Synopsis and Discussion
After yesterday's high ozone concentrations, air quality levels have steadily risen into the lower Code YELLOW range this afternoon under a hot and humid air mass that has rotated in from the north along a strong upper-level ridge to the west. Scattered showers and thunderstorms are expected to be more numerous this afternoon, likely keeping air quality levels from rising further out of the low Code YELLOW range. A cold front passes through the Triad this evening and will allow for mostly cloudy skies and cooler temperatures for Saturday. We may see a bit more sun in the afternoon tomorrow, which may lead to air quality levels approaching the high Code GREEN to low Code YELLOW threshold. Particle pollution and ozone will likely be the primary driver for Code YELLOW AQI Sunday as temperatures begin to increase once again as skies remain mostly sunny ahead of another cold front approaching from the north. Chances of rain increase on Monday as the cold front nears the Triad, with showers and thunderstorms likely in the afternoon. For now, Code YELLOW AQI is expected for Monday as particle pollution will likely remain elevated ahead of the front. Increased cloud cover should keep ozone levels Code GREEN throughout the day on Monday, and post frontal particle pollution should also fall to Code GREEN by the evening. (Payne)
