An Upper Level Low Pressure Trough (Shaded “U” shape with blue arrows) takes over bringing onshore airflow which means more clouds and cooler with showers chances. The graphics for days 1-3 show the frontal system that will move through Oregon Wednesday. There graphics for days 3-7 show that after Friday no frontal systems will move through the Pacific Northwest through next Monday.
