The National Weather Service has issued a Winter Weather Advisory for Sunday in Northwest Oregon.
Snow is expected and freezing rain is possible. Snow accumulations of up to 3 inches and ice accumulations of a light glaze.
Accumulations should be greatest for elevations above 500 feet, as well as western portions of Washington and Columbia Counties. Winds gusting as high as 40 mph near the Columbia Gorge, especially this morning.
Precipitation should transition to all snow this morning. After that, expect a brief period of sleet this afternoon before precipitation transitions back to rain. Cold air trapped outside of the major metropolitan areas will likely result in icy pockets persisting well into the day today and possibly into tonight.
