Several power line poles (both from the local electric cooperative and the Department of Energy, which were replaced in recent years) were snapped at their bases in this area. A nearby home weather station recorded a 79 mph thunderstorm wind gust.

The wider storm

A near stationary low pressure surface trough, warm moist air from the southeast and a strong cold front from the west all combined to allowed many severe thunderstorms to develop and strengthen through the afternoon and evening hours. Later that evening and night, larger-scale post-frontal non-thunderstorm high winds brought additional damage.

Began near Cow Creek Dot (47.5900, -105.5300).
