Forecast Discussion:

All pollutants ended up in the Good AQI range yesterday and we are forecasting the same today. Ventilation should be improving over the area with a trough moving into the region. This weather system will bring stronger winds tomorrow, which will likely kick up a little dust. Therefore, we are forecasting particulate levels to reach into the low Moderates. Late Thursday and into Friday morning, we are expecting some rain to move through the Tucson area. This should improve pollution levels quite a bit on Friday. With more stable soils from the rain, we are forecasting particulate levels to remain in the Good AQI range through the weekend.
