As a cold front moved southeast across the upper Ohio Valley, scattered severe thunderstorms developed across eastern Ohio, western Pennsylvania, and northern West Virginia. A supercell thunderstorm produced an EF1 tornado in Carroll and Jefferson counties in Ohio, with numerous reports of wind damage and hail up to golf ball size elsewhere. Flooding of streams and creeks also occurred over eastern Ohio and the northern panhandle of West Virginia.

An EF1 tornado was confirmed by a NWS storm survey with a maximum wind speed of 90 MPH. A supercell thunderstorm produced a tornado that touched down 10.5 miles east of Carrollton in eastern Carroll county for almost a mile and one half and exited Carroll county just north of the intersection of of Township Highway 317 and SR 164 around 1701EST. The tornado continued into northwest Jefferson county before dissipating around 1705EST 4 miles northeast of Bergholz with a total path length of approximately 4 miles. The maximum width was about 300 yds. The tornado was EF1 in both counties with trees toppled or snapped. Structural damage included a porch roof, shingles off roofs, broken windows and siding torn off homes. A chimney was knocked down and numerous outbuildings suffered roof or wall damage. A large tree also fell on a mobile home.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a severe thunderstorm watch, issued at 17:48 UTC and running to 00:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:46 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Pittsburgh radar (KPBZ), 54 km away, was scanning. The volume nearest the touchdown began at 21:58 UTC.

7 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
