A tornado touched down a little over 3 miles west southwest of Marquand, MO, near the intersection of Madison 310 and County Road 311. In this location, several large trees were snapped off, a tv tower antenna was bent, and a portion of the roof of an old barn was blown off. The damage width in this area was about 125 yards wide and rated EF1. The tornado tracked to the northeast, crossing Highway M. As the tornado crossed Highway DD, just south of intersection with Madison 314, hundreds of trees were either snapped off or uprooted. Also, tin from a carport was thrown several hundred yards from where it originated. Damage path width in this location was about 250 yards wide and rated EF1. The tornado continued to the east northeast, with sporadic tree damage, for about another 1.5 miles before lifting and dissipating. Overall the tornado was rated EF1 with a max wind speed of 110 mph.

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 Enhanced Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 20:00 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.
