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 system that moved northward through Oregon and the next one that’s on the way. The graphics for days 3-7 show that frontal system after it passed over us. Looks like some high pressure may be in our future in the middle of next week.
NOTE: Hoodoo Ski Area and Mt. Ashland Ski area are open. Not enough snow yet at Willamette Pass Ski Area.
