Texas, maybe? If the power grid goes down because of excess AC usage? Yes, I read that people have been living for 100s of years (pre-AC) through temps regularly hitting 46 degrees, but see also the response on wet-bulb temps and survivability. 46 degrees for 5 days straight without AC (as in, backup power is gone...) and I think we'll see some losses. Europe regularly sees large deaths due to heat during summers already today, true mostly in elderly.
