Winter storm warnings have been issued in four states: Oregon, Washington, California and Minnesota. In northwestern Oregon and parts of Washington, including the Willapa Hills, there will be light snow showers until midnight Friday. Cities impacted include Mary's Peak, Brooklyn, Sunset Summit, Wilson River Summit, Valsetz, and Horton.

Dozens of school districts canceled schools and state offices were closing early on Thursday in anticipation of snow expected to arrive by mid-morning, followed by freezing drizzle later.

Maine's Total Weather is timing out the snowstorm, which will also bring some fleet and freezing rain during the evening commute.
