Ozone concentrations had risen well into the yellow criteria over the CSRA and the middle and northern part of the state as of the mid-afternoon hours on Friday. Readings along the coast and into the Pee Dee were lower as the air mass had a cleaner, oceanic history. Saturday's readings are expected to be similar, with yellow criteria readings again expected over all of the state except for the Pee Dee and coast.
