A strong upper level system brought abundant moisture into the region, which combined with a cold front to bring heavy rain and flooding along with strong thunderstorms.

The tornado first touched down at a residence just northwest of the intersection of Greenville-Nashville Road and Hillgrove-Southern Road. A wood and siding covering over the south-facing porch was lifted over the house and strewn for approximately 150 yards to the northeast. Roof damage also occurred, most likely resulting from the debris coming into contact with the roof. No debris spatter was observed on the opposite side of the house, but the debris remained confined to a narrow path approximately 75 yards wide. The uplift and convergence of the wood and siding porch debris was deemed consistent with damage caused by a 70 mph EF0 tornado. ||The tornado then appeared to lift, before causing very minor tree damage along Hillgrove-Southern Road between Greenville-Nashville Road and State Route 502. This damage was likely caused by low-end EF0 winds of no more than 65 mph.||The tornado then lifted again, with evidence of an additional touchdown just east of the State Route 502 and Hillgrove-Southern Road intersection. Two locust trees approximately 18 inches in diameter were snapped, and one pine tree approximately 30 feet tall was uprooted. Minor roof damage also occurred on the nearby house and outbuildings. The locust trees were not completely solid, with some rot in the center of both trees. This damage was deemed consistent with 65-70 mph winds of an EF0 tornado.

5 minutes of warning. NWS ILN issued a tornado warning for this county at 02:02 UTC, 5 minutes before the tornado touched down, in force until 02:15 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 General Thunderstorms Risk. The outlook in force was issued at 00:56 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), 111 km away, was scanning. The volume nearest the touchdown began at 02:09 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.
