Event narrative

A CoCoRaHS Observer 2.1 miles west of Underwood reported 4.4 inches of snow.

Wider weather episode

Low pressure system moving into the Pacific Northwest pulled cold air from the Columbia Basin west of the Cascades, through the Columbia River Gorge. As this system started to bring moisture and precipitation into SW Washington, temperatures were around or below freezing, allowing for a mix of snow and ice to fall all the way to sea level around the Vancouver Metro, Lower Columbia River Valley, and in the Columbia River Gorge.
