A line of severe storms advanced from Illinois and intensified further as it interacted with strong instability and shear. The line took on a line echo wave pattern (LEWP), resulting in an abundance of wind damage reports, including a focused micro-burst in Williams County. A brief tornado also developed in Van Wert County, resulting in some damage.

Emergency management officials surveyed an area of damage south of Van Wert and determined a circulation touched down in a wheat field a quarter mile west of Dustman Drive and US 127. The circulation continued along Dustman Road, with most of the damage being to trees. A few limbs fell onto homes, causing minor damage. In addition, some shingle damage occurred. The roof of a barn was torn off near US 127 as well. Winds are estimated to be between 80 and 85 mph with a maximum width of the tornado of around 50 yards.

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 Moderate Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:00 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.

11 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.
