Forecast Discussion: Monday, October 5: Surface high pressure over the Upper Midwest will produce light to moderate north to northeasterly winds in the Columbus region today, bringing clean air into the area and keeping AQI levels Good. Tuesday, October 6: Surface high pressure will build over central Ohio, leading to lighter winds and reducing pollutant dispersion. However, low pollutant carryover from previous days will keep AQI levels Good. Wednesday, despite light winds in the morning leading to increased pollutant levels, light to moderate northerly winds late in the day will disperse pollutants in the Columbus region, keeping AQI levels Good. Thursday, a cold front approaching the Buckeye State from the west will produce southerly winds, bringing some regional pollutants into the area. These conditions, along with pollutant carryover from Wednesday, will lead to low-Moderate AQI levels. Friday, continuing southerly winds will transport moisture and pollutants in the Columbus area, aiding particle formation and causing AQI levels to remain low-Moderate. Saturday, northerly winds will bring a clean, dry, and seasonably cool air mass into central Ohio, leading to Good AQI levels.
