For 5/20/2024
[ The forecast is updated daily by 3:30 pm EDT. ]
As of the mid-afternoon hours on Sunday, ground level ozone concentrations were trending toward peaks in the Green category across South Carolina and the Central Savannah River Area of Georgia. On Monday, high pressure will bring mild temperatures and more sunshine to the region. While ozone concentrations are expected to increase, the lack of precursors should result in another day where the Air Quality Index remains in the Green category for all zones.
