Moderate
Forecast Discussion: Very warm and humid conditions continue across the area with showers and a thunderstorm developing as well this Wednesday afternoon. Ozone will thus be limited to the lower moderate range. A cold front then approaches later on Thursday, and brings a shower or thunderstorm once more. Therefore, ozone concentrations will not rise higher than the lower moderate zone. More cloudiness and an easterly flow on Friday will mean lower levels of ozone. Good air quality will continue into the early part of the holiday weekend.---McAuliffe
