A potent low pressure system tracked east across the central Rockies and high plains, while an arctic front surged south through the region.  Snow developed west of the Laramie Range and became moderate to heavy at times over the higher elevations. Periods of light to moderate snow occurred from the Laramie Range east to the Nebraska border.  Strong northerly winds of 40 to 60 mph created periods of very low visibility in blowing snow.  Consequently, Interstate 80 was closed from Rawlins to the Nebraska border.  Snowfall totals ranged from a few inches to as much as a foot over the Snowy Range.
