Another day of record high temperatures and dry conditions has led to ozone levels to rise into the upper Code YELLOW range this afternoon. Low-level winds are expected to be a bit stronger and more westerly this afternoon and into the evening, which should keep ozone levels from reaching air quality alert status. An upper-level disturbance riding along the northern periphery of the ridge will pass through overnight, causing low-level winds to become more west to west-northwesterly through the day tomorrow. Temperatures are expected to be slightly lower, though downsloping winds off the Appalachians should keep high temperatures well above normal and keep ozone levels in the low to middle Code YELLOW range. Winds shift back to southwesterly on Saturday as the Triad sees another day of record high temperatures. An approaching cold front will intensify wind speeds through the afternoon, providing enough low-level dispersion to keep ozone levels in the upper Code YELLOW range. The cold front passes through the Triad early Sunday, bringing some much needed rain and temperature relief to the state. With that said, cloudy skies during the day on Sunday should keep air quality levels Code GREEN. Particle pollution is expected to remain a secondary pollutant, remaining low Code YELLOW through Saturday before dropping to Code GREEN on Sunday. (Payne) *** Due to increased wildfire risk and severe drought across most of the state, the N.C. Forest Service has issued a statewide ban on all open burning and has canceled all burning permits statewide. ***
