As of Thursday mid-afternoon, all forecast zones are trending toward Code Green for ground-level ozone concentration for the rest of the day. The approaching backdoor cold front is expected to pass through South Carolina and then stall over the area on Friday. The high-pressure system behind it should bring mostly to partly sunny skies throughout much of the day, but there are still chances for afternoon showers and thunderstorms in the southern half of the state with the backdoor front still present. A slight cooldown for daytime temperatures is likely with highs in the low to mid-80s while the lows remain about the same at around the 60s. Precursor pollutants will be dispersed with a northeasterly to easterly breeze consistent across the state before shifting toward a southeasterly flow with varying speeds in the afternoon. While ozone production is expected to increase compared to the past several days, the variables do not support any significant buildup; therefore, the ozone forecast for Friday projects all forecast zones to peak at CODE GREEN.
