Man up and go to Vegas like I did, in July! It sucked so hard. I've never felt heat that intense. My phone even melted down.
Yes, rapid intensification is very unlikely, although everything depends on how much wind shear develops out in front of it. Because of forecast uncertainty, deep layer shear could be very high or almost nonexistent. However, 92L is forecast to go over some very warm loop currents, which could aid intensification. Worst case: moderate TS. Best case: open wave.
Man you are not kidding about that. I was there last July and the "dry heat" was insane. Just walking on the side of the street was unbearable.
