Light Snow Mountain Pass Snow This Weekend

Headed over the passes this week? 🏔️ Winter driving conditions are making a comeback. Expect snow levels to steadily drop down to 4,000 ft by Friday across Western Montana and North Central Idaho. Passes like Homestake, Lolo, and Lookout may see slick spots, especially during the overnight and early morning hours. Roughly 2-3 inches of snow will be possible Weds and Thurs mornings for Lolo and Lookout passes, specifically. Down in the valleys? Grab the rain gear and watch out for morning fog. 🌧️ We might even see some wet flakes mix in by the end of the week, especially in northwest Montana.

Minor travel impacts are expected late Saturday night through Sunday as another system brings light snow to mountain passes across Idaho County, Lemhi County, and Southwest Montana. Snow levels may drop as low as 5,000 feet, producing 2 to 5 inches of slushy accumulation on key routes including Lost Trail, Homestake, MacDonald, and Bannock passes. Wintry conditions may extend into high-elevation valleys by Sunday night. Motorists should prepare for slick surfaces, particularly during the overnight and early morning hours.
