Spokane, WA – A powerful cold front is set to sweep into eastern Washington late Wednesday, bringing a mix of heavy mountain snow and persistent valley rain. This storm is expected to impact several major mountain passes, including Stevens Pass, Washington Pass, and Sherman Pass, causing hazardous travel conditions from Wednesday evening through Friday. Travelers should prepare for delays on these routes as snow accumulation and rain create slick, challenging roads.
According to the National Weather Service, snowfall will begin Wednesday night at elevations above 3,500 feet, with snow levels dropping to about 3,700 feet by Thursday. Accumulating snow in the higher elevations may lead to delays and dangerous driving conditions on Stevens, Sherman, and Washington passes. Light to moderate rain will also spread across lower elevations, extending into the Idaho Panhandle, where wet conditions may persist into the weekend.
By Thursday, temperatures in the Spokane area will peak at 49°F, with a high probability of rain throughout the day. Rainy and foggy conditions are expected to continue through Friday, with evening temperatures dropping to the mid-30s. Drivers should anticipate reduced visibility and slippery roads, especially on exposed mountain stretches and areas with higher snowfall.
Heading into the weekend, conditions may stabilize slightly with fog patches and lighter rain. However, lingering wet conditions on Friday night and possible snow down to 3,800 feet could continue to impact roadways and travel. Motorists are urged to monitor weather updates and consider alternative routes if traveling through the mountain passes.
