Forecast Discussion: Saturday, December 16, and Sunday, December 17: South-southwesterly winds will gradually transport regional pollutants and moisture into the Columbus area, enhancing particle formation. As a result, AQI levels will be Good on Saturday and low-Moderate on Sunday. Monday, light southwesterly winds will limit mixing and continue to bring regional pollutants and moisture into central Ohio. Therefore, AQI levels will remain low-Moderate. Tuesday, southwesterly winds will strengthen ahead of an approaching cold front, increasing mixing in the lower levels of the atmosphere and aiding pollutant dispersion. These conditions will lower AQI levels to high-Good. Wednesday, moderate north-northwesterly winds behind the departing front will transport a cleaner air mass into central Ohio, keeping AQI levels Good. Thursday, light to moderate easterly winds will aid pollutant dispersion, yielding continued Good AQI levels.
