Ground level ozone concentrations are trending towards peaks in the YELLOW Upstate and Catawba and GREEN elsewhere. High pressure will remain in control of weather conditions on Friday. Mostly sunny skies and rather light winds from the north and northeast direction should make for efficient ozone production conditions, while ozone precursor emissions increase slightly in South Carolina as the state will be sourced from a dirtier region currently over the Mid-Atlantic. As a result, expect ozone to climb to mid yellow in Upstate and Catawba, the I-20 corridor will likely peak near the GREEN/YELLOW threshold, and Trident should remain GREEN on Friday.
