An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) is moving eastward away from us and the airflow is coming from the west. The onshore airflow is bringing more clouds our way. A frontal system (shown approaching the coast today) will bring the chance of rain between tonight and Saturday. Another frontal system will push into the Pacific Northwest Tuesday bringing increased chances for rain.
