Here is my weekly weather quiz question for the last time. “What is the “Santa Ana Wind?” Here is the correct answer. The Santa Ana Wind: In southern California, a weather condition in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions. A frontal system will be well offshore Next Saturday.
____________
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 tonight and Sunday, but not much change except for some cooling and maybe a light sprinkle. 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.
