Possible Fog and Stratus Later This Week

Strong valley inversions will bring a chance of fog and low stratus to the Northern Rockies from Wednesday through at least Friday (Nov. 11–13). Areas across North-central Idaho and Western Montana valleys—including major routes like I-90, US-93, US-2, US-12, US-95, MT-200, MT-83, and MT-56—may experience localized travel hazards caused by low visibility and icy road surfaces from freezing fog. Allow extra travel time and use low-beam headlights when driving through valley fog.
