Wider weather episode

An upper trough pushed several low pressure systems across the Pacific Northwest in the middle of April. The trough allowed for a much colder than normal air mass to settle into portions of eastern Washington and Oregon, allowing snow levels to drop to the surface across a majority of these areas. This ultimately resulted in snow accumulations in the mountains and lower elevations, with significant snow accumulations being observed in some mountain zones.
