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: Thursday, October 19: Moderate southwesterly winds will aid pollutant dispersion in central Ohio. Therefore, despite these winds also transporting regional pollutants into the area, AQI levels will be Good. Friday, October 20: An upper-level ridge of high pressure over Ohio will inhibit vertical mixing, and calm to light southwesterly winds near the surface will limit horizontal pollutant dispersion. Furthermore, warming temperatures will aid ozone formation. These conditions will result in Moderate AQI levels. Saturday and Sunday, light southerly to southwesterly winds will reduce pollutant dispersion and gradually transport regional pollutants into the Columbus area. In addition, mostly sunny skies and warm temperatures will aid ozone formation. Therefore, AQI levels will be low-Moderate on both days. Monday, a cold frontal passage will generate westerly winds in central Ohio, transporting clean, cool air into the region. Therefore, AQI levels will lower to Good. Tuesday, moderate northwesterly winds behind the departing cold front will transport a clean air mass into the Columbus area and keep AQI levels good.
