Forecast Discussion:
Flagstaff remained in the Good AQI range through the weekend. Ozone levels will be lower the next two days because of additional cloud cover and rainfall. Starting Wednesday, there will be an increase in daily ozone levels because more sunshine is forecast while high pressure moves into the area.
