Forecast Discussion: Sunshine and a few clouds with a very warm Tuesday afternoon to start off September. While ozone concentrations are rising, they will not get above the lower moderate range. Sunny to partly cloudy Wednesday with another warm afternoon. Light winds and the sun will allow ozone production to go slightly higher, but still in the lower moderate range. As a cool front approaches from the north and west on Thursday, there will be an afternoon and evening thunderstorm. This will act to lower ozone to the lower moderate range. Further reductions in ozone are likely by Friday with more clouds, a little cooler air, and a shower or two.---McAuliffe
