An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) is controlling our normal Fall weather pattern. Much cooler air just moved in from the north. The graphics for days 3-7 show surface disturbances sliding through Oregon. There is a possibility of some serious rainfall, particularly at the coast, coming to us from moisture moving across the Pacific Ocean from two tropical disturbances.
