Areas of snow will create a slick and slippery Monday morning commute.
The Flathead and Mission Valleys have the potential to receive 2 to 4 inches of snow. I would include Butte in this projection as well.
The Missoula and Bitterroot Valleys could possibly pick up 1 to 3 inches of snow. Cities like Bozeman and Dillon are likely going to fall in this spectrum too.
The higher elevations and mountainous terrain could accumulate close to 6 inches of fluffy and light weight snow.
Drive carefully and courteously.
