Weak high pressure (“arch” shape) is moving away from us as a strong trough of low pressure (“U” shape offshore) starts sending moisture to the Pacific Northwest by late Saturday. A frontal system has pushed through Oregon spreading some rain throughout the area. We will be between systems for a while, so enjoy the sunshine while it lasts. There will, of course, be some patchy morning fog in some areas. We’ll be back to the chance of rain by Saturday night.
