The wider storm

An upper level trough moved from southwest Oregon on the morning of August 25th to southern British Columbia by the morning of the 26th. This system initiated strong thunderstorms on the evening of the 25th and also during the early morning hours on the 26th. These storms produced gusty winds that caused trees to topple over causing power outages and vehicle damage across portions of northwest Montana.

Began near Kalispell (48.1897, -114.3183).
