Synopsis and Discussion

Ozone concentrations have risen into the lower Code Yellow range across parts of the Triad while particle pollution remains lower in the Upper Code Green range. Code Yellow ozone levels are expected to persist through the rest of the workweek before increasing storm chances shut down ozone production for the first half of the weekend. While there is a chance of storms on Friday afternoon, there may be enough hours in the Code Yellow range around and just after lunchtime for averages to net out in the lower Code Yellow range. Particle pollution averages are expected to net out in the upper Code Green range for the balance of the forecast period but there may be some occasional hours with readings in the lower Code Yellow range.
