Welcome from Mississippi. I'll take the heat & humidity any day over the cold, ice & snow. As a homesteader prepper, IMO the warm climate areas will be the easiest to survive after a crisis. One can adjust or get accustomed to the warm temps and is much cheaper/simpler/safer to get thru our short, mild winters. Those areas with more rain (and thus more humidity) are certainly tougher for some to handle in the summer but those locations are best for growing your own food when needing to become more self reliant. Humidity makes the hot weather worse but those areas get lots of rain... something necessary to grow your own food. So the dry areas of Texas, say west Texas, will be more comfortable but the wetter areas will be easier for crop production.
