Weather Synopsis for Tuesday & Saturday

An upper level low will continue to weaken as it drifts near the Oregon coast today, sending high clouds over the Pacific Northwest and light precipitation about as far north as the south Washington Cascades. Some moderate easterlies occurring as ridgecrest this morning from Stevens Pass area and south to Mt. Hood should ease this afternoon. A trailing upper level trough upstream quickly develop a frontal system that will pass through the Cascades mid-day Wednesday.  Rain and snow should develop mainly for the Olympics and north Cascades overnight and spread inland and south during the day on Wednesday. Some modest precipitation amounts are expected with this system for the volcanoes. Winds will also increase tomorrow as the frontal system impacts the area. Snow levels should end up in the 4500-5000 ft range by late Wednesday afternoon.
