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) clears us out for some sunshine for your Tuesday. That won’t last because the chance of showers returns tonight. The graphics for days 1-3 show the weak frontal system that brought more clouds and a chance of showers. The graphics for days 3-7 show the frontal systems that will move through the Pacific Northwest Friday and Saturday.
