Forecast Discussion:

Ozone levels ended up in the low Moderate AQI category yesterday and we aren't expecting any major changes going forward. Ozone is forecast to trend up a little over the weekend with high pressure strengthening over the region. Then, ozone is forecast to drop down a little on Monday with another weather system beginning to move into the region. Overall though, we are forecasting ozone to stay in the Moderate category through the forecast period.
