An atmospheric river brought an abundance of moisture to the Western Slope. This, paired with the passage of an upper level trough across the Northern Rockies and associated cold front, resulted in moderate to heavy snow for the mountains. Upwards of 1 to 2 feet of snow fell on the favored slopes. Mild air associated with the atmospheric river kept snow levels high with mostly all rain or a rain/snow mix in the valleys. Winds gusted in excess of 60 mph at times in the mountains.
