For 7/27/2024
[ The forecast is updated daily by 3:30 pm EDT. ]
We should see all zones finish at CODE GREEN for ground-level ozone this Friday afternoon. A frontal system should drop into South Carolina from the north on Saturday, drying out the atmosphere. There is still a chance for convection in the western Upstate, along the Savannah River Valley, and into the Lowcountry near where the frontal boundary should be, but it should be dry elsewhere in the state. Low ozone readings today, combined with clean sourcing to the north, should help to keep ozone levels in the good range. Thus, all zones should remain at CODE GREEN for Saturday.
