This week, ozone has reached the Moderate AQI category in Prescott every day, even despite strong daytime breezes. Because of this, ozone is forecast in the Moderate AQI category again today. We'll also keep ozone in the Moderate category Friday through Monday, given the potential for regional ozone levels to stay somewhat elevated. But, we'll watch for any changes in ozone trends.
