An upper level low (Shaded “U” shape with blue arrows) will be in control of our weather far a while. A weak frontal system moved into the Pacific Northwest increasing the chance of rain with some warmer temperatures. Get ready for another frontal system behind it followed by yet another frontal system Monday.
