Scattered showers and thunderstorms developed ahead of a low pressure system moving through the Ohio Valley.

The tornado first touched down on the west side of South Tipp-Cowlesville Road where a detached garage had part of its roof lifted and removed, with concentrated tree damage throughout the rest of the property. Some roofing material was carried across South Tipp-Cowlesville Road into adjacent fields, approximately 200 yards downstream. On the east side of South Tipp-Cowlesville Road, a grove of trees sustained some damage with large branches snapped and broken off. The tornado then continued northeast toward Tipp Canal Road, where it likely lifted on the west side of the road in an open field. Here, trees on the west side of the road in the distance clearly had been snapped and broken off near the top.||The damage was consistent with wind speeds of around 70 mph.

23 minutes of warning. NWS ILN issued a tornado warning for this county at 23:00 UTC, 23 minutes before the tornado touched down, in force until 23:30 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 Marginal Risk. The outlook in force was issued at 20:00 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 Cincinnati radar (KILN), 65 km away, was scanning. The volume nearest the touchdown began at 23:24 UTC.

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.
