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.

Forecast Discussion: Wednesday, June 20: Rain showers, thunderstorms, and mostly cloudy skies will limit ozone formation in the Columbus region, and light to moderate westerly winds will aid pollutant dispersion. Therefore, AQI levels will be Good. Thursday, June 21: Mostly cloudy skies will continue to limit ozone formation. Furthermore, easterly winds will bring a clean air mass into central Ohio, keeping AQI levels Good. Friday and Saturday, as a low pressure system moves through the Great Lakes region, mostly cloudy skies and thunderstorms will reduce ozone production, and moderate southerly winds will shift to westerly, keeping pollutants well dispersed. As a result, AQI levels will be Good on both days. Sunday, moderate southwesterly winds will keep the lower levels of the atmosphere well mixed, and mostly cloudy skies will inhibit ozone formation. As a result, AQI levels will remain Good. Monday, north-northeasterly winds will transport clean air into central Ohio, yielding Good AQI levels.
