Forecast Discussion: Thursday, March 5: Moderate northerly winds will effectively disperse pollutants in Columbus, yielding Good AQI levels. Friday, March 6: 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 will lead to low-Moderate AQI levels. Saturday, southwesterly winds will persist ahead of an approaching low-pressure system, continuing to transport pollutants and moisture into the region. Therefore, AQI levels will be low-Moderate. 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, pollutant carryover from previous days will keep AQI levels low-Moderate. Monday and Tuesday, 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 on both days.
