Forecast Discussion: Other than an isolated monitor or two near the most urban areas possibly peaking into the YELLOW category, most areas of the state will likely remain CODE GREEN under a general clean airmass. High pressure remains large and in charge along the Central Gulf Coast. The eastern flank of the ridge will begin to break down across the Carolinas late in the day on Friday. This will be followed by a backdoor front on Saturday. Temperatures will probably be the hottest of the season on Friday with some areas reaching or slightly exceeding 100. Although an isolated yellow can not be ruled out if winds are just slightly lighter than expected, a clean upstream and northwesterly downslope flow will keep ozone concentrations primarily on the CODE GREEN side.
