In Spokane, wet, heavy snow snapped tree branches and took out power lines. Avista Utilities was restoring power to 32,000 customers Wednesday. Driving conditions are deteriorating across Montana and northern Wyoming as ice and blowing snow covered roadways.
Up to 2 feet (0.61 meters) of snow is expected to fall in the mountains, and up to a foot in lower-elevation towns and cities. The storm is expected to bring the first snow of the season to Denver by Thursday.
