Ground level ozone concentrations remain in the green category on this Friday afternoon as a tropical airmass remains in place across the region. Very little changes as we head to Saturday as large-scale features move little and low level winds also move little. Even with light and variable winds and only a slight chance of precipitation statewide, ozone will struggle to recover from the cleansing from recent days within a continued tropical airmass. Thus, all zones are expected to remain Code GREEN on Saturday.
