Forecast Discussion:
Ozone is forecast to continue in the mid Moderate range for the next few days. Light breeziness should be enough to prevent ozone levels from ramping up too much, but not enough to totally clear out the airshed either. A trough will begin to move into the region on Monday and Tuesday, which should improve ventilation and lower ozone into the lower Moderates. As for PM10, there are some unusually elevated concentrations this morning, but we expect that to improve over the next couple hours. We forecast PM10 to drop into the Good AQI range on Saturday and Sunday due to less dust generating work activities. Then, as we return to the work week, we forecast PM10 to move back up into the Moderates on Monday and Tuesday. The elevated particulates mentioned above are also affecting PM2.5. This will likely result in PM2.5 also reaching into the Moderates today. It should be noted though, these unusually elevated particulates this morning are isolated near the South Phoenix monitor. After today, we forecast PM2.5 to stay in the Good AQI range through the remainder of the forecast period.- R. Nicoll
