Forecast Discussion: Tuesday, February 9: As a low-pressure system departs to the east, moderate westerly winds will aid pollutant dispersion in central Ohio. In addition, an upper-level trough of low pressure over the region will enhance atmospheric mixing. These conditions will lead to Good AQI levels. Wednesday, February 10: Continued westerly winds will effectively disperse pollutants and keep AQI levels Good. Thursday, moderate northwesterly winds will keep the lower levels of the atmosphere well mixed in the Columbus area. As a result, AQI levels will remain Good. Friday, light southwesterly winds will transport regional pollutants and moisture into central Ohio, enhancing particle formation. However, pollutant carryover from previous days will be low. Therefore, AQI levels will remain Good. Saturday, as a surface high pressure strengthens over the central U.S., moderate northerly winds will aid pollutant dispersion in the Columbus region, resulting in Good AQI levels. Sunday, the surface high pressure system will move over central Ohio, leading to light and variable winds and inhibiting pollutant dispersion. As a result, AQI levels will be low-Moderate.
