Damp and muggy early-autumn conditions with several docile rain showers, also included a small shower that produced a very brief landspout tornado about 5 miles west-northwest of Muncie. The cell apparently developed along a weak boundary that extended to the west from where the landspout tornado occurred.

The landspout occurred at the northern end of the small Cammack neighborhood within the north side of the Yorktown area, specifically immediately east of the northern end of Cammack Street. Here the narrow vortex tracked to the east-northeast, quasi-parallel, yet across the longitudinal axis of a 200 by 80 foot pole barn. The landspout both began and ended at approximately 1839 EST.||The barn sustained damage to portions of its west side where the wall collapsed inwards; although little to no damage occurred to the frame/structure of the building. |Primarily sheet metal was blown inward into the building and outward back to the west, while remaining parts of the metal building were not damaged. No other damage was found to adjacent properties.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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 General Thunderstorms Risk. The outlook in force was issued at 19:46 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 Indianapolis radar (KIND), 87 km away, was scanning. The volume nearest the touchdown began at 23:35 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.
