Forecast Discussion: Despite plenty of sunshine on Saturday, things will remain a little too cool for ozone to rise above the good range. More moderate ozone concentrations are likely for Sunday into Memorial Day as winds move to the southwest, humidity increases, the air turns warmer, and mixing is limited. Temperatures by Memorial Day can move past the 80 degree mark. Any afternoon and evening convection Monday looks to be more limited. Ozone levels will then decrease towards the middle of next week with increasing afternoon and evening thunderstorms, as well as a possible south to southeast maritime influence.---McAuliffe
