An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) moves away as an Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) cleared us out for some sunshine for your Tuesday. That didn’t last because the chance of showers has returned. The graphics for days 1-3 show the next frontal systems headed our way. The graphics for days 3-7 show the frontal systems that will move through the Pacific Northwest Friday and Saturday and again next Tuesday.
