SEATTLE — Snow is expected to start Thursday night (around 9 p.m.) in Bellingham and roll south through the Puget Sound in the early morning hours (about 1 a.m.).
The snow will last until about 8 a.m. for most, but the precipitation stays as snow longer north of Seattle. The snowfall amounts will be around one inch for Seattle to Olympia near Puget Sound, two to three inches away from Puget Sound on higher hills (foothills), two to five inches up around Everett and points north, up to six inches for points east of Everett and Bellingham up in the foothills. The ski areas get 10 or more inches.
So, all of this adds up to a slick morning commute. Rain heads in quickly so we are talking about rain on top of snow. It will be all rain by midday (except for Bellingham). This looks like a fast snowfall event so evening commute should be OK. It will be windy, too, on Friday.
It will be mostly dry over the weekend — and Christmas looks dry and sunny.
