The highest AQ index in South Carolina (as of 9:00 EDT) is currently the Florence and Darlington area. Particle Pollution (PM2.5) is measuring at 53 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Greenville-Spartanburg area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
We should see all zones finish at CODE GREEN for ground-level ozone this Friday afternoon. A cold front should move into South Carolina early Saturday morning and stall near the Upstate. Shower and thunderstorm chances should increase ahead and near the frontal system, as the southerly flow should bring more moisture content into the state, with lower chances elsewhere. Behind the front, there could be some local pluming issues that could elevate ozone levels in the Upstate, so a CODE YELLOW has been issued for this forecast zone. However, all other zones should see better air quality with the cloudiness and convection, and they should be at CODE GREEN for Saturday.
