An upper level low (Shaded “U” shape with blue arrows) will be in control of our weather for a while. The low will move through the Pacific Northwest with another stronger one following behind it. Here is a  frontal system following on the heels of the last one bringing more rain. Here is the continuing parade with another frontal system moving in Thursday and yet another frontal system next Sunday.
