The upper airflow (Shaded area with blue arrows) resumes sending Pacific moisture our way. A frontal system fell apart as it moved into the Pacific Northwest Tuesday so we had more sunshine than I expected. No complaints there. Another frontal system slides in today adding to the rain chances. This frontal system pushes through Oregon Saturday. Sunday another frontal system (position shown is Sunday) should move in Monday.
