An upper level high pressure ridge (Shaded “Arch” shape) is moving closer to the Pacific Northwest. After tonight’s chance of showers and possible thunderstorms it’s back to more sunshine. A frontal system will be moving through Oregon next Saturday, possibly bringing a little rain for the Prefontaine Classic.
