A tornado touched down west-southwest of Addieville damaging several homes on the southern part of town. Several roofs were partially torn off or damaged by falling trees. It crossed Interstate 64 knocking down several trees and shearing highway signs off. As the vortex crossed Highway 127, an 80-foot radio tower was destroyed and two large utility buildings were heavily damaged. As it continued to move east-northeast it damaged homes and buildings on two area farms reaching its maximum width at this point. Before lifting south of Hoyleton, the tornado damaged more farm buildings, a grain silo, and numerous large trees.

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.

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 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 St Louis radar (KLSX), 107 km away, was scanning. The volume nearest the touchdown began at 18:16 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.
