Ground level ozone is trending towards Yellow in the Upstate on this Wednesday afternoon. Other zones should remain GREEN, but there is a still a chance of an isolated yellow in one of the more inland zones. High pressure will remain situated over the Mississippi Valley region on Thursday. A weak northwest flow will meet up with deep layer moisture situated along the coast. A fairly dry airmass, laden with more precursors, should allow portions of Upstate and Catawba to reach CODE YELLOW criteria. Concentrations along the I-20 corridor will likely push near the GREEN/YELLOW threshold in a battle between weak flow and higher moisture content. More moisture closer to the coast should lead to GREEN concentrations in Trident.
