Ground-level ozone is trending toward peaks in the code GREEN range across the state on this Thursday afternoon. Meteorological factors affecting ozone production won't change much from Thursday to Friday. Very warm and humid conditions will persist under partly to mostly sunny skies along with a slight chance of an afternoon thunderstorm in most places. Winds will organize a bit more from the southwest, improving dispersion and bringing in relatively clean air from upstream areas. Thus, ozone production should remain rather steady from Thursday to Friday, with code GREEN conditions expected in all forecast zones.
