Upper level high pressure (Shaded “Arch” shape with blue arrows) cleared us out for a while returning the sunshine. An upper level low (Shaded “U” shape) is taking over pushing a frontal system through the Pacific Northwest bringing rain and dropping temperatures drastically today. It looks like there will be just a slight chance of showers for the long Memorial Day Holiday weekend.
