The episode as NWS ARX wrote it up.
Freezing rain caused widespread 1/4 to 1/2 inch accumulations of ice, before changing to snow. Snow accumulations of 2 to 4 inches were common, which only added to the already hazardous traveling conditions. In addition, strong northwest winds of 20 to 30 mph caused considerable blowing and drifting snow, creating near blizzard conditions.
