EF1 tornado in Boone County, Kentucky

The tornado first touched down near a home on Stevens Road in northern Boone County, northwest of Idlewild, causing minor roof damage to the home and damaging trees on the property. About a mile downstream, the tornado struck a barn, removing the roof and collapsing the walls. Numerous trees were also uprooted in the vicinity of the barn. Roofing material was lifted and deposited a considerable distance downstream, with roofing material lying along I-275 almost a half of a mile downstream of the barn. The tornado continued east along I-275 causing sporadic but minor tree damage. Another barn was damaged with partial roof removal on the south side of I-275. Some of this material was carried across I-275 and deposited about a half mile downstream on a nearby golf course. The tornado appears to have lifted in the vicinity of I-275, about a mile west of Exit 8.

There were some gaps in the damage path, indicating the tornado was not in complete and constant contact with the ground. The vast majority of the tree damage indicated wind speeds between 60 and 75 mph, though indications of wind speeds around 90 mph were present with the heavily damaged barn on the south side of I-275.

Thunderstorms developed during the afternoon and evening hours as a low pressure system moved through a warm and humid airmass that was in place across the Ohio Valley.
