Forecast Discussion: Wednesday, April 16: Surface high pressure moving across Ohio will generate light to moderate southeasterly winds in central Ohio, gradually transporting pollutants into the Columbus region. However, low pollutant carryover from Tuesday will lead to Good AQI levels. Thursday, April 17: A low-pressure system moving into the Midwest will produce moderate southerly winds in central Ohio, transporting regional pollutants into the Columbus area. Therefore, despite cool temperatures limiting ozone formation, AQI levels will be Moderate. Friday, continued moderate southerly winds will transport additional pollutants into central Ohio, keeping AQI levels Moderate. Saturday, a 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 and Monday, southerly winds ahead of another approaching low-pressure system will gradually transport regional pollutants into Columbus, enhancing particle production. Therefore, AQI levels will be Moderate on both days.
