We should see all zones finish at CODE GREEN for ground-level ozone this Friday afternoon. A weak cold front is forecast to move into the Palmetto State on Saturday and stall near the Midlands, stretching from the Pee Dee region down to Central Savannah River Area. A chance of showers and thunderstorms should occur for the eastern half of South Carolina, while the western half should see slightly drier and warmer conditions and veering winds that could bring ozone concentrations to higher levels. Thus, the Upstate zone is forecast to be at CODE YELLOW, while all other zones should remain at CODE GREEN for Saturday.
