An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) tilts enough to bring cooler air to us from the north and northeast. No immediate chance of precipitation though. The graphics for days 3-7 show a frontal system pushing into California Wednesday then another front approaching the Pacific Northwest Saturday to move in next Sunday. There is even another frontal system located well offshore Sunday heading our way next week.
