**Ground Level Ozone Action Day for Central Savannah and Midlands regions on Wednesday**

Most regions are trending toward code yellow on this Tuesday. For Wednesday, temperatures should increase several degrees and moisture will increase slightly. The high pressure system in the southeast U.S. will mean light southwest winds across most areas with little dispersion. Source regions provide a pollutant-loaded airmass that will help all regions to increase from today. Therefore, CODE ORANGE for the Central Savannah and Midlands regions; CODE YELLOW in the Upstate and Pee Dee regions; and CODE GREEN for the Catawba and Trident regions.
