An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) has taken over bringing more sun and no precipitation, but it has given us cold overnight lows. The graphics for days 1-3 show a frontal system moving into the Pacific Northwest. Warm front first then the cold front. The graphics for days 3-7  show a backdoor cold front sliding down from the south Saturday. More frontal systems are shown off California’s shore next Tuesday.
