SEATTLE – This week's first round of winter weather left thousands across Washington without power after gusting winds and snow snarled traffic and left up to 4-5 inches of snow in the Seattle area.

But round two of winter weather will move in later this week, lasting into the weekend. 

In Seattle, high temperatures will stick around the 30s bringing a daytime mix of rain and snow through the weekend.

While light snow accumulations fell Tuesday around downtown Seattle, 3-6 inches fell just a few miles away in the northern city suburbs and over toward the Cascade Mountain foothills.
