A strong Pacific low pressure system moved across the central Rockies and produced periods of moderate to heavy snow along with gusty north to northeast winds of 35 to 45 mph.  The combination of falling and blowing snow produced near whiteout conditions across much of southeast Wyoming.  Interstates 25 and 80 were closed for several hours.  Snow totals ranged from four to 16 inches, heaviest over the Snowy and Sierra Madre mountains.
