The low pressure system off the coast of Oregon is expected to
move southward through tonight and is forecast to move onshore
into southwestern Oregon on Sunday.  Snow currently over the
Pacific Northwest is expected to gradually taper off from north to
south tonight as the system moves farther to the south. 
Meanwhile, the snow will overspread the higher elevations of
northern California through tonight including the Sierra Nevada
before becoming more scattered in nature on Sunday. An additional
inch or two of snow is possible across the lower elevations of
Washington and Oregon through tonight, with up to 8 inches
possible over the higher elevations of the interior sections.
Farther south, up to 10 inches of snow is expected for the higher
elevations of northern California through tonight.  The Sierra
Nevada is expected to see more than two feet of snow through
Sunday evening.  The snow will also spread into the Intermountain
region where up to a foot is possible through tonight.  Another
system is forecast to arrive Sunday night, bringing additional
snowfall into the Pacific Northwest.

The next storm summary will be issued by the Weather Prediction
Center at 700 PM PST. Please refer to your local National Weather
Service office for additional information on this event.
