As the main upper-level trough begins to eject eastward into the
northern Plains during the next 24 hours, the heaviest snowfall is
forecast to impact areas from the eastern half of Montana into a
good portion of North Dakota as the snow over the northern Rockies
begins to taper off.  Bands of heavy snow with rates of 1 inch per
hour are forecast to produce total snowfall amounts of more than 8
inches with locally more than a foot across eastern Montana to
northwestern North Dakota.

The next Storm Summary will be issued by the Weather Prediction
Center at 900 PM MDT. Please refer to your local National Weather
Service office for additional information on this event.
