An upper level ridge of high pressure (Shaded “Arch” shape with blue arrows)  will be weakening today as an upper level low (Shaded “U” shape with blue arrows on previous graphic) and a frontal system will approach the coast and bring back much cooler temperatures and the slight chance of rain. Another front (position shown is past us on Friday) will move toward us late in the week to keep the rain chance around.
