Forecast Discussion: Saturday, February 6: Light southwesterly winds will gradually transport regional pollutants and moisture into the Columbus region, increasing particle production. These conditions will yield low-Moderate AQI levels. Sunday, February 7: As a low-pressure system slowly moves toward Ohio, light to moderate southerly winds will bring additional pollutants into central Ohio, leading to Moderate AQI levels. Monday, light to moderate southerly winds shifting to westerly in the afternoon will aid pollutant dispersion. Furthermore, an upper-level trough of low pressure over Ohio will enhance vertical mixing in the atmosphere. Therefore, despite increased humidity enhancing particle concentrations, AQI levels will lower to Good. Tuesday through Thursday, moderate westerly winds behind the departing low-pressure system will keep the lower levels of the atmosphere well mixed, yielding Good AQI levels on all three days.
