Forecast Discussion: [View the ADEQ Hourly Forecast for Phoenix]
As expected, PM2.5 ended the up in the low Moderate AQI category yesterday, while the other pollutants were in the Good range. With a weather system currently moving through the area, we forecast all pollutants to be in the Good range today and tomorrow. The Phoenix airport has reported 0.03 inches of rain this morning and we will likely see more scattered showers through the day.

A brief period of calmer conditions on Thursday may allow PM2.5 to return to the Moderate AQI range, but the other pollutants should easily remain in the Good range. Another trough moving through Friday and Saturday should provide enough ventilation to bring all pollutants back into the Good AQI category.
