Forecast Discussion:

Sky Harbor International Airport only reported 0.07 inches of rain yesterday, certainly less than anticipated, however, it was enough to keep all pollutants in the Good AQI range. PM10 levels are quite low this morning due to more stable soils from the rain. PM2.5 is a little elevated this morning, but the day should still end up in the Good range.

Looking ahead, another trough over the weekend could bring light rain late Sunday and Monday. With the rain yesterday and more rain this weekend, PM10 should remain comfortably in the Good AQI range through the forecast period. We also forecast PM2.5 to stay in the Good range due to generally Good ventilation from the trough that will be moving through.

No issues with ozone, still too early in the year for ozone to be a concern.
