Wider weather episode

A long-lived winter storm moved across western and central Wyoming and brought heavy snow to many areas, especially the western mountains. The highest accumulations were in the Salt River and Wyoming ranges where up to 30 inches fell at the Blind Bull SNOTEL. Accumulations of 1 to 2 feet were common across the higher elevations of Yellowstone National Park, and the Teton and Wind River ranges. In the lower elevations, the snow mixed with rain at times, limiting accumulation. Maximum accumulations in the lower elevations topped out around 1 foot in Bondurant and at 7 inches in Green River. The storm was accompanied by gusty northeast wind and arctic temperatures. The two combined to create wind chill readings well below zero.
