South Texas? We lived in San Antonio for last 5 years, and the weather does not really get extreme. Well you get consecutive weeks of 105-110 highs in summer. But it is far enough from the gulf coast so no hurricanes, and apart from the 2021 snowpocalypse, we didn't get any extreme weather. Austin is also okay. If you get too far north up to Dallas you start to get the snowstorms and tornadoes though.
