Snoqualmie Pass, Washington – The Washington Cascades may see brief periods of winter weather late next week, but current signals point to only a limited chance for snow, with no strong indication of a prolonged or high-impact mountain storm.
According to the National Weather Service Climate Prediction Center, the Cascades remain within a generally cool Pacific Northwest pattern from Saturday through the following Friday. While weak systems may move inland, cold air and deep moisture are not expected to align consistently enough to support heavy or sustained snowfall.
At pass level, including Snoqualmie and Stevens passes, occasional light snow is possible, especially during overnight or early morning hours when temperatures dip the lowest. Any accumulation currently looks modest, though brief slick conditions could develop on Interstate 90 and Highway 2 if snow coincides with traffic peaks.
Farther south near White Pass, similar conditions are expected, with light snow possible at times but limited overall impact. Lower elevations west of the Cascades are likely to see rain, while higher ridgelines may pick up light accumulations without significant travel disruption.
Washington State Department of Transportation advises travelers to remain alert when crossing Cascade passes, as even light snow can create hazardous driving conditions. While major winter impacts are not anticipated, updates may follow if colder air or stronger systems materialize later next week.
