An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) is still controlling our weather but a couple of frontal systems will slip through. The graphics for days 1-3 show a frontal system moving through the Pacific Northwest today and another arriving Friday. The graphics for days 3-7  show a frontal system just offshore next Wednesday.
