Wider weather episode

Strong westerly flow aloft continues to yield mild and windy conditions across much of the forecast area through Sunday. Occasional light snow, rain, and some mixed precipitation continues for the Northern Rockies through Saturday night, before transitioning to mostly snow thereafter. The most impactful weather remains above pass level. Colder air moves in aloft and snow accumulation becomes more efficient. High Wind Warnings for the Rocky Mountain Front and portions of North-central Montana expire at midnight but the windy conditions continue into Saturday. Although, the flow aloft will remain strong, warning criteria winds are not forecast at the surface.
