2018-02-20 · Central Columbia River Gorge, Washington

Event narrative

CoCoRaHS observer 2 miles west of Underwood reported 5.1 inches of snow.

Wider weather episode

A low pressure system slid down the coast and stayed offshore, pulling cold air from east of the Cascades into southwest Washington. This brought snow levels down to sea level, and moisture from the low pressure system meant snow down to sea level around Vancouver and along the lower Columbia River.
