Forecast Discussion:

Tucson observed its first Moderate ozone day of the year yesterday, marking the latest date to reach at least 55 ppb (Moderate AQI) since 1975. Today has a shot at reaching low Moderates again, but increasing cloud cover today may end up suppressing ozone formation enough to keep it in the Good range. After today, ozone is forecast to improve due to better ventilation as a trough skirts by to the north. This is forecast to keep ozone in the Good range through the end of the forecast period. PM10 is forecast to remain in the Good AQI range and we don't anticipate any issues in the foreseeable future.
