Forecast Discussion:

Today we'll see more of the same as we have all week. Cool mornings followed by warm afternoons with light winds. Tomorrow, our tune will shift slightly as strong east-southeast winds move into Arizona. Winds will range from 20-30 mph for sustained speeds, but higher gusts are possible. These winds are expected to last through the morning, afternoon, and evening hours on Friday. A few breezes may even appear early Saturday morning as well.

As we continue through the weekend and into next week, conditions will revert to calm winds with cool mornings and warm afternoons. There is another system looking to dip down from the north around Tuesday/Wednesday next week. The track of this system could change between now and then, but hopefully, we'll see some additional moisture brought into the state!

In regards to air quality, PM10 and PM2.5 should remain in the Good Air Quality Index (AQI) category today. With the strong east-southeast winds expected for tomorrow and recent dry conditions, we did bump up particulate levels to the Moderate AQI category. Over the weekend and into next week, both PM10 and PM2.5 should drop back into the Good AQI range. There are no concerns with ozone at this time.

Have a great day!
