An upper level low (Shaded “U” shape with blue arrows) will be in control of our weather for a while. A weak frontal system moved into the Pacific Northwest and fell apart. Get ready for another frontal system behind it (see previous graphic) followed by yet another frontal system Saturday and continuing the parade of storms a frontal system will approach the coast Monday.
