High pressure will dominate western Montana's weather through the weekend. It means sunshine during the day, cold temperatures at night, and the possibility of fog in the mornings. Expect persistant low cloud cover around the Flathead and Mission valleys with possible areas of fog and light lake-effect snow along highways 93 and 35.
Elsewhere, expect another subzero night after highs in the teens and low 20s. The Missoula, Swan, and Bitterroot valleys could see fog development Saturday morning with a chance for patchy fog this weekend in Soutwest Montana as well.
Light snow will be possible on Sunday around Yellowstone, but otherwise the weekend will be calm.
Milder weather will be back into the forecast next week with skies remaining mostly dry.
