A cold front swept across western and central Wyoming from Friday into Saturday and brought heavy snow and difficult travel conditions to many areas. The heaviest snow fell in Absarokas where 21 inches fell in Pahaska. A foot or more of new snow also fell in portions of Yellowstone Park and the Tetons. The heaviest snow in the lower elevations fell in northern Wyoming. Some notable amounts include 10 inches at Bondurant, 9 inches in Cody and 10 inches in Thermopolis. Even in areas that received less snow, the combination of snow, gusty wind and black ice from rapidly falling temperatures brought very difficult travel conditions. Interstates 25 and 80 were shut down for a time, as well South Pass over the Wind River Mountains.
