Forecast Discussion: Sunday, November 23: Moderate southeasterly winds ahead of an approaching cold front will bring regional pollutants and moisture into Columbus, enhancing particle production. As a result, AQI levels will be low-Moderate. Monday, November 24: A cold front will move through central Ohio, enhancing atmospheric mixing and shifting winds to southwesterly. These weather conditions will disperse pollutants, lowering AQI levels to Good. Tuesday, moderate and occasionally gusty westerly winds will persist behind the departing cold front, continuing to disperse pollutants and transport clean, dry air into central Ohio. As a result, AQI levels will remain Good. Wednesday, a weak low-pressure system will move through Ohio, enhancing atmospheric mixing and dispersing pollutants, keeping AQI levels Good. Thanksgiving, moderate northwesterly winds behind the departing low-pressure system will transport a clean, dry air mass into Columbus. Therefore, AQI levels will remain Good. Friday, an approaching low-pressure system will generate moderate southerly winds in central Ohio, transporting regional pollutants and moisture into the area, enhancing particle production and yielding low-Moderate AQI levels.
