Forecast Discussion: Thursday, November 20: Strong westerly winds behind a departing cold front will disperse pollutants and bring clean, dry air into central Ohio. These conditions will inhibit particle formation, resulting in Good AQI levels. Friday, November 21: As surface high pressure moves over southern Ohio, lighter winds will reduce pollutant dispersion in the Columbus region. However, low pollutant carryover from previous days will keep AQI levels Good. Saturday and Sunday, moderate southerly winds ahead of an approaching low-pressure system will bring pollutants into central Ohio, and moisture associated with rain showers will aid particle formation. As a result, AQI levels will be low-Moderate on both days. Monday, as the low-pressure system moves through the Great Lakes, winds shifting to west-southwesterly will disperse pollutants in the Columbus region. Therefore, AQI levels will be Good. Tuesday, moderate west-southwesterly winds will continue to disperse pollutants in central Ohio, yielding Good AQI levels.
