With temperatures dropping into the mid-20s to lower 30s precipitation could start as snow in most places with levels in the 500 to 1000 foot range. Places with a little elevation like North Bend/Snoqualmie Ridge could see a wet inch of snow before the precipitation turns over to rain. Precipitation will be light to start so will keep the start time of the winter weather advisory for the Cascades at 4 pm.
