The episode as NWS DLH wrote it up.
Heavy snow began across the northwest during the late afternoon and early evening. By midnight some areas had already received close to 6 inches of snow, and more fell overnight. Snowfall amounts were in the 4 to 8 inch range. Some areas received less than 6 inches of snow but the snowfall intensity and strong winds made travel conditions difficult.
