Forecast Discussion: Saturday, December 20: Surface high pressure over Ohio will produce light and variable winds in the Columbus area, limiting pollutant dispersion and yielding low-Moderate AQI levels. Sunday, December 21: Light southerly winds will develop in central Ohio as surface high pressure moves to the east, slowly transporting regional moisture and pollutants into the area. These conditions will support particle production, keeping AQI levels low-Moderate. Monday and Tuesday, a low-pressure system will approach from the west, generating moderate southeasterly winds in the Columbus area. These winds will bring additional pollutants and moisture into the region, aiding particle formation and yielding Moderate AQI levels on both days. Wednesday and Thursday, the low-pressure system will move through Ohio, 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.
