A shower moving across Madison, Franklin and Delaware Counties in central Ohio produced a persistent funnel cloud and a few brief tornado touchdowns. The shower moved across the western and northern portions of the Columbus metropolitan area.

A tornado touched down in a field just west of State Route 142 and south of Interstate 70 a few miles northeast of West Jefferson in eastern Madison County. Several trees were damaged and at least one was ripped out of the ground and tossed across State Route 142. The path length extended for about 200 yards. The tornado touched back down about 1.5 miles to the northeast in western Franklin County near a residence along Amity Road just north of Interstate 70. Additional tree damage occurred in this location. This tornado was rated EF-0 with maximum wind speeds of 75 mph.

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.

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 General Thunderstorms Risk. The outlook in force was issued at 16:02 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.

41 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.
