What happened

The episode as NWS PAH wrote it up.

A severe thunderstorm developed over eastern Union County, damaging a barn northeast of Morganfield on Highway 359. The roof and walls were blown off the barn, and a tool shed was damaged. In Morganfield, a vehicle was damaged by hail. The severe thunderstorm then moved east across Henderson County, passing just south of Henderson. Trees and signs were blown down in Corydon, and a tin roof was blown off a garage. At least one tree landed on a house. The storm continued east across the northwest corner of Daviess County, producing quarter-size hail at Stanley. Wind-blown hail dented vehicles and the siding of houses. The storm passed just north of Owensboro into Indiana, then clipped the northeast corner of Daviess County as it moved east.
