A Pacific trough and cold front moved across Wyoming and brought heavy snow to the northwestern portions of the state. The heaviest amount of snow fell in the Tetons with 26 inches at the Jackson Hole Ski Resort the heaviest amount. Over a foot of snow fell in portions of Yellowstone Park, the Jackson Valley and the Absarokas. In central Wyoming, wind was the main hazard from the storm. Several wind gusts of hurricane force occurred along South Pass in the Wind River Mountains with a maximum wind gust of 86 mph. Wind gusts over 65 mph were also reported in the Lander Foothills and Natrona County. The snow and high wind disrupted travel, resulting in the closure of several roads for many hours.
