of heavy snow with rates of 1 inch per hour are forecast to
produce additional snowfall amounts of 3-6 inches for central
North Dakota into portions of northwestern Minnesota and 6-8
inches from far northeastern North Dakota into far northwestern
Minnesota through late Friday morning.

The next Storm Summary will be issued by the Weather Prediction
