An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) is moving down from the Gulf of Alaska and has brought a change in our weather pattern to cloudier, much cooler, and wet. The graphics for days 1-3 show frontal system that moved through Friday bringing rain and cooler temperatures. The graphics for days 3-7 show the frontal systems that will approach and then move through the Pacific Northwest Monday through next Friday.
