Forecast Discussion: Abundant sunshine and a rather dry atmosphere is allowing ozone concentrations to increase to YELLOW in the Upstate. Other zones will likely remain in the uppermost portion of the green category, but there's still opportunity for a couple of isolated areas between I-20 and I-85 to finish the day with a yellow reading. Sunday will feature another spectacular day weather-wise. Low temperatures will likely fall in the 50s with 80s in the afternoon statewide under another day with abundant sunshine. There has been an uptick Saturday in the amount of available precursors, allowing observations to be clustered around the green/yellow threshold. However, an increase in southeasterly flow on the southern flank of high pressure over the Mid-Atlantic should allow an increase in the maritime influence over the Palmetto State on Sunday. Although abundant sun will do all it can to generate ozone on Sunday, the fetch from the Atlantic Ocean and the lack of local emissions should limit ozone concentrations to perhaps an isolated YELLOW observation in the Upstate with all other zones remaining in the upper GREEN category.
