Here is my new weekly weather quiz question. “What is a “Rip Current?”
____________
An Upper Level Low Pressure Trough (“U” shape ) is approaching the West Coast bringing unsettled weather. The graphics for days 1-3 show a frontal system moving into Oregon Tuesday. The graphics for days 3-7 Friday through Tuesday show a cold front that will push into the Pacific Northwest Friday and Friday night. A complex frontal system will be well to our Northwest next Tuesday.
