Hail:

Large hail was observed with the supercells. Hailstones were larger than golf balls in some of the storms, beginning with the Owensboro, KY storm around 1 P.M. The storm that produced the EF-1 tornado near Bancroft in Muhlenberg County, KY also produced baseball-size hail about 5:30 P.M. The storm that produced the EF-0 tornado near Cerulean, KY also dropped hailstones about the size of baseballs. Finally, there were reports of quarter-size hailstones in Hopkinsville around 8:40 P.M., mainly on the northeast side of town.

Damaging straight-line winds were observed with a few storms. However, tornadoes and large hail were the main culprits behind most of the damage.

Environment

The environment became supportive of supercells during the afternoon. With daytime heating, surface-based cape increased to nearly 3000 j/kg in the southwest corner of Kentucky by 21z. Deep-layer wind shear was sufficient for the initiation of supercells.
