A tornado touched down in Abbotsford (Clark County), causing considerable damage. A large feed mill was demolished, with debris damaging 15 cars at a nearby car dealership. An electric generator from the feed mill was thrown about two blocks, damaging the front of a building, before coming to rest on a minivan, demolishing it. Utility poles were sheared off and tossed, as well as a railroad crossing guard. One power pole was tossed through a car window, while yet another car was picked up and tossed onto another. In addition to the tornado, straight-line winds estimated at 60 to 65 mph blew down numerous trees and power lines.

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.

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. The outlook in force was issued at 00:41 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 La Crosse radar (KARX), 143 km away, was scanning. The volume nearest the touchdown began at 03:16 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.
