Here is my new weekly weather quiz question. “What are “Sastrugi?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) weakens allowing clouds & possible showers. (Graphics may not be updated) 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 Saturday through Wednesday 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.
