Winter Storm in South Washington Cascades, Washington

Winter Storm February 11, 2021 – February 13, 2021 · South Washington Cascades, Washington

What the National Weather Service wrote

Given the reports of 10-20 inches of snow in the Gorge, and over two feet around Mount Hood, it seems reasonable that the South Washington Cascades would see similar totals or more.

The wider storm

A deep upper trough drove an arctic airmass into southwest Washington. As multiple Pacific fronts moved over the area, a major elevation winter storm with heavy snow and freezing rain occurred over a multi-day period. This was a major, widespread, multi-faceted winter storm that caused major problems across the forecast area, even (and especially) in the lowlands.
