I design buildings. The differences in the building codes between Texas climate zones and ND climate zones are huge as far as insulation requirements are concerned. Nothing here is designed to be in this cold of weather for this long. It is all failing. Water utilities need parts to fix pumps that froze, but can't get any because truck aren't running again yet, because the roads are a mess and we don't have plows and salt trucks. Same for grocery stores, no food because no trucks. I lived in Minnesota for a while and the opposite is true there. The worst week I was there, the temps were -20 with wind chill -40. It was cold, but those buildings are designed to withstand it. They don't do well in heat above 90 though, as a lot of homes don't even have A/C, just heat. It's not about our "weak side", you have to consider the actual physical differences of the regions. I'd be curious to see how well you fare after a week of 100+ temps with 95% humidity. It's like living in a sauna.
