Olympia, WA – Washington travelers should brace for a stormy holiday week with heavy rain, gusty winds, and significant mountain snow expected from Wednesday through Black Friday, according to new national weather maps from the Weather Prediction Center.
According to the WPC, a strong Pacific moisture plume will push into Western Washington early Wednesday, bringing widespread rain to the coast, Seattle metro, Puget Sound, and the I-5 corridor. Rain may be heavy at times, slowing travel from Bellingham to Olympia. Along the coast and in the Strait of Juan de Fuca region, winds could gust strongly enough to produce tree limbs down and spotty power issues.
Meanwhile, Cascade pass travel becomes increasingly hazardous Wednesday afternoon. Snow intensifies over Snoqualmie Pass (I-90), Stevens Pass (US-2), and White Pass (US-12), with accumulating snow creating slippery conditions and periods of low visibility. The heaviest snow is expected above 3,500–4,000 feet, though snowfall may reach pass level frequently.
Thanksgiving Day (Thursday, November 27, 2025) continues the unsettled pattern. Western Washington remains wet with off-and-on rain and cooler temperatures. In the mountains, steady snow is likely throughout the day. Eastern Washington—including Spokane, the Tri-Cities, Yakima, and Walla Walla—sees colder air and scattered snow showers, especially during the morning.
By Black Friday (November 28, 2025), additional cold air reinforces snow potential in the Cascades. Early shoppers and travelers crossing the mountains should expect ongoing hazards: icy pavement, blowing snow, and intermittent heavy snow bands. Valley areas west of the mountains see lingering showers, while Eastern Washington stays cold with flurries possible.
Drivers through the Cascade passes should allow extra time and check updated DOT advisories frequently
