An upper level high (Shaded “Arch” shape with blue arrows) will keep us in sunshine and warmer temperatures for the rest of the long Memorial Day holiday weekend. By Thursday a couple of frontal systems look like they will cool us down even if they don’t bring any precipitation. Next Monday a frontal system will be offshore headed our way.
