Synopsis and Discussion

Air quality levels continue to remain well within the Code GREEN range today as the Triad remains under a conveyor belt of a vertically deep plume of moisture riding along the western periphery of an offshore high pressure ridge. This has triggered several rounds of showers and isolated storms through the day, and this setup is expected to continue through Thursday. Some breaks in the cloud deck could lead to brief increases in ozone, but the increase in solar radiation will quickly lead to destabilization of the atmosphere and lead to more convective showers/storms each day and keep ozone and particle pollution levels Code GREEN. Upper level ridging will begin to setup over the southeastern United States by the end of the week and eventually lead to a drier and more stable air mass. However, low-level moisture will likely remain high to limit ozone production and keep pollution AQI in the upper Code GREEN range on Friday. (Payne)
