February 10, 2024 Severe Weather

Overview

A line of showers and thunderstorms developed in the early morning hours of February 10, 2024, ahead of a cold front in an environment that had very strong shear but little instability. The storms, mainly in southern Indiana and portions of north-central Kentucky, ended up morphing into a convective line that produced both wind damage and isolated tornadoes before weakening and pushing east of the region by sunrise. A total of two small, short-lived EF-1 tornadoes developed with the line.

Est. Peak Winds	90 mph
Path Length	1.0 mile

Summary: An EF-1 tornado impacted the community of Port Royal, Kentucky. The tornado touched down east of Gullion Branch Road and caused scattered tree damage. The tornado then moved into the town of Port Royal and did more significant damage near Port Royal Road. A pole barn was completely destroyed and its debris was carried more than a quarter-mile to the east-northeast. Several other structures had roof and siding damage. Several trees were snapped or sheared apart, with roof debris wrapping around some of the trees. Tree debris was in a convergent pattern, with most of it pointing toward the southeast to northeast directions. Nearby vehicles had mud splatter from the tornado as it tore through that portion of town. One vehicle was lifted, moved several feet away, and rotated 90 degrees. The tornado impacted trees further east before lifting in a field, as damage could no longer be observed to the east using a drone. More...
