The graphics for days 1-3 show the frontal system that moved through today. An Upper Level High Pressure Ridge (Shaded “Arch” shape with arrows) takes over to take away the rain and start warming us up. The graphics for days 3-7 show surface high pressure also holding on through Friday when a cold front moves down from the north Friday night into next Saturday. Then another front approaches the coast next Sunday.
