A line of thunderstorms which developed ahead of a pre-frontal trough of low pressure, produced isolated tornadoes.

The tornado touched down in a field just northwest of the|intersection of Neff Road and Hahn Road, continuing northeast across|the 5200 block of Gettysburg-Pitsburg Road, where it left a home|untouched but knocked down a rotted tree just behind it. A barn|behind the home sustained significant damage, losing a quarter of|its roof and the entire overhang attached to the back of the barn.|The sliding front door of the barn was also flipped up over the|roof. A small tractor trailer parked behind the barn was flipped|onto its side and was damaged by flying debris. Debris from the barn|was found strewn about 200 yards east into a soybean field behind|the farm. A few large branches were found snapped off a tree behind|the barn.||Drone footage shared by the Darke County Sheriff showed a continuous|tornado path through soybean and corn fields stretching a few|miles northeast of the initial touchdown location. As the tornado|tracked northeast from the damaged farm, it passed just about 300|feet north of a residence on Yount Road. Downstream crop damage|revealed the tornado crossed Byreley Road, Red River-West Grove|Road, and Grise Road. A small metal phone booth with a concrete slab|foundation was knocked over on Grise Road just west of State Route|721. The tornado path ended in a soybean field just east of the|Darke/Miami county line after crossing State Route 721.

0 minutes of warning. NWS ILN issued a tornado warning for this county at 22:15 UTC, 0 minutes before the tornado touched down, in force until 22:23 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 Marginal Risk. The outlook in force was issued at 19:59 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.

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.
