Mid next week (Oct 27-29), Western Montana and North Central Idaho will see a mix of mountain snow and valley rain. Snow levels are expected to drop to between 4,500 and 5,500 feet, bringing slick travel conditions to area passes. Impacts are most likely during the overnight and early morning hours across Lookout, Lolo, Lost Trail, Marias, MacDonald, and Homestake Passes. In the valleys, expect rain, localized morning fog limiting visibility, and near-normal temperatures in the mid 40s to mid 50s.
