Forecast Discussion: Tuesday, April 15: A cold front will move through the Buckeye State and depart to the east, enhancing vertical mixing in the atmosphere and shifting winds to northwesterly in the Columbus area. These weather conditions will effectively disperse pollutants and bring clean air into the region, resulting in Good AQI levels. Wednesday, April 16: Surface high pressure moving across Ohio will generate light southerly winds in central Ohio, gradually transporting pollutants into the Columbus region. However, low pollutant carryover from Tuesday will lead to Good AQI levels. Thursday and Friday, a low-pressure system moving into the Midwest will produce moderate southeasterly winds in central Ohio, transporting regional pollutants into the Columbus area. Therefore, despite cool temperatures limiting ozone formation, AQI levels will be Moderate on both days. Saturday, the low-pressure system will move eastward across Ohio, enhancing vertical mixing and shifting winds to northwesterly. These weather conditions will effectively disperse pollutants, resulting in Good AQI levels. Sunday, southerly winds ahead of an approaching low-pressure system will gradually transport regional pollutants into Columbus, yielding low-Moderate AQI levels.
