Ozone levels topped out in the Good category over the weekend. Clearer skies prevail this morning, and cumulus will develop later this morning.
Today's forecast includes isolated showers/thunderstorms this afternoon as well, but the coverage will not be enough to impact ozone levels much. Tomorrow's shower/thunderstorm activity is forecast to be near Flagstaff which may keep Ozone levels lower. Ozone levels may fluctuate depending on daily shower/thunderstorm activity. The current forecast will continue to hover around the upper Good/lower Moderate AQI range for the next several days.
