Forecast Discussion: Saturday, March 25: Moderate southwesterly winds through the morning hours will bring regional pollutants into the Columbus area. However, these winds will be strong enough to keep the atmosphere well mixed. As a result, AQI levels will be high-Good. Sunday, March 26: As a low pressure system moves into Ohio, moderate and gusty southeasterly winds will develop, dispersing pollutants and keeping AQI levels Good. Monday, light to moderate southwesterly winds behind the departing low pressure system will transport clean air into central Ohio, leading to Good AQI levels. Tuesday, as another low pressure system moves through central Ohio, moderate northwesterly afternoon winds and scattered thunderstorms will keep the atmosphere well mixed, dispersing pollutants and yielding Good AQI levels. Wednesday and Thursday, as surface high pressure builds over the Great Lakes, light to moderate northeasterly winds will bring clean, dry air into the Columbus region, keeping AQI levels Good on both days.
