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: Wednesday, October 16: A cold front will pass through central Ohio, which will generate gusty westerly winds. These winds will bring a clean, cool air mass into the Columbus area. Additionally, clouds will inhibit ozone formation, resulting in Good AQI levels. Thursday, October 17: Mostly cloudy skies and temperatures in the mid-50s will limit ozone formation. Furthermore, moderate and gusty west-northwesterly winds will continue to disperse pollutants. Thus, AQI levels will remain Good. Friday and Saturday, increasing sunshine will aid ozone formation, while lighter winds will limit dispersion. However, low pollutant carryover from previous days will allow AQI levels to remain Good on both days. Sunday and Monday, increasing clouds and scattered showers will inhibit ozone production. Therefore, despite light southerly to southeasterly winds hindering pollutant dispersion, AQI levels will be Good on both days.
