weak and transitory upper level ridge drifts west to east across the region on
Tuesday. A deep upper level low is also moving across the Pacific and ends up
about 500 miles west of Tillamook by late in the day. Look for dry weather but
increasing clouds later in the day. Mixing heights will be quite high and
