An upper level Low (Shaded “U” shape with blue arrows) moves toward us bringing an increase in marine airflow from the West and that brought a change in our weather to a chance of showers. A frontal system swings into the Pacific Northwest. It’s back to sunshine and no rain starting Friday afternoon as High Pressure takes over to dry us out and warm us up.
