An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) nosed into the Pacific Northwest to give us relatively dry conditions to start your workweek. An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) slides eastward bringing us the chance of  showers by Tuesday night into Wednesday. The graphics for days 1-3 show the next frontal system moving in Wednesday. A High Pressure Ridge takes over late in the week for a return to drying. The graphics for days 3-7 show the frontal systems approaching the Pacific Northwest Saturday and next Monday.
