Triad Air Quality

Triad Forecast

Synopsis and Discussion

Ozone levels have risen into the lower Code YELLOW range this afternoon as skies have remained sunny enough to allow for decent ozone production over the Triad. Cloud cover should increase later this afternoon and evening as a surface front currently south of the Triad lifts northward as a warm front, increasing the chances of showers and possible thunderstorms through the overnight hours into Wednesday morning. Skies should clear out through the morning as the storm system moves off to the east, downsloping westerly winds off the Appalachians should generate enough compressional warming and drying air to elevate ozone AQI to Code YELLOW. Thursday should be another dry day into the early afternoon, but another cold front moves in from the northwest and should keep ozone levels from rising out of the upper Code GREEN range. This cold front moving through the Triad late Thursday is a result of an upper low pressure system that is expected to sit over the eastern United States through the Memorial Day weekend, keeping temperatures below normal for this time of year. With that said, air quality levels should easily remain Code GREEN from late Thursday into the weekend. Also, particle pollution is expected to remain Code GREEN AQI through Friday. (Payne)
