Here is my weekly weather quiz question for the last time. “What is the “Santa Ana Wind?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) brings Summer heat. The graphics for days 1-3 show a frontal system approaching the coast Saturday Then pushing into Oregon Saturday and Sunday, but not much change except for some cooling. The graphics for days 3-7 Tuesday through Saturday show no frontal systems pushing through the Pacific Northwest until a cold front moves through between Wednesday and next Thursday.
