It's not uncommon in the summer for the overnight low in Phoenix to drop all the way down to 95. It's a dry heat, but then again so is your oven.Heat and humidity will make you lose your ******* mind. Definitely get a war in the south over that...lol.. **** some nights you can walk out at 10 pm and start pouring sweat in 5 min. I get really cranky when I'm overheated.
