The highest AQ index in Ohio (as of 13:00 EST) is currently the Toledo area. Particle Pollution (PM2.5) is measuring at 79 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Columbus area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Tuesday, January 6: Southwesterly winds ahead of an approaching cold front will bring moisture and pollutants into the Columbus region. Additionally, regional pollutant carryover from the previous day will contribute to particle concentrations, leading to low-Moderate AQI levels. Wednesday, January 7: Lighter westerly to west-northwesterly winds will reduce pollutant dispersion as a surface ridge of high pressure passes over Ohio. Furthermore, these winds will gradually carry additional pollutants into the Columbus region, resulting in mid-Moderate AQI levels. Thursday, as a warm front traverses the Buckeye State, light southerly to southeasterly winds will transport pollutants into the Columbus region. Therefore, AQI levels will be low-Moderate. Friday and Saturday, as the next cold front moves across Ohio, mixing will increase. Furthermore, periods of moderate winds and rain showers will aid dispersion, yielding high-Good AQI levels on both days. Sunday, moderate and gusty westerly to west-southwesterly winds behind the departing front will transport cleaner, colder air into central Ohio, resulting in Good AQI levels.
