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: Monday, February 27: Light to moderate southerly winds will gradually bring pollutants into central Ohio. However, pollutant carryover from previous days will be low. Therefore, AQI levels will be Good. Tuesday, February 28: Southerly winds will strengthen slightly, aiding pollutant dispersion. However, these winds will also transport regional pollutants and moisture into central Ohio, enhancing particle formation and leading to low-Moderate AQI levels. Wednesday, a cold front will gradually pass through Ohio, enhancing atmospheric mixing and generating moderate southwesterly to westerly winds. These winds will aid pollutant dispersion at the surface, lowering AQI levels to Good. Thursday and Friday, moderate westerly to northwesterly winds behind the departing cold front will effectively disperse pollutants and bring a clean air mass into the Columbus area, keeping AQI levels Good on both days. Saturday, southwesterly winds will bring regional pollutants into central Ohio. However, low pollutant carryover from Friday will keep AQI levels Good.
