Forecast Discussion: Brisk west to northwest winds are keeping ozone concentrations down into the good range this Friday afternoon in spite of a good deal of sunshine. Periods of clouds and sunshine Saturday with only a pop up thundershower in parts of the area in the afternoon. Deep low level mixing will keep ozone levels down into the good range. A little warmer and more humid Sunday with perhaps a little higher ozone readings, but continued in the upper good range. Times of clouds and sunshine, warm, and humid Monday with a shower or thunderstorm. Ozone will remain in the upper good range. Good air quality is in store for the middle of next week as a cooler and drier air mass works it's way in.---McAuliffe
