AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)

Forecast Discussion: Monday, January 23: As a low pressure system approaches and passes south of Ohio, north-northeasterly winds will strengthen in the Columbus region, transporting a cleaner air mass into the area and yielding Good AQI levels. Tuesday, January 24: As the low pressure system departs to the east, light to moderate west-northwesterly winds will aid pollutant dispersion in central Ohio. Therefore, despite these winds also bringing regional pollutants into the area, AQI levels will remain Good. Wednesday and Thursday, as another low pressure system approaches and passes over the Great Lakes, moderate southwesterly to westerly winds will effectively disperse pollutants in the Columbus area, leading to Good AQI levels on both days. Friday and Saturday, moderate westerly winds will keep the low levels of the atmosphere well mixed, keeping AQI levels Good on both days.
