Strong to severe thunderstorms developed along an advancing warm front. A couple of the thunderstorms produced tornadoes.

The tornado first touched down near Edwin Shoemaker Road and Tener Road in far northeastern Adams County. This damage was limited in scope and consisted of a few trees downed. Minor tree damage was also observed on another section of Tener Road near the Adams-Pike county line. From here, the tornado moved northeast across an inaccessible area.||The most significant damage from this tornado occurred along Humphrey Road and Hackleshin Road in an area known as Humphrey Hollow in Pike County. Tree damage in this area was extensive, especially on the steep hillsides surrounding the hollow. The tornado lifted near Sunfish Creek and State Route 124 east of Latham.

The tornado first touched down near Edwin Shoemaker Road and Tener Road in far northeastern Adams County and moved northeast into Pike County.||The most significant damage from this tornado occurred along Humphrey Road and Hackleshin Road in an area known as Humphrey Hollow. Tree damage in this area was extensive, especially on the steep hillsides surrounding the hollow. On one northwest-facing hillside around a bend on Humphrey Road, nearly every tree was uprooted down the hill. A few snapped trees were also noted in this area. There was strong evidence that the most significant damage occurred on the slopes facing downward along the direction of the wind; including generally east-facing slopes on the south side of the tornadic circulation, and west-facing slopes on the north side of the circulation. While structural damage in this area was mainly limited to impact damage from trees, some minor siding and roofing damage was noted at a few properties.||After leaving Humphrey Hollow, the tornado continued northeast across another inaccessible area, before causing similar tree damage along Grassy Fork Road and Fields Hollow Road in Fields Hollow.||Minor tree damage was observed along Sunfish Creek and State Route 124 east of Latham, with no evidence of damage reaching very far to the north of State Route 124.

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 19:43 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 Cincinnati radar (KILN), 60 km away, was scanning. The volume nearest the touchdown began at 21:55 UTC.

10 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.
