For 7/7/2025
[ The forecast is updated daily by 3:30 pm EDT. ]
All regions are trending code green on this Sunday. For Monday, the "calm after the storm" becomes reality as clouds, precipitation, and moisture all exit the region. This also sets up a light west/southwesterly wind which means pollutants will not disperse nearly as easily as Sunday. This, plus a dry atmosphere and super sunny skies, mean ozone production will be efficient and increases are imminent. Clean background concentrations will help to offset some of that production, but overall, the Midlands, Upstate, and Central Savannah River areas will likely be CODE YELLOW as other regions should be CODE GREEN.
