________________
An upper level high pressure ridge (Shaded “Arch” shape) is moving closer to the Pacific Northwest. As the high moves closer to us the chance of showers returns Friday because of an increase in onshore airflow and a frontal system that is approaching from the northwest.  Another frontal system will be approaching the Oregon coast by Sunday, bringing a little chance of rain out ahead of it and along it for Saturday and again on Sunday and Monday.
