Monday, December 2: As surface high pressure approaches the Buckeye State, westerly winds will weaken, reducing pollutant dispersion. However, low regional pollutant carryover will lead to high-Good AQI levels. Tuesday, December 3: Surface high pressure south of Ohio will generate periods of light westerly winds, limiting dispersion throughout the day. Furthermore, a temperature inversion during the morning hours will trap pollutants near the ground, yielding low-Moderate AQI levels. Wednesday, southwesterly winds will strengthen as a cold front moves across central Ohio, enhancing mixing, dispersing pollutants, and lowering AQI levels to Good. Thursday, moderate and gusty west-northwesterly winds behind the departing cold front will keep pollutants well dispersed, resulting in continued Good AQI levels. Friday, winds will weaken and shift to westerly to southwesterly, transporting regional pollutants into the Columbus area. However, low pollutant carryover from the previous days will keep AQI levels Good. Saturday, periods of light southwesterly winds will transport moisture and additional pollutants into the Columbus region, increasing particle levels. However, mixing will be enhanced as the next cold front traverses the Buckeye State. Thus, AQI levels will be high-Good.
