An Upper Level Low (Shaded “O” shape with arrows) keeps its hold on the Pacific Northwest. Its center is to our south, but it will move slowly to the north Wednesday keeping the chance of thunderstorms in the Cascades. The graphics for days 3-7 show a frontal system slides down to approach the coast Friday and another front moves out of the Gulf of Alaska heading our way Sunday night into Monday. Surface high pressure is shown in the Pacific moving toward the Pacific Northwest.
