The highest AQ index in South Carolina (as of 15:00 EDT) is currently the Greenville-Spartanburg area. Particle Pollution (PM2.5) is measuring at 54 (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 Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
As of Thursday afternoon, all forecast regions are trending towards a code Green finish. Overnight Thursday and into Friday, rain potentials associated with the approaching named storm could persist throughout the morning. Accompanied is an increase in daytime cloud coverages and a Westerly moderate breeze. A moisture-laden environment will inhibit any significant ozone production. The mostly maritime influence on the airmass entering the state bodes well for another day of clean air quality. Overall for Friday, all forecast regions are projected to peak in code Green to round out the week.
