Thunderstorms developed during the evening hours along a warm front lifting slowly north across the region. Many of the thunderstorms produced tornadoes, including a few strong to violent tornadoes.

The tornado is believed to have initially touched down in an open field behind a residence on Township Highway 95, Gunn Road, and began moving southeast. Two residences on TH 95 were impacted on the west side of the road. Numerous trees were snapped or uprooted with a grill thrown more than 50 feet. On the east side of the road, large limbs were downed and portions of a barn roof and several barn doors were removed. Tree limbs from the residence on the west side of the road were found to have been thrown well downstream, and the barn material from the residence on the east side was found wrapped in tree stands more than a half mile to the southeast, on the east side of TH 115. More large trees were found to have been snapped and thrown in tree stands between TH 95 and TH 115.||The tornado continued southeast and began to lift as it crossed TH 119, Silver Creek Road. On the east side of TH 119, more limbs were found to be thrown, albeit these limbs were considerably smaller than larger branches found along the first mile of the path. The tornado is believed to have lifted in an open field west of US Highway 68.||Damage along the path was consistent with wind speeds from 65 to 75 mph, or EF0.

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 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:18 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), 127 km away, was scanning. The volume nearest the touchdown began at 03:26 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.
