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, October 23: As a cold front approaches central Ohio, moderate southerly winds and widespread rain showers will enhance atmospheric mixing. These conditions will effectively disperse pollutants, leading to Good AQI levels. Tuesday. October 24: Moderate southwesterly winds behind the departing cold front will keep pollutants well dispersed in the Columbus region, yielding continued Good AQI levels. Wednesday, mostly cloudy skies and rain showers will limit ozone formation, and light to moderate westerly winds will bring a cool, clean air mass into the Columbus area, keeping AQI levels Good. Thursday, as a low pressure system deepens to the northwest of central Ohio, moderate southwesterly winds will aid mixing and pollutant dispersion, resulting in Good AQI levels. Friday, winds will shift to westerly as a weak cold front moves through the Columbus region, dispersing pollutants and leading to Good AQI levels. Saturday, light northwesterly winds will gradually transport clean air into central Ohio, resulting in Good AQI levels.
