Snow to Spread Across West as Temperatures Plunge

An active weather pattern is in place across the western United States, AccuWeather forecasters say, and the arrival of a storm in the Northwest will eventually result in widespread impacts from California to the central and southern Rockies.

An area of low pressure was diving southeastward over the interior West on Tuesday. As the storm strengthens will moving into the Southwest region, areas of snow will break out and become locally heavy from the Sierra Nevada to the Rockies in Colorado and the various ranges in northern Arizona and New Mexico.
