EF1 tornado in Calloway County, Kentucky

Peak winds were estimated near 95 mph. Hundreds of trees were uprooted or snapped. Windows were blown out of a house, and shingles were damaged. Shutters were ripped off the house. Three barns were destroyed. Two garages were levelled. A section of roof was peeled off another garage. The porch roof of a business in Hazel was destroyed. A large tree fell across a truck.

A potent upper-level trough moved east into eastern Kansas and Oklahoma, before assuming a negative tilt and accelerating east-northeast across the Mid-Mississippi and Lower Ohio Valleys. The associated surface low tracked northeast from Kansas across northern Missouri to southern Wisconsin. Ahead of the low and trough, a south-southwesterly low-level jet in excess of 50 knots expanded east across the Mid-Mississippi Valley. An expansive quasi-linear convective system formed along the lead cold front trailing southward from the surface low. Despite rather meager instability, very strong low and mid-level wind fields resulted in organized storm structures with pockets of damaging wind, isolated large hail, and a couple of tornadoes.
