An Upper Level Low Pressure Trough (“U” shape) continues sending surface fronts over Pacific Northwest. The graphics for days 1-3 show more frontal activity moving through Oregon. The graphics for days 3-7 Sunday through Thursday show the parade of 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.
