What happened
The episode as NWS RIW wrote it up.
A strong Pacific storm system dropped very heavy snow across western Wyoming. Snowfall amounts of 2 to 3 feet were common above 8000 feet. Lower elevations west of the Continental Divide received 1 to 2 feet of new snow through the period. Snowfall combined with wind gusts to 40 mph, dropped surface visibilities to near zero in some areas creating treacherous travelling conditions.
