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: Friday, November 17: Calm winds during the morning hours will inhibit pollutant dispersion. However, moderate south-southeasterly winds developing midday will aid mixing, and pollutant carryover from Thursday will be low. Therefore, AQI levels will be Good. Saturday, November 18: A cold front will move through Ohio in the evening, enhancing mixing in the atmosphere and generating moderate to strong winds at the surface. These conditions will effectively disperse pollutants, leading to Good AQI levels. Sunday through Tuesday, westerly to southwesterly winds behind the departing cold front will aid pollutant dispersion and bring a clean, cool air mass into the Columbus region. As a result, AQI levels will be Good on all three days. Wednesday, another cold front will move through central Ohio and keep the low levels of the atmosphere well mixed. Therefore, AQI levels will remain Good.
