Synopsis and Discussion

A smoky air mass remains in place and fine particle levels are Moderate today. Ozone is hovering in the upper Code Green range. A boundary will settle south of the Triad tomorrow, allowing some cleaner air to push southward and AQI readings are expected to decrease to the upper Code Green range as a result. As surface high pressure drifts eastward toward the coast, southwesterly low-level flow will allow some of the smoke that was pushed south and west to drift back over the area. AQI readings are expected to increase to the lower Code Yellow range once again. By Wednesday, the surface high will be offshore and drifting more southeastward, thereby allowing for more of an Atlantic influence on the air mass. Ozone and particle pollution levels are expected to decrease to the upper Code Green range. (Perrotte)
