Forecast Discussion: Wednesday, March 4: A 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, March 5: Moderate northwesterly winds will persist in Columbus, effectively dispersing pollutants and keeping AQI levels Good. Friday and Saturday, 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 and enhancing particle production. These conditions, combined with pollutant carryover from day to day, will lead to Moderate AQI levels on both days. Sunday, a weak low-pressure system moving through the Great Lakes region will enhance mixing in the atmosphere and shift winds to westerly in the afternoon, helping to disperse pollutants. However, southwesterly winds throughout the morning will transport regional pollutants into the Columbus area, and pollutant carryover from the previous days will keep AQI levels low-Moderate. Monday, surface high pressure strengthening over the eastern U.S. will generate southwesterly winds in Columbus, continuing to transport regional pollutants into the area and keeping AQI levels low-Moderate.
