A vigorous Pacific low pressure system brought widespread heavy snowfall and northerly winds up to 50 mph as it moved across the central Rockies.  Storm total snow accumulations up to two feet were observed across southeast Wyoming.  The combination of falling snow and strong winds produced considerable drifting snow, which resulted in very low visibilities and snow packed roads.  Numerous highways, including Interstate 80 from Rawlins to the Nebraska border were closed.
