Valentine's forecast calls for frigid temps in Western Washington, chance of snow, ice to the south

Cold temperatures continue to grip Western Washington, with wind chills as low as 10 to 20 degrees north of Seattle and all the way down to 15 degrees below zero in the mountain passes.

The National Weather Service in Seattle has issued a series of cold weather advisories until noon Thursday for the entire stretch of Western Washington along Puget Sound from the Canadian border south to Tacoma.

Those cold weather alerts are coupled with a winter weather advisory for a rain-snow mix moving into the area from the south Thursday afternoon into the evening.

The NWS advisories calls for up to two inches of wet snow through Friday evening in the Southwest Interior, Hood Canal area, and Lower Chehalis Valley, including the cities of Shelton, Montesano Elma, McLeary, Tumwater, Lacey, and Olympia.

Wet snow and wind gusts up to 40 miles per hour are expected until Friday morning in the East Puget Sound Lowlands including the cities of Monroe, Enumclaw, Maple Valley, Bonney Lake, Woodinville, and Prairie Ridge. Accumulation in those areas is expected to be up to an inch.

Tacoma is expected to get up to two inches of snow through Friday morning, and the NWS report warns of slippery road conditions Thursday night into Friday morning.

The heaviest precipitation is expected in the foothills of the North and Central Cascades, where snow accumulations of six to 12 inches are expected by 10 p.m. Friday night. The advisory also warns of ice accumulations that are expected to make roads, especially bridges and overpasses, slick and hazardous.
