The low pressure system is forecast to track east across the
north-central Rockies tonight and Sunday. Snow will continue to
fall heavily at times, in particular over portions of eastern
Washington, northern Idaho, and central to western Montana. An
additional 1 to 2 feet of snow is expected to fall over areas of
western Montana through Sunday night with locally higher amounts
in excess of 3 feet over the highest elevations. Over northern
Idaho, another 6 to 12 inches of snow is expected to accumulate
through Sunday night. Parts of the Cascades will also receive an
additional 5 to 10 inches of snow while portions of the northern
Sierra Nevada will pick up several inches on average with locally
higher amounts possible. Strong winds will result in poor
visibility with blowing snow and drifting snow.

The next Storm Summary will be issued by the Weather Prediction
Center at 300 AM MDT. Please refer to your local National Weather
Service office for additional information on this event.
