Here is my weekly new weather quiz question. What is the “Spring Tide?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) will be following closely behind the Upper Level Low Pressure Trough (“U” shape) that’s moving away from us. The graphics for days 1-3 show a cold front that slid through Oregon Monday. The graphics for days 3-7 Friday through Tuesday show a frontal system moving through the coast inland next Monday and Tuesday.
