Forecast Discussion: Thursday, October 23: Light northwesterly winds will bring clean, dry air into central Ohio, limiting ozone and particle production and yielding Good AQI levels. Friday, October 24: As surface high pressure moves over the Ohio River Valley, light southwesterly winds will reduce pollutant dispersion and gradually transport some regional pollutants and moisture into central Ohio. These conditions will aid particle production, resulting in low-Moderate AQI levels. Saturday and Sunday, a low-pressure system moving across the northern Great Lakes will produce moderate westerly winds in the Columbus region, dispersing pollutants and leading to Good AQI levels on both days. Monday and Tuesday, moderate to strong southerly winds will develop as a low-pressure system approaches from the west, bringing regional pollutants and moisture into central Ohio. These conditions will support particle production, resulting in Moderate AQI levels on both days.
