Forecast Discussion: Friday, April 17: Light northwesterly winds behind a departing cold front will disperse some pollutants in central Ohio. However, pollutant carryover from the overnight and early morning hours will result in low-Moderate AQI levels. Saturday, April 18: Surface high pressure building over northern Ohio will produce generally light winds in the Columbus area, limiting pollutant dispersion. Furthermore, mostly sunny skies and warm afternoon temperatures will increase ozone formation, leading to low-Moderate AQI levels. Sunday, as a strong cold front approaches the Buckeye State from the west, breezy southeasterly winds will bring regional pollutants and moisture into central Ohio, increasing particle production and leading to Moderate AQI levels. Monday through Wednesday, the cold front will move through Ohio and depart to the east, enhancing vertical mixing in the atmosphere and producing moderate to strong westerly winds. These weather conditions will effectively disperse pollutants in the Columbus region, yielding Good AQI levels on all three days.
