Forecast Discussion: Saturday, April 18: Surface high pressure building over northern Ohio has caused winds to diminish in the Columbus area, reducing pollutant dispersion. Furthermore, mostly sunny skies and warm temperatures will increase ozone formation, leading to mid-Moderate AQI levels. Sunday, April 12: As a strong cold front approaches the Buckeye State from the west, breezy southeasterly winds ahead of the front will bring regional pollutants and moisture into central Ohio, aiding particle production. Therefore, despite mostly cloudy skies inhibiting ozone formation, AQI levels will be low-Moderate. Monday through Thursday, moderate to strong westerly winds will persist behind the departing cold front, effectively dispersing pollutants in the Columbus region. Furthermore, partly to mostly cloudy skies and cooler temperatures will limit ozone formation. These conditions, combined with low pollutant carryover from day to day, will yield Good AQI levels on all four days.
