Advisories: None at this time.

A weak high pressure ridge (“Arch” shape on yellow line) will be moving away from the Pacific Northwest with a low pressure trough (“U” shape on the yellow line) pushing in behind it. That means it’s back to a wet weather pattern for the workweek. A frontal system will move through today bringing more clouds and rain to the area.
