Forecast Discussion: Friday, July 31: A surface high pressure system to the west of Ohio will generate light to moderate westerly winds in the Columbus region, dispersing pollutants. Therefore, despite mostly sunny skies and warm temperatures supporting ozone formation, AQI levels will be Good. Saturday, August 1: A weak cold front moving through the Buckeye State will shift winds from southwesterly to westerly, dispersing pollutants. Therefore, AQI levels will remain Good. Sunday and Monday, as surface high pressure moves over Ohio, lighter southwesterly winds will reduce pollutant dispersion in central Ohio, and mostly sunny skies and warm temperatures will support ozone formation. As a result, AQI levels will be Moderate on both days. Tuesday, as a cold front passes through Ohio, moderate winds shifting from southwesterly to northwesterly will bring a cleaner air mass into the Columbus area. Furthermore, cloudy skies and thunderstorms will inhibit ozone production, resulting in Good AQI levels. Wednesday, continuing northerly winds will transport dry air into central Ohio, limiting particle formation. These winds, along with mostly cloudy skies and low pollutant carryover, will keep AQI levels Good.
