Forecast Discussion: Sunday, December 21: Light southeasterly winds will develop as surface high pressure moves east of Ohio, limiting pollutant dispersion and slowly transporting regional moisture and pollutants into the Columbus area. These conditions will support particle production, yielding Moderate AQI levels. Monday, December 22: A low-pressure system approaching from the west will generate moderate southeasterly winds in central Ohio. These winds will bring additional pollutants and moisture into the region, aiding particle formation and resulting in Moderate AQI levels. Tuesday, moderate southeasterly winds ahead of the approaching low-pressure system will continue to transport moist, polluted air into the Columbus region, keeping AQI levels Moderate. Wednesday and Thursday, the low-pressure system will move through the Buckeye State, enhancing mixing in the lower levels of the atmosphere and producing breezy southwesterly winds in central Ohio. These weather conditions will effectively disperse pollutants, resulting in Good AQI levels on both days. Friday, moderate southwesterly winds ahead of an approaching cold front will help to disperse pollutants in the Columbus region, therefore, AQI levels will remain Good.
