Wintry Mix for Portions of I-90, I-84, and US-12

A pre-Thanksgiving winter system will produce snow accumulations across the Cascade crest and the Blue Mountains beginning late Tuesday morning through Tuesday night. Heaviest snow accumulations will be along the Washington Cascade crest, and interior portions of the Blue mountains north of Interstate 84. This system will also bring a chance of light freezing rain across the Washington Cascade east slopes, higher elevations of the Yakima valley, northern Blue mountains, and portions of the Kittitas, Grande Ronde, and Wallowa valleys Tuesday night. Portions of I-90, I-84, and US-12 in these areas will be impacted.
