A deep occluded closed low across the Upper Midwest brought a cold front and wind shift along the Ohio River during the early evening hours on June 22nd. Scattered storms developed to the west of Louisville during the late afternoon and intensified as they moved east into Jefferson County, Kentucky. Although instability was marginal, a jet streak aloft combined with directional wind shear closer the the surface allowed several low topped supercells to develop just to the west of Louisville. The first storm generated a tornado that damaged several horse barns at Churchill Downs and destroyed a large industrial building just southeast of the University of Louisville's football stadium.  A second rotating supercell tracked just to the south of the first storm, spawning three brief tornadoes along a west to east path in the eastern part of the Louisville Metro area.

This tornado touched down just southwest of an area of horse barns on the south side of Churchill Downs. Five barns, which also contained apartments for many workers, had major sections of their roofs removed, with minor damage to several others. In the buildings most heavily damaged, parts of supporting walls made from cinder blocks collapsed.  Christ Church, located on the Churchill Downs property, also had roof and siding damage. After snapping trees and downing power lines for several blocks to the east of Churchill, the tornado crossed a large stadium parking lot, strengthening to low-end EF-2 intensity near the intersection of Floyd Street and Central Avenue. At this location, just 300 yards southeast of the University of Louisville's football stadium, a large industrial building was heavily damaged, with a collapsed 2-story cinder block wall and a 150-foot section of roof removed from the warehouse.  A 30' x 80' section of roof over an adjacent office building was also torn off.   The tornado downed several more trees and did minor roof damage to a Super 8 Motel and other office buildings before lifting north of the intersection of Crittenden Drive and Central Avenue near an entrance ramp onto Interstate 65.
Despite the most heavily damaged Churchill Downs buildings being occupied by numerous racing horses and at least three workers at the time of the tornado, no injuries were sustained by either the animals or their handlers.  One man was in an upstairs room when the roof above him was ripped off, while two others were in in a ground-floor apartment where cinder blocks fell from an exterior wall.

This tornado was the first of three separate touchdowns associated with a single supercell that tracked across the southern portion of Jefferson County.  Initially, this tornado touched down at EF-0 strength near the intersection of Nachand Lane and Nachand Spring Lane where minor shingle damage and snapped trees were surveyed. After moving into the Hurstbourne Woods subdivision, the twister damaged a locked pool gate and blew it 35 yards downwind. This subdivision sustained EF-1 damage with gutters, soffits, and siding from various structures deposited in trees. At 9407 Willowwood Way, roof damage was noted, along with many uprooted hardwood and softwood trees. After making a brief 25 degree northward turn near the end of its life, the tornado brought minor roof damage before lifting near the intersection of Lisa Lane and Calais Drive.
