Our next round of wet weather will bring snow back to the lower elevations overnight.
Winter Weather Advisories are in effect from 11 pm Saturday through the morning hours Sunday for Marias Pass, Lookout Pass, Yellowstone Park, Lolo Pass, Lost Trail Pass, MacDonald Pass, and areas from Butte to Drummond on I-90. Snowfall on passes will be in the neighborhood of 2 to 6 inches, with 1 to 3 inches of snow possible around Butte and other high elevation areas.
Most lower elevation areas will see light snow that won't stick or a mix of rain and snow overnight. Some areas, such as Dillon, Three Forks, and possibly Missoula, could see prolonged dry periods due to downslope winds.
All areas will transition back to rain as we warm up on Valentine's Day. Highs will be in the 40s.
Another wet system moves in Sunday night with heavy rain likely along the state line with Idaho through early Tuesday. Temperatures remain above normal for the week ahead, with more moisture expected Thursday.
