An Upper Level High Pressure Ridge  (“Arch” shape) is slowly moving in bringing more sunshine and warmer temperatures. It figures that the weather would get even better after the Holiday weekend. The graphics for days 1-3 show a frontal system that slid through the Pacific Northwest today. The graphics for days 3-7   Thursday through Monday show  a complex frontal system sliding through Oregon Thursday, then another front pushes through Saturday.
