An unseasonably warm and moist air mass was in place across the region during the morning hours of March 1st. Showers and thunderstorms developed across the Ohio Valley during the early morning hours as a strong low pressure system lifted northeast into the Great Lakes region. These storms produced heavy rain, large hail and several tornadoes. A squall line then moved through the region during the mid morning hours ahead of an approaching cold front. These storms resulted in damaging winds and additional heavy rain.

At a location on Sanders Road just west of US Route 62, a barn roof was significantly damaged with roofing material thrown to the east as much as a half mile away. A few trees were downed in this area.||Damage was most significant at a dairy farm on State Route 136, about 1.3 miles south of Millers Chapel Road. A large barn at this property experienced a significant amount of roof damage, including a total loss of the roof on the east side of the structure. Insulation, wood beams, and sheet metal from this roof were scattered across the property and well into a field across State Route 136. A roof was also removed from a dog kennel and a roof was partially removed from another barn at the property. Other outbuildings had minor damage as well and another house sustained minor roofing damage and several broken windows, along with some damage of siding. Trees were snapped or downed at this property, as well as along a tree line further to the west.||Tree damage occurred on Millers Chapel Road near the intersection with Poole Lane. A few other trees were snapped in the field just to the north of Poole Lane, but damage was not observed west of the end point of Poole Lane.

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.

The county was under a tornado watch, issued at 10:57 UTC and running to 13:52 UTC.

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 05:42 UTC.

38 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.
