Upper Level High Pressure (Shaded “Arch” shape with blue arrows) offshore gives us colder nighttime temperatures which could produce freezing rain making some roadways slippery. The graphics for days days 1-3 show the complex frontal system with a warm front moving northward through Oregon Wednesday into Thursday. The graphics for days 3-7 show new complex frontal systems approaching the Pacific Northwest Saturday through next Wednesday.
NOTE: Hoodoo Ski Area is open.
