Heavy Snow — Lower Columbia, Oregon

2018-02-20 · Lower Columbia, Oregon

Event narrative

CoCoRaHS observer reported 5.1 inches in Rainier.

Wider weather episode

A cold low pressure system slid down the coast and stayed offshore, pulling cold air from east of the Cascades into western Oregon. This brought snow levels down to sea level, and moisture from the low pressure system meant snow down to the valley floor in the north Willamette Valley, and snow down to the Coast Range and Cascade Foothills farther south.
