The Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) is building offshore and will bring sunshine and warmer weather, but low pressure (Shaded “U” shape with arrows) isn’t too far behind to return the shower chances. The graphics for days 3-7 show the next storm systems that will approach and try to move through the Pacific Northwest Saturday through next Thursday.
