Forecast Discussion: Tuesday, January 27: Early morning fog and mist have enhanced particle formation in central Ohio. Therefore, despite light to moderate northwesterly winds helping to disperse pollutants and bring clean, cold air into central Ohio, AQI levels will be low-Moderate. Wednesday, January 28: As surface high pressure moves over the Buckeye State, light and variable winds will limit pollutant dispersion in the Columbus area, leading to low-Moderate AQI levels. Thursday, a surface low-pressure system moving through central Ohio will produce moderate southerly winds through the morning hours, bringing pollutants and moisture into the region. Therefore, despite northwesterly winds dispersing some pollutants in the evening, AQI levels will remain low-Moderate. Friday, moderate northwesterly winds behind the departing low-pressure system will effectively disperse pollutants in the Columbus region, leading to Good AQI levels. Saturday and Sunday, light southwesterly winds ahead of another approaching low-pressure system will gradually transport pollutants and moisture into central Ohio, enhancing particle formation. As a result, AQI levels will be low-Moderate on both days.
