First weekend of December will bring accumulating snow
We're tracking the strong likelihood of snow entering western Montana this weekend. Mountain passes will see the largest impact from this system, but valley locations may still see light accumulating snowfall.
Overnight low temperatures will fall into the lower to mid 20s in the Butte and Bozeman area. Kalispell and Missoula will stay in the upper 20s to near 30 degrees under mostly cloudy skies.
We'll see partly to mostly cloudy skies Saturday morning with high temperatures in the upper 30s to near 40 degrees. Rain and snow showers will begin Saturday afternoon in west central and northwest portions of the state. Snow levels will start near 3500 feet, but fall to 2000 feet Sunday morning.
Mountain passes west of the divide will see the most snowfall with 4 to 8 inches possible. Passes closer to the divide will see snowfall up to 4 inches. Valley locations will see light accumulating snowfall, up to 2 inches.
High pressure will build in next week, allowing for much drier conditions, plenty of sunshine, and daily chances of morning valley fog.
