Severe storms overnight expected to stay largely south of I-70 in southern Ohio, NWS says

After a stormy Tuesday night brought tornado warnings, heavy rain and a flood advisory to central Ohio, storms with heavy rain are still possible in the region late Wednesday night into early Thursday morning, according to the National Weather Service in Wilmington.

However, the Columbus area no longer has a hazardous weather outlook — a statement released by NWS describing severe storm risks—and the chances of severe weather are "marginal", according to an NWS map published on X (formerly known as Twitter).

The best chances for showers and thunderstorms Wednesday night into early Thursday are south of Interstate 70 and in southern Ohio.

At 11 p.m. Wednesday, some thunderstorms were moving west to east largely along and south of Interstate 70 toward Circleville. Some storms with heavy rain may push north of that in the early morning Thursday.

The NWS has issued a flood watch through Thursday morning for Adams, Pike, Ross, and Scioto counties in south central Ohio and for Athens, Gallia, Jackson, Lawrence, Meig and Vinton counties in southeast Ohio. Heavy rain expected on already saturated soil are expected to flood river, creeks, streams, and other low lying and flood prone areas.

Tuesday's storms swept through around 10:30 p.m., prompting a series of tornado warnings in Franklin and other surrounding counties to the northwest, north and east. However, there were no reported tornadoes in central Ohio.

NWS Wilmington assessment teams went out Wedneday to confirm reported tornadoes, and it appears there may have been four in its Ohio coverage area: damage from a suspected EF1 tornado in the Hickory Woods Campground in Franklin County, Indiana, that continued into Butler County, Ohio, going south of Oxford (home of Miami University) near McGonigle; a survey in Mercer and Auglaize counties that found damage along Guadalupe-Southland road that was "tornadic in nature" with damage beginning in Mercer and extending into Auglaize, west of New Knoxville; a third in Mercer County, west of Coldwater; and a fourth in Darke County in and near Greenville.

NWS Pittsburgh reports an EF2 tornado started in Jefferson County, hitting Irondale, and traveled 15 miles through Hancock County, W.Va., into Beaver County, Pa. with a maximum sustained wind around 130 mph and a maximum width of 200 yards. One injury was reported. Assessment teams from the NWS Pittsburgh office plan on Thursday to survey reported tornado damage in Coshocton and Muskingum counties in Ohio.
