Well, it is 100 miles from here to Grapevine, but Mother Nature makes little of the distance. I was outside, a necessary trip to one of those "mostly big box" shopping venues yesterday afternoon at 4PM. The weatherman said it was 106F. My amazingly accurate car's gadget rang in at 110F. It felt about 3 degrees below boiling point, and the asphalt was tacky.
I'd find a comfortable, cool, dark lair at DFW, 'cuz for all of the appeal of downtown Grapevine ;-), it ain't worth a few hours on Hell's doorstep.
