An upper level high pressure ridge (Shaded “Arch” shape with blue arrows) has been keeping us in sunshine and warm temperatures. An upper level trough of low pressure  (Shaded “U” shape with blue arrows) will bring more onshore flow and cool us down a bit as we approach mid-week. A weak cold front will move through and at most only drop temperatures slightly Tuesday, Wednesday, and Thursday.
