Thunderstorm Wind — Mccone, Montana

2021-06-10 · near Cow Creek Dot, Mccone, Montana

Event narrative

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.

Wider weather episode

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.
