Forecast Discussion: Saturday, March 28: Surface high pressure over Lower Michigan will produce moderate northerly winds in the Columbus region, effectively dispersing pollutants and resulting in Good AQI levels. Sunday, March 29: Moderate southerly 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 remain Good. Monday, moderate west-northwesterly winds behind the departing cold 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 southern Great Lakes, southwesterly winds will shift to northwesterly in central Ohio, bringing clean air into the region and keeping AQI levels Good. Wednesday, as surface high pressure moves over the Northeast, moderate southeasterly winds will keep pollutants well dispersed in the Columbus region, leading to continued Good AQI levels. Thursday, as a cold front approaches from the west, moderate southwesterly winds ahead of it will bring pollutants into central Ohio. As a result, AQI levels will be low-Moderate.
