AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
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.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Ozone concentrations are once again being held down in the GREEN category across South Carolina on this Thursday afternoon. A front has shifted south into the state and is stalling across the Midlands. North of the front, in areas such as the Upstate and Catawba zones, the air mass is a tad dirtier, but clouds are keeping a lid on concentrations up there. South of the front, we're holding onto more of a clean, tropical-like air mass, and cloud build-ups and afternoon convection are further curtailing ozone readings. For Friday, the front fades off the map and the flow turns more southerly (and clean) for all zones. This will work with another day of ample moisture and PM convection to keep ozone levels at code GREEN state-wide.
