Synopsis and Discussion

A weakening cold air wedge has mostly held intact over the Triad today, keeping conditions cloudier and cooler to limit ozone concentrations from rising out of the middle Code GREEN range. Particle pollution levels started off in the Code GREEN range this morning but has gradually increased through the early afternoon and will likely reach Code YELLOW once the sun begins to peek through the cloud deck later this afternoon. Offshore Bermuda high pressure will dominate the weather pattern through tomorrow and the rest of the week, ushering in above average temperatures through Friday. Dewpoints are also expected to remain elevated, providing favorable weather for early spring agricultural burning for much of the southeastern United States. With that said, particle pollution is likely to remain elevated through the end of the week, with air quality levels hovering around the low to middle Code YELLOW range. Ozone will likely remain a secondary pollutant, but ozone AQI will likely reach Code YELLOW by Thursday/Friday as temperatures reach near record highs. (Payne)
