Forecast Discussion: Wednesday, November 26: Light northerly winds will reduce pollutant dispersion in central Ohio, leading to low-Moderate AQI levels. Thanksgiving Day, November 27: A weak low-pressure system passing to the north of Ohio will generate moderate west-northwesterly winds in the Columbus region, dispersing pollutants and yielding Good AQI levels. Friday and Saturday, as a cold front approaches central Ohio from the northwest, light to moderate south-southwesterly winds will bring pollutants and moisture into the region, increasing particle production and resulting in Moderate AQI levels on both days. Sunday, as the cold front moves into Ohio, moderate to strong southwesterly winds will increase mixing and dispersion in the Columbus region. However, these winds will also bring pollutants and moisture into the area, supporting particle production and yielding low-Moderate AQI levels. Monday, moderate northwesterly winds behind the departing cold front will effectively disperse pollutants, lowering AQI levels to Good.
