The "sticking" snow will likely arrive after dinner Tuesday for parts of Seattle and northward to the border. The Winter Storm Watch in effect until Wednesday morning also includes the Strait of Juan de Fuca, the islands and the North Coast.
One-four inches of additional snow is expected tonight in the Seattle area, with up to five inches in Everett and eight inches of snow in Port Angeles, according to the National Weather Service. In the foothills, Cascades and South Sound, it's a Winter Weather Advisory due to the lesser amounts expected.
The snow is expected to end before the morning commute Wednesday, leaving motorists driving through the icy aftermath.
There's also a strong wind threat across the Cascades, foothills and East Puget Sound lowlands Wednesday afternoon, which could cause tree damage, power outages, hazardous crosswinds, dangerous marine conditions and possible blowing snow, according to the National Weather Service.
The next system working is on a track that will help bring in warmer air from the south to help us get out of the freezer on Thursday. A rain-snow mix is likely for Thursday, with more seasonal lowland rain and mountain snow looking likely for Friday and the weekend.
