An Arctic cold front and upper level disturbance moved south across Wyoming.  Strong upslope north to northeast winds produced moderate snowfall amounts over much of southeast Wyoming.  The heaviest snowfall occurred over the Snowy and Sierra Madre mountains with 6 to 12 inches reported.  The combination of winds and snow caused hazardous travel conditions along Interstate 80 from Cheyenne to Arlington, and Interstate 25 from Cheyenne to Wheatland.
