The graphics for days 1-3 show the weak frontal system dropping in for a quick visit Saturday. An Upper Level High Pressure Ridge is taking over bringing dry and sunny weather at least for a while. An Upper level Low Pressure Trough returns the chance of increasing clouds and and the small chance for showers tonight and Saturday, then high pressure takes control again. The graphics for days 3-7 show the frontal systems that will be affecting the West Coast next Tuesday and another front well to our north Thursday.
