Synopsis and Discussion

Pockets of lower Code Yellow ozone concentrations are being observed today while fine particle readings are lower in the Code Green range. Bermuda high pressure will drift westward over the Carolinas this weekend as a strong ridge builds over the eastern US. Temperatures will be on the increase, especially early next week, when highs could push 100 degrees. With plenty of sunshine, light winds, and a general sinking motion, significant degradation of the air mass is expected. AQI readings are expected to increase day on day, with ozone reaching the mid Code Yellow range on Sunday and upper Code Yellow range on Monday. Fine particle concentrations will increase as well, reaching Moderate levels on Sunday and Monday. The hot and sunny weather looks to continue through the workweek and with no change of air mass, multiple days of elevated AQI readings are certainly possible so stay tuned to the forecast!
