A series of Pacific fronts and troughs brought another long lived snow event to western Wyoming. The heaviest snow fell in the Tetons and adjacent Jackson Valley. Snowfall amounts in the Tetons over 30 inches were common. The highest amount was 63 inches of new snow at the Jackson Hole Ski Resort. Snowfall amounts in the Jackson Valley generally ranged from 12 to 30 inches. Over three feet of new snow fell in Yellowstone Park with over two feet in portions of the Absarokas.
