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: Wednesday, January 17: Light westerly winds through the morning hours will reduce pollutant dispersion. Therefore, despite stronger afternoon winds aiding pollutant dispersion, AQI levels will be low-Moderate. Thursday, January 18: Moderate southwesterly winds will increase mixing in the low levels of the atmosphere, aiding pollutant dispersion. However, these winds will also transport regional pollutants into the area, keeping AQI levels low-Moderate. Friday and Saturday, moderate south-southwesterly winds will continue to increase mixing in the low levels of the atmosphere and aid pollutant dispersion in the Columbus area. As a result, AQI levels will be high-Good on both days. Sunday, lighter south-southwesterly winds will reduce pollutant dispersion in the Columbus region, keeping AQI levels high-Good. Monday, moderate south-southeasterly winds developing ahead of an approaching low pressure system will transport a cleaner air mass into central Ohio. As a result, AQI levels will be Good.
