Forecast Discussion: Thursday, March 26: As a cold front moves through Ohio and departs to the southeast, moderate north-northwesterly winds behind it will effectively disperse pollutants in the Columbus region, leading to Good AQI levels. Friday, March 27: Moderate northwesterly winds will continue to disperse pollutants and bring clean air into central Ohio, keeping AQI levels Good. Saturday, as surface high pressure builds over the Midwest, moderate northwesterly winds will continue to disperse pollutants in the Columbus region, yielding Good AQI levels. Sunday, moderate to strong southwesterly winds ahead of an approaching cold front will transport some pollutants into central Ohio. However, these winds will also disperse pollutants and keep the lower levels of the atmosphere well mixed. Therefore, AQI levels will be Good. Monday, moderate westerly winds behind the departing front will keep pollutants well dispersed in the Columbus region, leading to Good AQI levels. Tuesday, as a low-pressure system quickly moves across the Great Lakes, southwesterly winds will shift to northwesterly in central Ohio, bringing clean air into the region and keeping AQI levels Good.
