On Wednesday at 4:01 a.m. the National Weather Service released an updated winter weather advisory valid from 5 p.m. until Thursday 5 p.m. for North Oregon Cascades, Cascades of Marion and Linn counties and Cascades of Lane County.

"Total snow accumulations up to 10 inches to 12 inches. Up to 17 inches above 5500 feet. Winds gusting as high as 35 mph," can be expected according to the weather service. "There is around a 20% chance that snow accumulation would exceed 12 inches at elevations above 4000 feet. For this scenario to occur, colder air would need to be present than what is forecast. This first system will be closely followed by a second frontal system so there may be minimal break between them."
