Forecast Discussion: High pressure coming eastward from the Ohio valley is bringing a mostly sunny sky this afternoon with low levels of ozone. An adequate amount of mixing in the boundary layer will keep ozone levels in the good range for the day Saturday with a pop up thundershower in spots. Very warm and more humid Sunday with periods of clouds and sunshine. With lighter winds, ozone will average in the upper good to lower moderate range. A cold front producing more clouds and showers on Monday will push ozone back into the good range. A cooler and drier air mass will bring good air quality overall for the middle of next week.---McAuliffe
