An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) continues to control our weather for the time being. The graphics for days 1-3 show the front that moved through and the next one approaching the coast Wednesday. An Upper Level High Pressure Ridge will start taking over Thursday bringing dry and sunny weather at least for a while. The graphics for days 3-7 show the frontal system that will return the clouds and at least a slight chance of showers to the Pacific Northwest by Saturday.
