Thurs-Fri Snow

Sun-Mon Snow

Moderate to heavy snow will return to the Northern Rockies Thursday through Friday, particularly for higher elevations above 4000 feet. Moderate to heavy snow will create difficult winter travel over area mountain passes, particularly Marias, Lookout, and Lolo Passes. Snowy, slick travel will also impact MacDonald, Lost Trail, and to a lesser extent Homestake Pass as well. Valleys across the region - especially across Northwest Montana north of I-90 - will likely receive light to moderate snow accumulations.

Periodic light to moderate snow will bring continued impacts to portions of western Montana and central Idaho Sunday through Monday morning. Mountain passes, particularly Lolo Pass and Lost Trail Pass, will experience heavier snow amounts along with changeable visibilities. In the valleys, impacts will be less intense, but still noticeable: many locations may mix with rain for a time Sunday before turning back over to snow. As a result, roads could become briefly snow covered and quite slick, especially if road surfaces freeze up quickly.
