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

higher elevations of northern California through tonight including
the Sierra Nevada before becoming more scattered in nature on
Sunday. An additional couple of inches of snow is possible today
across the lower elevations of Washington and Oregon through
tonight, with up to 10 inches possible over the higher elevations
of the interior sections. Farther south, more than a foot 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 tonight.  The snow will also spread into
the Intermountain region with up to 8 inches possible through
tonight.  Another system is forecast to arrive on Monday, bringing
additional snowfall into the Pacific Northwest.
