Here is my weekly weather quiz question. What are “Parhelion“?
_________________
An Upper Level High Pressure Ridge (“Arch” shape) has moved closer to us which means the freezing precipitation will be gone. Melting the ice may take a while. The graphics for days 1-3 show the front currently sagging into Oregon and becoming stationary to our south. The graphics for days 3-7 Monday through Friday show a the parade of frontal systems approaching the Pacific Northwest.
Note: Due to the heavy snowfall in the area Willamette Pass, Hoodoo, and Mt Ashland are all open for skiing, if you can get there through the snow and downed trees. Check their web pages for details.
