As of Monday mid-afternoon, the Upstate is trending Code Yellow for ground-level ozone concentration while the remaining forecast zones are trending Code Green for the rest of the day. The upper-level trough currently over South Carolina will weaken as the surface high pressure builds, resulting in warmer conditions while maintaining a dry air mass. Abundant sunshine is probable in addition to a stable atmosphere. Temperatures are forecast to rise to slightly above normal levels with highs in the 80s and lows in the low to mid-60s. Winds are expected to either be calm or light and variable statewide, which would allow ozone pollutants to pool in their originating location. Considering how dry and stagnant the air mass would be, the lack of dispersion has the potential to be the most crucial factor toward significant ozone production. Therefore, the ozone forecast for Tuesday projects all forecast zones to peak at CODE YELLOW.
