Ground level ozone is jumping near the inland urban areas on this Wednesday afternoon. Upstate, Midlands, CSRA and Pee Dee will likely peak in the yellow category. Only subtle changes are in store for Thursday as upper level and surface trough axis remains situated over the Appalachian mountains. With east Georgia and the Carolinas remaining on the eastern flank of the trough, a bit more moisture is expected with more maritime sourcing expected. The slight moisture increase should limit ozone production somewhat, however, light winds may allow urban precursor plumes to concentrate nearby the urban centers allowing most regions to peak YELLOW on Thursday. Trident should remain GREEN.
