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: Tuesday, February 21: An upper-level trough of low pressure will increase mixing in the atmosphere, and moderate southwesterly winds at the surface will disperse pollutants. As a result, AQI levels will be high-Good. Wednesday, February 22: Light southwesterly winds will reduce pollutant dispersion and transport regional pollutants into the Columbus area. Therefore, AQI levels will be low-Moderate. Thursday, southwesterly winds will persist in the Columbus region, transporting pollutants into central Ohio and keeping AQI levels low-Moderate. Friday, light southerly winds will continue to transport regional pollutants into central Ohio ahead of an approaching low pressure system. Therefore, despite stronger winds developing later in the day and helping to disperse pollutants, AQI levels will remain low-Moderate. Saturday, a low pressure system will impact Ohio, enhancing mixing in the atmosphere and generating moderate winds at the surface. These conditions will effectively disperse pollutants, lowering AQI levels to Good. Sunday, west-northwesterly winds behind the departing system will transport a cleaner air mass into the region, keeping AQI levels Good.
