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