Here is my new weekly weather quiz question. “What is the “Santa Ana Wind?”
____________
An Upper Level Low Pressure Trough (“U” shape) is moving eastward away from the Pacific Northwest to be replaced by an Upper Level High Pressure Ridge (“Arch” shape). The graphics for days 1-3 show no frontal systems moving through the Pacific Northwest. The graphics for days 3-7 Friday through Tuesday show no frontal systems pushing through the Pacific Northwest until a cold front moves through next Sunday.
