Forecast Discussion: Monday, October 20: A weak low-pressure system moving through the Buckeye State will produce light to moderate southwesterly winds, transporting some regional pollutants into the Columbus region. However, low pollutant carryover from the weekend will lead to Good AQI levels. Tuesday, October 21: Moderate northwesterly winds behind the departing low-pressure system will disperse pollutants and transport cleaner air into central Ohio, keeping AQI levels Good. Wednesday and Thursday, as the low-pressure system moves over the Northeast and high pressure builds over the western Great Lakes, light to moderate northwesterly winds will persist in Columbus region, keeping pollutants well dispersed. Therefore, AQI levels will be Good on both days. Friday and Saturday, as surface high pressure moves over the Ohio River Valley, light westerly winds will reduce pollutant dispersion in central Ohio. However, a clean, dry air mass over the region will lead to Good AQI levels on both days.
