Here is my new weekly weather quiz question. What is the “PDSI?”
_______________
An Upper Level High Pressure Ridge (“Arch” shape) has been helping to pump unseasonably warm air over the Pacific Northwest, but that’s going to change. The graphics for days 1-3 show the complex frontal system that’s moving through. The graphics for days 3-7 Saturday through Wednesday show a the parade of complex frontal systems approaching the Pacific Northwest.
Note: Willamette Pass, Hoodoo, and Mt Ashland are all open for skiing. Check their web pages for details.
