A strong low pressure system is forecast to move into the Pacific Northwest. With nearly continuous onshore flow, heavy rain is expected at lower elevations west of the Cascades across the Pacific Northwest and northern California. High winds and heavy mountain snows will also accompany this system. An extensive area of the offshore and coastal waters of Washington and Oregon have Storm and Gale warnings. Winter Weather Advisories are in effect for portion of the Olympics, Cascades, and Northern Rockies - with a Winter Storm Watch for the Sierra Nevadas. Some of the moisture will reach the northern Rockies by Tuesday as a surface low tracks inland. Temperatures will moderate across much of the Western U.S. ahead of the deep upper trough and will see temperatures rise above normal across the central and southern Plains by Tuesday. A weak front will pass through the Central Plains to the East Coast bringing light precipitation to a few areas. High pressure will build back into the region, which will keep cooler than seasonal normal temperatures through at least midweek.
