Overview

Severe thunderstorms developed along a weak convergence zone from northeast Colorado into southwest Nebraska during the late afternoon on 13 August, 2019. A thunderstorm cluster moving south across western Nebraska merged with the developing thunderstorms and evolved into a forward propagating mesoscale convective system that produced widespread high winds from northwest into central Kansas. The greatest damage occurred in Ellis County, where winds were estimated at near 90 mph. Here is a damage summary KMZ file that is viewable in Google Earth.
