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: Sunday, April 30: Moderate southerly winds will transport regional pollutants into central Ohio. In addition, warm temperatures and partly sunny skies will enhance ozone formation. However, low pollutant carryover from previous days will lead to high-Good AQI levels. Monday, May 1: A cold front will move through Ohio, generating moderate and gusty southwesterly winds in the Columbus area. These winds will effectively disperse pollutants, yielding Good AQI levels. Tuesday, moderate southwesterly to westerly winds behind the departing cold front will keep pollutants well dispersed, leading to continued Good AQI levels. Wednesday, light westerly to northwesterly winds will gradually bring clean air into central Ohio, keeping AQI levels Good. Thursday and Friday, a low pressure system passing to the south will generate moderate northeasterly winds in the Columbus region, dispersing pollutants and leading to Good AQI levels on both days.
