Not that you are wrong or anything, but I'm curious where you have your weather station.
Was only 108 at my house in Chandler, 106 at AZCentral...hard to believe it got to 115 at your house, but not everywhere.
Which brings up an interesting question.
Official records for PHX are taken at the airport.
Where at the airport are they taken?
In the middle of the the (concrete) runways, at the tower, somewhere in the riverbed?
