First Alert 48 Hour Forecast

WINTER WEATHER ADVISORY until 9 am Monday for all mountains and valleys west of the divide.  This includes the Missoula, Butte and Kalispell areas.  In general, 1 to 3 inches in the valleys with 3 to 6 inches in the mountains.

A surge of Pacific moisture will move through western Montana Sunday afternoon through Monday morning.  Most of the accumulating snow will be in the mountains west of the divide.  Light snow and flurries are likely in the valleys, with most accumulations of a trace up to 2, possibly 3 inches.  As milder air moves into the region, some of the valley snow may mix with rain and freezing rain.  Caution is advised on area roadways.

Lows in the 20s to around 30 with highs Monday in the 30s in Missoula and Kalispell to the lower 40s in Bozeman and Butte. 

Another surge of moisture will bring another round of precipitation in a similar fashion, with the heaviest in the mountains Monday night and early Tuesday.  Heavier snow may develop late Tuesday night and early Wednesday from West Yellowstone south into Wyoming and Idaho.

Arctic air will move into central Montana by Wednesday, but at this time it appears the coldest air will stay just east of NBC Montana.  It may get briefly colder along the divide and in Glacier National Park.
