Upper Level High Pressure (Shaded “Arch” shape with blue arrows) continues sending us waves of moisture. The graphics for days days 1-3 show the complex frontal systems zig zagging their way through the Pacific Northwest, but still keeping the colder air well to our north. The graphics for days 3-7 show a break from major frontal systems into the end of next week.

NOTE: Hoodoo Ski Area and Mt. Ashland Ski area are open. Not enough snow yet at Willamette Pass Ski Area.
