Forecast Discussion: Thanksgiving Day, November 27: Light to moderate westerly winds will bring pollutants into the Columbus region, and moisture associated with light snow will aid particle formation. As a result, AQI levels will be low-Moderate. Friday, November 28: Light to moderate west-southwesterly winds will continue to bring pollutants into the Columbus region. Therefore, despite lower humidity levels reducing particle formation, AQI levels will remain low-Moderate. Saturday and Sunday, as a cold front approaches central Ohio from the northwest, moderate south-southwesterly winds will bring pollutants and moisture into the region, increasing particle production and resulting in low-Moderate AQI levels on both days. Monday, moderate northwesterly winds behind the departing cold front will effectively disperse pollutants, lowering AQI levels to Good. Tuesday, winds shifting to east-northeasterly will keep pollutants well dispersed in central Ohio, keeping AQI levels Good.
