Here is my weekly weather quiz question. What is “Yellow Snow “? (No it’s not that!)
The Jet Stream is sending an Atmospheric River full of moisture from over the Pacific Ocean right into the Pacific Northwest. The graphics for days 1-3 show a frontal system moving through Oregon between tonight and Saturday. The graphics for days 3-7 Monday through Friday show the parade of frontal activity continuing Wednesday through Friday.
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.
