Forecast Discussion: Friday, August 29: High pressure over the northeastern U.S. will generate light to moderate southeasterly winds in Columbus, transporting regional pollutants and moisture into the area. These conditions will enhance particle formation. In addition, mostly sunny skies and temperatures in the mid-80s will increase ozone formation. As a result, AQI levels will be Moderate. Saturday, August 30: A surface low-pressure system moving through the Upper Midwest will produce light to moderate southwesterly winds in central Ohio, transporting additional pollutants and moisture into the region. In addition, mostly sunny skies and temperatures near 90F will enhance ozone formation. Therefore, AQI levels will remain Moderate. Sunday, as the low-pressure system moves through the Great Lakes region, moderate southwesterly winds will disperse pollutants, and mostly cloudy skies with scattered thunderstorms will reduce ozone formation, lowering AQI levels to Good. Monday, moderate southerly winds ahead of a second low-pressure system will continue to disperse pollutants in central Ohio. Furthermore, mostly cloudy skies will continue to suppress ozone formation, keeping AQI levels Good. Tuesday, a front will move through the Buckeye State, increasing vertical mixing in the atmosphere and helping to disperse pollutants. In addition, cloudy skies and widespread rain showers will continue to inhibit ozone production. As a result, AQI levels will remain Good. Wednesday, mostly cloudy skies will limit ozone formation in central Ohio, and pollutant carryover from the previous day will be low. As a result, AQI levels will be Good.
