For 6/15/2025
[ The forecast is updated daily by 3:30 pm EDT. ]
Ground-level ozone monitor readings on this Saturday afternoon are on track to peak well within the code GREEN range. On Sunday, the overall weather pattern will change very little. As such, the main factors that will continue to suppress ozone production will be the very humid air mass and influx of relatively clean air from the south or southwest. Any showers or thunderstorms that develop will also suppress ozone formation. Thus, code GREEN ozone conditions are expected once again in all forecast zones on Sunday.
