Forecast Discussion: Sunday, March 1: Moisture associated with fog and mist has enhanced particle production in the Columbus area. In addition, generally light southwesterly winds will limit pollutant dispersion. As a result, AQI levels will be low-Moderate. Monday, March 2: Moderate northwesterly winds behind the departing cold front will disperse pollutants and transport a cleaner air mass into central Ohio, yielding Good AQI levels. Tuesday, a low-pressure system approaching the Buckeye state from the west will produce moderate southerly winds, bringing some regional pollutants into the Columbus area. Furthermore, moisture associated with rain and snow showers will aid particle production. Therefore, AQI levels will be low-Moderate. Wednesday and Thursday, the low-pressure system will impact Ohio and depart to the east, enhancing atmospheric mixing and generating moderate northwesterly winds. These weather conditions will effectively disperse pollutants, resulting in Good AQI levels on both days. Friday, surface high pressure building south of the Buckeye State will cause light to moderate southwesterly winds to develop in central Ohio, transporting some regional pollutants into the area and yielding Moderate AQI levels.
