The National Weather Service has posted their Month In Review for August, 2012. The report includes the graphic below comparing August 2012 precipitation to historic numbers.
There are very wet areas. There are very dry areas. The Monsoon Season rarely results in uniform distribution of rainfall. I think looking at rainlog.org helps show this reality of the Monsoon Season. Looking across Northern Arizona, we see wide variability. I know I kept wondering if the weather station at the Flagstaff Airport had its rain gauge under a tree. They reported less than 3 inches while the eastern and northern areas of Flagstaff reported considerably more than 3 inches. It matches the division to the south and east in the image above.
If you look down around the Prescott-Sedona area, you can note several locations above 4 inches and several locations under two inches. one spot near Clarkdale had almost 6 inches. Another site near Prescott recorded only 1.1 inches. It's just how the Monsoon Season works.
For the next few days, most of Northern Arizona will be wetter than normal. If you have ever been to the Killer Whale Show at Seaworld, you already know the saying "you will get wet, you may get soaked." If you have a chance, buy a high quality rain gauge and report your rain at rainlog.org.
