Rain, mountain snow to impact travel
We are tracking a storm system that will bring widespread rain and mountain snow to the region. Today, the best location will be from Missoula to the Canadian border. Butte and Bozeman will begin seeing widespread rain and mountain snow tonight and Thursday. Our 2 day rainfall totals will range from .25" to .50" for valley locations with .50" to 1.50" in the Bitterroot mountains. Rock and debris slides will be possible along highway 12 due to the copious about of rain.
Snow levels will be hover around 5000 feet in Glacier Park, 6000 feet across southwest Montana around Bozeman and 6500 feet in the mountains around Missoula. The passes that will see the possibility of some accumulating will be Lost Trail and Monida where one to three inches will be possible Wednesday into Thursday. By Thursday evening, snow levels may be low enough that snow could accumulate over Homestake and Bozeman passes.
A WINTER STORM WATCH is posted for Beaverhead, Madison, and Gallatin Counties. Big Hole Pass and Chief Joseph Pass could see up to a foot of snow. Three to 6 inches will be possible from Raynolds Pass, Targhee Pass, and West Yellowstone. Winds will gust to 30 mph creating reduced visibility due to blowing snow.
The precipitation ends early Friday and then we can enjoy a nice weekend. Some sunshine and highs in the upper 40s to mid 50s.
