A nearly stationary closed low located over southern Saskatchewan generates areas of rain over northeastern Montana, including portions of Blaine County. Partial clearing along the Rocky Mountain Front allows just enough heating to destabilize the atmosphere and form a band of showers with isolated thunderstorms along a line from near Cut Bank to Great Falls.
