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.

Forecast Discussion: Thursday, February 23: Light to moderate southerly winds will transport regional pollutants into the Columbus area. Therefore, AQI levels will be low-Moderate. Friday, February 24: Southwesterly winds will persist, bringing additional pollutants into central Ohio. However, winds will strengthen throughout the day, dispersing pollutants and leading to high-Good AQI levels. Saturday, a low pressure system will impact Ohio, enhancing mixing in the atmosphere and generating moderate to strong westerly winds at the surface. These conditions will effectively disperse pollutants, keeping AQI levels Good. Sunday, westerly winds through the morning hours will transport a clean air mass into the region, keeping AQI levels Good. Monday, light southeasterly winds will reduce pollutant dispersion in central Ohio, yielding low-Moderate AQI levels. Tuesday, as a weak cold front departs to the east, light westerly winds will gradually bring cleaner air into the Columbus region, lowering AQI levels to Good.
