A tornado was on the ground for nearly 13 miles across Republic County while winds of up to 80 mph and baseball size hail were also reported across the area during the evening hours of April 24th.

Survey revealed that the initial tornado touchdown occurred around 650pm CDT just north of Belleville. The tornado then moved northeast and produced sporadic damage in rural areas of Republic County. It did hit the small town of Munden where several homes were damaged and a mobile home was destroyed. Another farmstead was also damaged northeast of Munden. The end of the tornado occurred south of Narka where some light tree damage was documented.

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.

The county was under a tornado watch, issued at 20:06 UTC and running to 03:51 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:45 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.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Grand Island radar (KUEX), 91 km away, was scanning. The volume nearest the touchdown began at 23:48 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.
