What happened

The episode as NWS BOI wrote it up.

A cold North Pacific storm system tracked inland through Southeast Oregon and Southwest Idaho, spreading heavy snow across the region. Sherriff's department officials, along with NWS spotters, in Baker County reported 12 inches of snow in Sumpter and 7.5 inches in Halfway. A power outage resulted from the heavy snow in Sumpter when a load of heavy snow slipped off power lines causing them to bounce and strike each other, creating a short in the line. Power was restored within one hour.
