An upper level short wave passing to the south of central Kentucky caused isolated storms in the predawn hours of June 24th. Rounds of storms developed along a nearly stationary surface boundary from late morning into the afternoon on June 25th. Some minor flooding occurred with repeated rainfall, and isolated cells produced severe weather across central Kentucky, including two small tornadoes.

This brief tornado did most of its |damage at treetop level, snapping|the trunks of or uprooting at least |two dozen large, mature oaks and cedars, |and causing limb damage to many others. |In one case, it snapped the 2-foot |diameter trunk of a large cedar less than |5 feet above the ground, but lofted the |tree over nearby utility lines - which |remained intact - and deposited the tree |200 feet to the east. ||The tornado did occasionally reach closer |to the ground, causing significant damage |to two structures. The first was a large |brick ranch home, which had most of the |north half of its roof torn off, and |insulation spread eastward in a narrow |path. One piece of roofing lumber was |found 500 feet ENE of the home. A second |building, a large 2-story brick industrial |building 1/2 mile east - had about 20 |percent of its metal roof peeled off. |Immediately after hitting this building |and downing trees in a nearby cemetery, |it crossed U.S. Hwy 62 and did additional |tree damage for another several hundred |feet as it moved through a wooded area. |The National Weather Service thanks Ohio |County Emergency Management for their |assistance in this survey, including |drone surveillance that helped |identify the path of this storm.

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 Marginal Risk. The outlook in force was issued at 12:34 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 Ft Campbell radar (KHPX), 79 km away, was scanning. The volume nearest the touchdown began at 15:50 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.
