Forecast Discussion: Wednesday, December 17: Moderate westerly winds behind a departing low-pressure system will disperse pollutants and bring clean air into the Columbus region, resulting in Good AQI levels. Thursday, December 18: Light to moderate westerly winds will keep pollutants well dispersed in central Ohio, yielding continued Good AQI levels. Friday, as surface high pressure moves over the western Great Lakes, westerly winds will diminish in the Columbus area, reducing pollutant dispersion. However, a dry air mass over the region will limit particle formation, keeping AQI levels Good. Saturday, as high pressure shifts to the east, light to moderate northeasterly winds will develop in central Ohio, dispersing pollutants and keeping AQI levels Good. Sunday and Monday, a low-pressure system approaching from the west will generate moderate southerly winds in central Ohio, transporting pollutants into the region and leading to low-Moderate AQI levels on both days.
