Forecast Discussion: Thursday, December 12 and Friday, December 13: Light southeasterly winds will reduce pollutant dispersion in central Ohio. In addition, cold morning temperatures will produce a strong inversion, trapping pollutants near the ground. These conditions will lead to low-Moderate AQI levels on both days. Saturday, morning fog and mist will enhance particle production in the Columbus area. However, another cold front will approach the Buckeye State, shifting winds to northwesterly and aiding pollutant dispersion. Therefore, AQI levels will be high-Good. Sunday, moderate and gusty winds behind the departing cold front will transport cleaner air into central Ohio, resulting in Good AQI levels. Monday, winds will shift to southeasterly as surface high pressure passes over Ohio. These winds will continue to aid dispersion, allowing AQI levels to remain Good. Tuesday, a low pressure will move through central Ohio and shift winds to westerly. These winds will gradually bring cleaner air into the state, keeping AQI levels Good. |
