Forecast Discussion: Wednesday, February 10: Moderate westerly winds behind a departing low-pressure system will keep the lower levels of the atmosphere well mixed. Therefore, despite high relative humidity associated with snow showers enhancing particle production, AQI levels will be Good. Thursday, February 11: Moderate northwesterly winds will continue to aid pollutant dispersion and bring clean air into the Columbus region. These conditions will keep AQI levels Good. Friday, a surface high-pressure system over Ohio will generate light southwesterly winds, transporting regional pollutants into the area and enhancing particle formation. However, pollutant carryover from previous days will be low. As a result, AQI levels will remain Good. Saturday, as surface high pressure strengthens over the central U.S., moderate northwesterly winds will effectively disperse pollutants in the Columbus region and lead to Good AQI levels. Sunday and Monday, the surface high-pressure system will move over the eastern U.S. and generate light southerly winds in central Ohio. These winds will transport regional pollutants and moisture into the Buckeye state, increasing particle production. Therefore, AQI levels will be Moderate on both days.
