An F0 tornado briefly touched down near the Horn Hill community. The first touch down was near the intersection of County Roads 85 and 97 and damaged the roof and some siding of a house. The weak tornado then moved east and blew down some trees on County Road 99. A couple of the trees fell onto a trailer and damaged it. The tornado then briefly touched down one last time near County Road 77 and blew more trees down before dissipating. No one was injured.

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.
