The National Weather Service forecasts 1 to 3 inches of snow Wednesday in most of Eastern Washington.
Forecasters say drivers can expect slick roads for a second day in many areas due to snow or freezing rain.
A series of frontal systems will bring more snow to the Inland Northwest through the weekend.
Heavy snow is expected in the mountains. Eight-to-18 inches could fall by noon Thursday in the Cascades, making driving difficult in the passes.
