Wider weather episode

A very active week of frequent snow storms across the Inland Northwest culminated with another warm front passage which concentrated heavy snow over the far western Columbia Basin during the day of January 18th. Snow levels rose during the day as the warm front passed through from south to north allowing partial melting of much of the morning accumulations. The Cascades received generally 3 to 5 inches of wet snow with local accumulations to around 8 inches near the Cascade crest. Elsewhere in eastern Washington, farther away from the deepest moisture feed and also subject to warming during the day generally 1 to 3 inches of wet snow was noted.
