Wider weather episode

A low tracked into Prince William Sound on Dec 12 as it rotated around a deep upper-level trough centered over Western Alaska. Snow spread west from the Copper Basin as the trough became northwest-southeast oriented. Out west, the upper-level trough contributed to a strong push of cold air across the Bering Sea, which lead to blowing snow with widespread snow showers across the Alaska Peninsula.
