Forecast Discussion: Ozone levels remain on the low side this Friday afternoon in spite of sunshine due to low precursor concentrations. Ozone levels will be on the rise over the next couple of days with very warm and humid air advecting in from the southwest. Initially, cloud cover will keep ozone in the upper good range Saturday into Sunday with a warm frontal passage. With more sunshine and heat coming in next week and minimal chances for rain, ozone concentrations in the moderate range are likely by the middle of next week.---McAuliffe
