A tornado touched down just southwest of Murrayville then moved northeast through town. It lifted and dissipated one mile northeast of town. In town, a large tree was blown over onto a home causing major damage to it and a car parked nearby. None of the home's occupants were injured. A garage was destroyed and the two vehicles parked in it were damaged. Also, a lumber yard was destroyed. On the northeast side of town a grain bin was destroyed and a church lost seven stained glass windows. Also, it sustained minor roof damage. Throughout town numerous trees, tree limbs, and power lines were blown down.

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 01:09 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.

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.
