The tornado touched down in an grove of trees, uprooting and breaking off numerous large trees. As the tornado moved southeastwards, it encountered a farmstead where it ripped off the roof of the home, destroyed a machine shed and garage, and broke power poles. Before lifting, the tornado moved through a field and overturned the end of a center pivot irrigation system.

The tornado touched down in a cornfield and overturned a center pivot irrigation system as it moved west southwestwards. Nearby, large tree limbs were broken off and a roof was taken off an open detached garage at a farmstead. Then the tornado encountered a second farmstead where it lifted an unanchored manufactured home and smashed it on top of a camper trailer and a detached garage, destroying them. It also lifted a semi-trailer and dropped it onto a John Deere tractor and a pickup sitting next to it. Debris from the house and garage was carried into the cornfield to the west. The tornado continued moving west southwestwards breaking tree limbs before lifting. A husband, wife, and their daughter were inside the home when it was destroyed. The woman was hospitalized with a broken neck and the girl required numerous stitches from lacerations on her leg. The man only received minor cuts and bruises.

The tornado touched down in open rangeland and then moved south breaking off and uprooting numerous large trees as it encountered a farmstead. One large tree fell on the roof of a home. As the tornado moved south across the road, it hit another farmstead. Again, it broke off and uprooted numerous large trees and broke many power poles. The barn and steel fencing was lifted and tossed 50 yards northwestwards into a tree belt behind the house. The roof of the home was taken off. A detached garage was demolished. Before lifting, the tornado moved through a corral south of the home where it severely injured or killed several horses. After the storm, two colts and a mare were found up in a tree.

19 minutes of warning. NWS LBF issued a tornado warning for this county at 00:11 UTC, 19 minutes before the tornado touched down, in force until 00:45 UTC.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:37 UTC.

13 more were confirmed in the United States that day.

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.
