The highest AQ index in Ohio (as of 9:00 EST) is currently the Columbus area. Particle Pollution (PM2.5) is measuring at 55 (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.
Saturday, December 13: A cold front will traverse the Buckeye State, generating moderate westerly to northwesterly winds. Although these winds will aid dispersion, they will also carry regional pollutants into central Ohio, keeping AQI levels low-Moderate. Sunday, December 14: As strong surface high pressure builds to the west, periods of moderate and gusty west-northwesterly winds will disperse pollutants and carry a clean, cold air mass into the Columbus region. As a result, AQI levels will be Good. Monday and Tuesday, moderate and gusty south-southwesterly winds will develop as the surface high passes south of the state, enhancing mixing and dispersion. However, these winds will gradually transport regional pollutants and moisture into central Ohio, increasing particle production. Therefore, AQI levels will be high-Good on Monday and low-Moderate on Tuesday. Wednesday, as a weak cold front moves through the Columbus region, moderate west-southwesterly winds will keep pollutants well dispersed before noon. However, winds will diminish in the afternoon as high pressure moves into Ohio, reducing dispersion and yielding low-Moderate AQI levels. Thursday, a strong cold front will impact the Columbus region, enhancing mixing and producing moderate to strong southerly winds. These weather conditions will effectively disperse pollutants, lowering AQI levels to Good.
