Here is my new weekly weather quiz question. “What are “Sastrugi?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) takes over for warming, but not for long. The graphics for days 1-3 show a frontal system moving through Oregon Wednesday with another right behind it. The graphics for days 3-7 Friday through Tuesday show no frontal systems pushing through the Pacific Northwest until a complex frontal system will be moving through Oregon between Saturday and next Sunday. Yet another front headed our way next Tuesday.
