Ozone levels have been moving into the Yellow category across the CSRA, Midlands, and Upstate areas this afternoon. The Pee Dee and Catawba areas may see isolated Yellows as well. The ridge that has developed over the southeast will strengthen tomorrow leading to stronger southwest flow across the state. The stronger flow will bring in more moisture from the Gulf returning us to more normal atmospheric moisture levels for this time of the year. Despite the increased moisture and stronger winds tomorrow, the Upstate still could reach into the YELLOW category. The rest of the state should stay in the GREEN category.
