A F0 tornado (winds 40 to 73 mph on the Fujita Scale) moved from west to east, nearly parallel to State Rd. 2 near the Blackman community. The only major structural damage was to a large chicken facility, west of Blackman. A pump house to one home was overturned. Numerous trees in the tornados path were blown down as well as power lines. Most of the time the circulation was aloft as a funnel cloud, but briefly touched down as a tornado about 7 times during its life span.

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.

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.

5 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.
