Valley inversions will persist in several locations across western Montana through Tuesday. Many areas have transitioned from fog to low stratus, but the Missoula and Bitterroot Valleys can expect fog to last through the morning commute. Patchy freezing fog will create a black ice situation on our roads. Travelers should pay close attention to changing ROAD CONDITIONS.
Under these inversions, temperatures will remain cold. Highs will be in the teens and 20s for the Missoula and Kalispell areas through Tuesday. Ample sunshine will warm temperatures in Butte and Bozeman to the mid to upper 30s.
Inversions will begin to weaken Wednesday. Clouds and the threat of rain and snow will begin to increase late Wednesday.
Widespread snow is expected late Thursday and Friday. Mountain passes will see 5 to 10 inches of snow. Valley locations could see 1 to 3 inches. Track our next weather maker right along with us by downloading our NBC Montana News and Weather Apps.
Valley inversions return for the weekend.
