6 damage points were recorded along this path by NWS ILN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 75 mph.

• Metal shed which was lofted over a tree line. Debris found 200 feet away to the northeast.
• Cross-directional to the path of the circulation viewed by TCMH radar.

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

A brief tornado occurred along Watkins Road SW, between Interstate 70 and US Route 40. Damage was very localized and consisted mostly of snapped or uprooted softwood trees. Despite the lack of numerous damage indicators, several trees were uprooted in a cross-directional orientation, nearly perpendicular to the direction of the tornado's movement northeast. These trees, in combination with low elevation radar data from the TCMH Terminal Doppler Radar, provided enough evidence to support the determination of a tornado. Any damage further to the southwest or northeast of the|damage on Watkins Road SW was either minimal or inconsistent to extend the track for this tornado.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a tornado watch, issued at 18:29 UTC and running to 23:00 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 19:40 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), 116 km away, was scanning. The volume nearest the touchdown began at 21:42 UTC.

15 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.
