A cool trough of low pressure will move over the area on Saturday. There will be scattered showers in western Washington, as snow falls in the mountains. Wet snow is also possible in parts of eastern Washington, including the Pullman and Spokane areas. Although there will be a slight chance of showers, central Washington will be mostly dry and breezy with seasonal temperatures this weekend. Sunday will be a drier day, with only a chance of showers lingering west of the Cascades.

Subfreezing overnight low temperatures are likely in western Washington early next week. Temperatures on Monday or Tuesday morning could be in the 20s in inland, rural areas, especially if skies are clear and winds are calm. Following dry conditions early next week, another storm system will bring a chance of rain, mountain snow, and wind to Washington by mid week. Temperatures will be generally near to slightly below average. The mildest weather should occur around mid week due to increased mixing and slight warming in association with the mid week storm system. Although no arctic cold is expected, it appears that Washington is beginning a period of cool and at times unsettled weather. The best chance for any snowfall would be at higher elevations, in the north, and at night.
