During the early morning hours of May 7th, a cluster of strong and occasionally severe thunderstorms over central Illinois gradually grew upscale into a bowing line of storms as it moved southeast into central and southern Indiana toward dawn. Ahead of the developing quasi-linear convective system, a moderately unstable environment was present across southern Indiana, with MLCAPE ranging from around 500 J/kg in the east to around 1500 J/kg in the west. The line of thunderstorms generally produced sub-severe wind gusts across southern Indiana, as the strongest winds remained aloft thanks to a residual nocturnal stable layer. However, as storms approached the Ohio River, a few discrete cells moving from west to east were overtaken by the line which was moving from north-northwest to south-southeast. In the fifteen minutes or so after these cell mergers took place, five brief spin-up tornadoes occurred in Floyd County, producing pockets of structural and tree damage across the county. All of the tornadoes produced either EF0 or EF1 damage, with estimated wind speeds generally between 75 and 105 mph. Minor straight-line wind damage was also observed as this line of storms moved through. The severe threat ended by 10 a.m. as storms pushed southward into central Kentucky.

At 3424 Hamby Road, several trees were snapped and uprooted. Trees were facing from the east northeast to a southeasterly direction. Branches from the trees were scattered from the northeast to the southeast direction. An outbuilding had some siding and gutter damage. Of particular note was a large, healthy red oak tree that was uprooted with a significant root ball, which hit the far corner of the neighbor's house, doing structural damage to the roof and gutters.
The vast majority of the damage was to the trees, and just off the ground. The tornado topped a few trees at the edge of their property by the forested area, before lifting. Wind speeds of 90 mph were estimated, with a width of 100 yards, across this very short tornado track.

The tornado first touched down on the northwest portion of the Brookside subdivision (near the eastern portion of Georgetown Lake), with a couple larger branches of two older compromised trees twisted off. The Brookside subdivision is located just south of Indiana Route 64 and just east of Baylor Wissman Rd. There were over a dozen homes sustaining shingle, soffit, gutter, and fascia damage with many tarps on roofs. Shingles were thrown from an east northeasterly direction to a east southeasterly direction. There was little if any tree damage inside the subdivision, with one playground lifted and thrown into a fence. Drone photography showed the vast majority of the damage was to shingles and to soffits. The damage was estimated to be EF0 with 80 mph winds. The last damage point was in a wooded area just east of Zachary Trail before interstate 64. One tree was topped in that grove of trees.

The tornado first touched down on the Indiana University Southeast campus, on the west side of the Natural Science and Nursing building. There was roof and siding damage to the building. Trees between the parking lot and Grenadier Drive were
facing east, north, and to the northwest.
Power poles were snapped along Highway 111 (Grant Line Road). Apartments along Countryside Drive had shingle, gutter and downspout damage. However, one of the apartments had a large section of its roof removed with debris being thrown in all
directions. Two people in the apartment building were injured with head lacerations. Shingles were thrown several hundred yards. Trees were uprooted, snapped and twisted along Countryside Drive and Melvyn Drive. Trees were facing from the northwest to the southeasterly direction. Wind speeds in this area were 100 mph
with a width of 125 yards. One house on Melvyn Drive had no damage except for a piece of gutter that was thrown as a missile in a northerly direction through a window into their living room. Thankfully no one was injured at this location.
One outbuilding was thrown to the south, while another outbuilding was thrown to the north, three houses apart. Powerlines were snapped, and one large piece of roofing material from the apartment was impaled into the ground. There was numerous wooden and metal fence damage between Melvyn Drive and Preswick Square. A
very big, healthy oak tree was uprooted and was facing an east northeasterly direction. Wind damage in this area was consistent with an EF1 tornado, winds of 105 miles per hour, and a width of 100 yards.
The last damage was just on the other side of Klerner Lane, which was some low-end EF1 90 mph topped tree damage. In addition to a ground survey, drone photography was used, and there were several videos of a funnel on social media.

The first area of damage was at The Sporting Club at the Farm on Indiana State Road 111. Two large barns had significant roof damage and there was shingle and soffit damage to a large, well-built house. Of significance, a 110-pound storm cellar door was sucked out and thrown almost 100 yards to the east. There were 3 trees uprooted
and facing from north to an easterly direction.
The 600-pound sign for the sporting club was lifted up and moved to the north several feet. The tornado crossed Highway 111 and snapped and twisted over a dozen trees along the west side of the Ohio River. Because of the 110-pound bolted tornado shelter door being sucked out, the tornado rating increased from 95 to 100 mph. The
width was 100 yards wide.
The tornado continued near Five Mile Lane and River Road in Floyd County along the Ohio River where shingles were lost on a residence and a barn garage received significant roof damage where the metal panels were peeled off. The tornado then crossed the Ohio River into Kentucky in the Lake Dreamland area of West Louisville in western Jefferson County.
