For 8/14/2020
[ The forecast is updated daily by 3:30 pm EDT. ]
The trend is Green for most of the Palmetto State for ground level ozone concentrations of the mid-afternoon Thursday. The Central Savannah River area and the Upstate could possibly finish yellow if afternoon thunderstorms hold off in those locations long enough. Deep tropical moisture is likely to continue to be driven into the state thanks to the influence of a trough to the west and the flow around a Bermuda high offshore. A surface trough will be positioned across the northern third of the Palmetto State on Friday. This feature will likely enhance shower and thunderstorm development during peak heating Friday afternoon nullifying any late morning ozone production we see. The surge in moisture should also inhibit ground level ozone production before storms developing. As a result, code GREEN is expected statewide.
