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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Monday, August 20: Moderate south-southeasterly winds ahead of an approaching low pressure system will increase mixing in the atmosphere, aiding pollutant dispersion. In addition, mostly cloudy skies will reduce ozone formation. Therefore, AQI levels will be Good. Tuesday, August 21: A low pressure system will impact the Columbus region, increasing vertical mixing in the atmosphere and generating moderate to strong winds at the surface. In addition, mostly cloudy skies will reduce ozone formation. As a result, AQI levels will be Good. Wednesday, moderate west-northwesterly winds behind the departing system will aid pollutant dispersion. However, these winds will also transport smoke from wildfires from the western U.S. and Canada into the Columbus region, increasing particle levels. Therefore, AQI levels will be low-Moderate. Thursday, lighter winds will reduce pollutant dispersion, and sunny, warm conditions will enhance ozone formation. As a result, AQI levels will remain low-Moderate. Friday, south-southeasterly winds will strengthen throughout the day, increasing mixing in the low levels of the atmosphere. Therefore, despite sunny skies and temperatures in the low-80s enhancing ozone formation, AQI levels will be low-Moderate. Saturday, a front will impact the Columbus region, increasing vertical mixing and generating moderate to strong winds at the surface. These conditions will effectively disperse pollutants, yielding high-Good AQI levels.
