Forecast Discussion: Sunday, January 25: A low-pressure system moving into the Ohio River Valley will enhance atmospheric mixing and disperse some pollutants. However, a moist air mass in place will enhance particle formation, resulting in low-Moderate AQI levels. Monday, January 26: Moderate northwesterly winds behind the departing low-pressure system will disperse pollutants and transport a cleaner, drier air mass into the Columbus region, lowering AQI levels to Good. Tuesday, light to moderate northwesterly winds will continue to disperse pollutants and bring clean, cold air into central Ohio. Therefore, AQI levels will remain Good. Wednesday, as surface high pressure moves over the Buckeye State, light northwesterly winds will shift to southerly. These winds will limit pollutant dispersion and gradually transport regional pollutants and moisture into the Columbus area, aiding particle production and increasing AQI levels to Moderate. Thursday, a surface low-pressure system will move through central Ohio, enhancing mixing and producing light to moderate southwesterly winds, shifting to northwesterly in the evening. While these weather conditions will disperse some pollutants, high relative humidity will increase particle production, keeping AQI levels Moderate. Friday, moderate northwesterly winds behind the departing low-pressure system will effectively disperse pollutants in Columbus, leading to Good AQI levels.
