Forecast Discussion: A large area of high pressure in the Midwest is bringing the area dry and clean conditions with plenty of sunshine this Friday afternoon. Ozone concentrations remain well down into the good range. Periods of clouds and sunshine Saturday with only widely scattered late afternoon thundershowers. Ozone will again be limited to the good range. Warmer and more humid air late in the weekend into Monday will cause ozone to rise once more, and these levels might go moderate in parts of the area, depending on the timing of any thunderstorms Monday. Cooler and drier air then moves in by the middle of next week with improved air quality.---McAuliffe
