An isolated rain shower produced a landspout over northwest Kentucky near Sebree. The rain shower was associated with a weak stationary front that extended eastward from the central Plains across the Lower Ohio Valley to the central Appalachians.

A slow-moving funnel cloud was observed for about five minutes over open country. A trained spotter reported the funnel touched down as a tornado for a few minutes and stirred up some debris. No damage site was located by the spotter or reported by other sources. This tornado was associated with an isolated light rain shower. This type of tornado is commonly called a landspout. Landspouts occur when extremely buoyant air is lifted and rotates near the base of a rain shower of thunderstorm. Most landspouts do little damage.

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 20:12 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 Evansville,IN radar (KVWX), 83 km away, was scanning. The volume nearest the touchdown began at 20:26 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.
