Here is my new weekly weather quiz question. “What is the “Santa Ana Wind?”
____________
An Upper Level Low Pressure Trough (“U” shape) allows frontal movement through the Pacific Northwest. The graphics for days 1-3 show no frontal systems moving through the Pacific Northwest. The graphics for days 3-7 Thursday through Monday show no frontal systems pushing through the Pacific Northwest until a cold front moves through next Sunday.
