What happened

The episode as NWS RIW wrote it up.

A strong upper-level storm system pummelled extreme western Wyoming with significant snowfall accumulations. The western valleys generally received 4 to 7 inches. Meanwhile the mountains of western Wyoming received generally 12 to 22 inches of new snow accumulation. Strong westerly winds approaching 35 mph at mountain-top combined to make travel treacherous across mountain passes throughout the event.
