The wider storm

Back-to-back low pressure systems dropping south along the coast of British Columbia and Washington brought cold air south into SW Washington as well as plenty of moisture. Locations in the Columbia Gorge saw 1 to 2 feet of snow. At lower elevations, a near stationary frontal boundary Monday night into Tuesday morning dropped several inches of rain over portions of Cowlitz County causing flooding.
