Synopsis and Discussion

Pockets of lower Code Yellow particle pollution are being observed today while ozone readings are much lower in the Code Green range. A backdoor cold front will pass through the Triad, offering a brief reprieve from the recent hot and very humid weather. AQI readings are expected to hover in the upper Code Green range tomorrow behind the front. Some diffuse smoke from Canadian wildfires is expected to drift over our area on Wednesday, likely enough to move the needle into the lower Code Yellow range for particle pollution. AQI readings will continue to hover near the Code Green/Yellow threshold into Thursday. (Perrotte)
