WINTER WEATHER ADVISORY continues for the Bitterroot/Sapphire Mountains, Clearwater Mountains, Kootenai/Cabinet Region, West Glacier Region, Lower Clark Fork Region, Butte/Blackfoot Region, Potomac/Seeley Lake Region, Flathead/Mission Valleys, and the Missoula/Bitterroot Valleys until 8 am Monday. Snow accumulations of 2 to 6 inches will be possible in the valleys with up to 8 over mountain passes. Locally higher in the valleys from Missoula north to Kalispell.
WINTER WEATHER ADVISORY for Beaverhead, Madison, Jefferson, Broadwater, Meagher and Gallatin Counties until 5 pm Sunday. Snow accumulations of 1 to 2 inches in the lower valleys, 2 to 6 inches for mountain passes, and 8 to 12 inches in the higher elevations and West Yellowstone areas.
A storm system will develop over western Montana Sunday and continue into early Monday. All areas will receive snow, with the heaviest from Missoula north to Kalispell and south and southeast of Bozeman. Travel conditions will deteriorate through the day Sunday and Sunday night. We are fairly confident that areas north of I-90 will see all snow through the day Sunday, but locations south of I-90 may transitions back to a rain/snow mix during the afternoon, before changing to snow Sunday night.
A brief break from the unsettled weather is expected late Monday. The bulk of Tuesday will be dry, but our next weather maker could arrive as early as Tuesday night. Accumulating snow is possible Wednesday through early Thursday.
