Overview

Severe storms pummeled central portions of eastern Kentucky during the evening hours of May 26, 2019. These thunderstorms developed along a surface boundary, in tandem with a mesoscale convective vortex.

These features helped to organize storms into a line, which swept across eastern Kentucky and produced several reports of damage. Numerous trees were blown down from Rockcastle to Martin and Pike Counties. This subsequently led to thousands of power outages across eastern Kentucky.
