An upper level Low (Shaded “U” shape with blue arrows on previous graphic) starts moving toward us and that means a change in our weather. A surface frontal system moves through the Pacific Northwest between Wednesday and Thursday enhancing the chance of showers. It’s back to sunshine starting Saturday as High Pressure takes over.
