Snow is in the forecast for Friday morning throughout northwest Oregon and southwest Washington, with some areas above 1,000 feet elevation seeing as much as three inches of accumulation, weather officials say.

Morning commuters in the Portland area should expect to see snowflakes in the air, but areas below 1,000 feet are expected to see little to no accumulation, according to Jeremiah Pyle, a meteorologist with the National Weather Service in Portland. Roads closer to the valley floor may be too warm for much snow to gather, he said.

Snowfall in the Portland area is expected to begin between 3 a.m. and 6 a.m. and turn to rain by mid-morning, Pyle said. Rain will continue on and off throughout the day with temperatures in the mid- to high-40s.

Areas above 1,000 feet elevation could see 1 to 3 inches of snow Friday, Pyle said. The Eugene area could see snow as early as around midnight, he said.
