AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.

Forecast Discussion: Hot and humid conditions continued across the forecast area Wednesday afternoon. Light northerly winds had pushed the Charlotte plume across the Catawba monitor, with a similar effect occurring at the Jackson monitor southeast of Augusta. Scattered showers and thunderstorms and backing flow should help to curb ozone production in these two zones, but not before they reach 8 hour ground level ozone concentrations in the yellow category. Somewhat cleaner air will enter the region behind a weak trough on Thursday. Light northwest flow behind the trough should yield another yellow category day in the Catawba zone, with the rest of the forecast area expected to see green category conditions.
