Wider weather episode

Beginning during the evening of January 15th and continuing through the 16th a warm front pushed north through eastern Washington. The East Slopes of the Cascades and the adjacent Columbia Basin zones were under the deepest moisture feed and received heavy snow accumulations. The remainder of the Columbia Basin received generally 1 to 3 inches of snow accumulation. The warm front stalled near the Canadian border which promoted a longer period of snow over the northern mountains of eastern Washington where another region of heavy accumulations resulted.
