Rain over Phoenix usually evaporates before it hit the ground so I am told.
and 3 inches of rain in store for Flagstaff through Tuesday.
I live in Chandler and we got over 5” in 5 hours. That is more than we usually get in an entire year....
I heard that the rain has not been falling in metro Phoenix for years because it is such a heat sink. Too bad, further south we get lovely lightening and thunder storms with heavy but brief rains regularly through the summer monsoons. It’s exciting and a nice change from the sizzling heat. Some times it rains long enough for the temperature to change, too.
