Forecast Discussion:

A decent spread of precipitation can be seen from observations across central AZ, with potentially more on the way today. An upper level shortwave is currently centered over northwestern Arizona, and will take another day to exit the region to the east. This means light chances for precipitation will continue for today and tomorrow, with potentially some rain occurring in southern Arizona tomorrow.

What this means for air quality is an overall improvement of particulate matter after tomorrow. A drying trend will ensue afterwards, and will need much more rain for us to get out of our dry spell. For now, we'll take what we can get!

Have a great Tuesday!
