Here is my weekly weather quiz question. What is a “Stationary Front?”
____________
An Upper Level High Pressure Ridge (“Arch” shape) has taken over control of our weather. The graphics for days 1-3 show a weak frontal system moving through today. The graphics for days 3-7 Monday through Friday show no fronts sliding through the Pacific Northwest through the period until a cold front will be moving into Oregon next Wednesday and Thursday, then another front will be to our northwest next Friday.
