An Upper Level High Pressure Ridge (“Arch” shape) took over control of our weather for just one day. The graphics for days 1-3 show a cold frontal system moving through Oregon today. The graphics for days 3-7 Saturday through Wednesday show a cold front will be moving into Oregon Friday with another front offshore next then moving into the Pacific Northwest Wednesday.
