Affected:Northwestern Kentucky

This long-tracked, large F3 tornado touched down just west of Madisonville and immediately reached its peak intensity as it moved east-northeast into downtown. Multiple buildings and homes were extensively damaged, including a three-story brick building that lost its top two floors and two two-story brick buildings that had extensive damage. Trees and power lines were downed, an airplane was destroyed at the Madisonville Municipal Airport in nearby Anton, and cars were damaged by flying debris. All three injuries from this tornado occurred near or in town and losses totaled $2.5 million alone. From Madisonville, the tornado weakened and turned eastward, causing lesser, but still considerable damage as it hit Northern Millport as well as the towns of Bremen Station and Bremen. From there, it began to skip as it hit the town of Moorman, unroofing the Moorman High School gym and destroying a small home. Damage was also observed in Centertown, Beaver Dam, Mt. Pleasant, Arnold, Dogwalk, and Neafus before the tornado finally dissipating in Peth.

The tornado was on the ground for an hour and five minutes, tracked 58miles, and was 880yd (one source says 1320yd) wide. Three people were injured, and losses totaled $15 million. Despite the heavy damage, tornado researcher Thomas P. Grazulis gave the tornado an F2 rating. It is also possible that the tornado started in McLean County while never crossing into Grayson County.

Non-tornadic impacts

Numerous reports of large hail and wind damage were confirmed throughout the event. The biggest hailstone was recorded as being 3inches in diameter and was recorded twice in both Texas and Oklahoma as well as once in Kansas.[101] On May 6, the strongest winds were recorded in Tupelo, Mississippi, where 105mph gusts destroyed a plane and damaged several others at an airport.[102] On May 5, severe thunderstorm winds in Nebraska City, Nebraska destroyed an airplane hangar and tossed the plane inside into the trees nearby. In addition to the numerous tornadoes that occurred, one waterspout was confirmed to have taken place near Key West, Florida on May 9. Heavy snow of up to 8inches fell west of the Continental Divide in Montana with Missoula setting a record for the most snow seen in a 24-hour period with 6.5inches.
