We should see a mixture of CODE GREEN and CODE YELLOW for ground-level ozone this Friday afternoon. The upper-level ridge over the southeastern part of the country continues to build over the region and it should continue building on Saturday. This may make air stagnation a potential problem in the Palmetto State. Northwesterly winds should be quite weak early, then become light and variable in the afternoon. With mostly sunny skies and hot conditions, ozone concentrations should remain elevated statewide. Thus, all zones should be at CODE YELLOW on Saturday.
