inch in diameter or larger, but meteorologists cannot rule out an isolated tornado, as well.

Meteorologists expect any severe thunderstorms to develop this afternoon. SKYWARN storm spotter activation is possible this afternoon, especially south of U.S. 24, according to the “Hazardous Weather Outlook” that the northern Indiana NWS office issued at 5:32 a.m.

The SPC will next update its outlook for today by 12:30 p.m. EDT.
