Skies will gradually clear Thursday night, leading to cold temperatures overnight. Temperatures will fall into teens and 20s inland, and near 30° along the Coast. Black ice is a big concern for the Friday morning commute as temperatures drop well below freezing and the water on the roads from the recent snow melt refreezes. Some patchy freezing fog is also likely in the inland valleys, which will increase slick conditions across the area.
Showers will return Friday evening, with snow mainly staying above 1,000 feet. A Winter Storm Warning is in effect for the Douglas County Cascades above 2,000’, where 2-8” of snow is expected. A Winter Weather Advisory is in effect for Douglas and Coos counties from 1,000-2,000’, where 1-3” of snow is expected.
Pass Conditions: Chains or traction tires are required to get across Willamette Pass. Carry chains as you cross Santiam Pass or HWY 138.
