Forecast Discussion: Tuesday, March 3: A cold front approaching the Buckeye State from the west will generate moderate southerly winds, bringing regional pollutants into the Columbus area. Furthermore, high relative humidity associated with rain and snow showers will support particle production. Therefore, AQI levels will be Moderate. Wednesday, March 4: The cold front will impact Ohio and depart to the east, enhancing atmospheric mixing and generating moderate northwesterly winds. These weather conditions will effectively disperse pollutants, resulting in Good AQI levels. Thursday, moderate northwesterly winds will persist in Columbus, dispersing pollutants and keeping AQI levels Good. Friday through Sunday, surface high pressure to the south of the Buckeye State will cause light to moderate southwesterly winds to develop in central Ohio, transporting regional pollutants and moisture into the area. These conditions, combined with pollutant carryover from day to day, will lead to Moderate AQI levels on all three days.
