A very unsettled and cool week is expected across western Montana. A surface cold front will usher cooler air into the region tonight and Tuesday. A large, upper level trough of low pressure will park itself over the northern Rockies this week. One storm within the trough will bring a good chance of rain through Thursday. Rainfall of a quarter of an inch up to an inch is possible across the region. A stronger storm system within the trough will move into the area this weekend, bringing widespread rain and snow to southwest Montana, especially around Bozeman.

Gusty winds will accompany the cold front tonight and Tuesday. Highs will drop to the 50s through Tuesday.
