Triad Air Quality

Triad Forecast

Synopsis and Discussion

Surface high pressure continues to keep the Triad under sunny skies, light winds and lower dewpoints, which has provided a favorable environment for ozone production as AQI has reached the middle Code YELLOW range. More of the same is expected tomorrow, though a slight wind shift from the south will likely bring higher ozone concentrations tomorrow and elevate air quality levels into the middle to upper Code YELLOW range. Surface high pressure begins to break down on Friday as the upper-level ridge retrogrades to the west and allows for an upper-level disturbance to move into the region Friday afternoon. For now, low Code YELLOW AQI is expected for ozone as skies should remain precipitation free through noon, but an increase in storm coverage in the afternoon and evening may drop air quality levels further. Increased cloud cover on Saturday resulting from high pressure nudging in from the north should keep air quality levels Code GREEN. Particle pollution will likely remain largely a secondary pollutant to ozone through Friday, eventually dropping to Code GREEN by Saturday. (Payne)
