Forecast Discussion: Friday, October 24: As surface high pressure moves over the Ohio River Valley, light southwesterly winds will reduce pollutant dispersion and gradually transport regional pollutants and moisture into the Columbus area. These conditions will aid particle production, resulting in low-Moderate AQI levels. Saturday, October 25: Light to moderate southwesterly winds associated with a passing cold front will bring additional pollutants into central Ohio, enhancing particle formation and keeping AQI levels low-Moderate. Sunday, light to moderate westerly winds behind the departing cold front will disperse pollutants and bring cleaner, drier air into the Columbus region, lowering AQI levels to Good. Monday and Tuesday, moderate southerly winds will develop as another cold front approaches from the west, bringing regional pollutants and moisture into central Ohio. These conditions will support particle production, resulting in Moderate AQI levels on both days. Wednesday, as the cold front departs to the southeast, moderate westerly winds behind it will disperse pollutants, yielding Good AQI levels.
