Forecast Discussion: Ground level ozone concentrations were well within the green category as of the mid-afternoon hours on Tuesday. With low pressure slowly exiting to the northeast, values will remain in the green range the rest of the day. Concentrations are expected to rise into the low end of the yellow range over the Upstate on Wednesday as high pressure builds in from the west, bringing sunny skies and a slightly dirtier air mass. The rest of the state is expected to peak in the high end of the green range.
