Forecast Discussion: Thursday, October 30: As surface high pressure moves over Ohio, light winds will reduce pollutant dispersion in the Columbus region. However, a dry air mass over the area will inhibit particle formation, leading to Good AQI levels. Friday, October 31: Light to moderate southerly winds ahead of an approaching low-pressure system will transport regional pollutants and moisture into central Ohio, enhancing particle formation. As a result, AQI levels will be low-Moderate. Saturday, as the low-pressure system moves across the Great Lakes and departs to the east, gusty north-northwesterly winds will develop in central Ohio, effectively dispersing pollutants and lowering AQI levels to Good. Sunday, light to moderate westerly winds will disperse pollutants in the Columbus region, keeping AQI levels Good. Monday and Tuesday, light to moderate southwesterly winds ahead of an approaching cold front will bring regional pollutants into the Columbus region. Therefore, AQI levels will be low-Moderate on both days.
