EF0 tornado in Harrison County, Kentucky

A National Weather Service damage survey concluded that a brief EF-0 touched down early on the morning of Thursday June 18th, 2026. The brief spin-up tornado was embedded within a larger swath of sporadic straight-line wind damage, and touched down about 3 miles due west of Cynthiana between Mill Creek and Mill Creek Meadows Drive. Here, some tree damage as well as roof damage to a metal barn were sustained. Winds were estimated to be 80 mph with this damage. The tornado then traveled east of Mill Creek Meadows Drive toward Ammerman Pike doing more tree damage and scattering some roofing material from the upstream barn. At Ammerman Pike and

Highway 356, another metal barn sustained roof damage and had side panels blown out, along with some roof and fascia damage to a home. A large softwood tree was also uprooted here. Peak winds at this location were rated at 85 mph as the tornado made a hard northward turn and dissipated north of the Highway 356 and Ammerman Pike intersection. The tornado was on the ground for 1 minute or less and traveled less than three quarters of a mile. Peak width was estimated at 80 yards wide.

A Mesoscale Convective System moved across the Ohio Valley on the night of June 17th, 2026 and the morning of June 18th, 2026. Supercells congealed into a line of storms as it moved south into southern Indiana and northern Kentucky. These storms brought severe winds and a few tornadoes to the area. Additionally, long residence time of heavy rainfall lead to flash flooding that lasted through most of the day on June 18th, 2026.
