An Upper Level Low Pressure Trough (“U” shape) over the Eastern Pacific that is moving closer to us keeps the onshore airflow over us holding the temperatures down to normal levels with shower chances. The graphics for days 1-3 show the frontal system that slid through the Pacific Northwest this morning and the next wave behind it. The graphics for days 3-7 Tuesday through Saturday show no frontal systems pushing into the Pacific Northwest until next Thursday.
