An Upper Level High Pressure Ridge (“Arch” shape) continues sending moisture from the northwest to the Pacific Northwest. The graphics for days 1-3 show a little frontal over the Pacific Northwest. The graphics for days 3-7 Thursday through Monday show frontal activity continuing through the period.
Note: Ski Report: Willamette Pass, Hoodoo, and Mt. Ashland are all open for the ski season. Check their Web sites for specific mountain conditions and hours of operation.
