Forecast Discussion: Monday, September 15: Light to moderate southwesterly winds ahead of an approaching cold front will gradually bring some pollutants into central Ohio. However, partly cloudy skies will limit ozone formation. These conditions, combined with low regional pollutant carryover from Sunday, will yield Good AQI levels. Tuesday, September 16: Light north-northwesterly winds behind the departing cold front will help to disperse pollutants and bring a cleaner air mass into the Columbus area, leading to Good AQI levels. Wednesday and Thursday, as surface high pressure moves over the northern Great Lakes, moderate northeasterly winds will keep pollutants well dispersed in central Ohio, resulting in Good AQI levels on both days. Friday, winds will shift to easterly as the surface high pressure moves over the Northeast, helping to disperse pollutants in the Columbus area. However, mostly sunny skies and temperatures in the mid-70s will aid ozone formation; therefore, AQI levels will be low-Moderate. Saturday, southeasterly winds ahead of an approaching cold front will transport some pollutants into central Ohio. In addition, sunny, warmer conditions will continue to increase ozone formation. As a result, AQI levels will remain Moderate.
