Forecast Discussion: [View the ADEQ Hourly Forecast for Phoenix]
The rain has certainly begun, and as a result, air quality levels are great this morning! Sky Harbor has reported about a half inch of rain so far and we're not done yet. With rain continuing off-and-on through tomorrow, all pollutants should remain in the Good AQI range today and tomorrow. PM10 is forecast to remain in the Good range due to the rain helping suppress any loose soils in the area. However, we forecast PM2.5 to return the Moderate category for Friday through the weekend. With calm conditions and cooler temperatures after this weather system moves through, we anticipate an increase in wood burning activity, which will increase PM2.5 concentrations. Ozone will stay in the Good AQI range as it's too late in the year for ozone to be of any concern.
