This just one more variable that could be affecting our weather. I was reading about the deforestation and know that the plateau area is the birthplace of the Texas cap. Nothing in the atmosphere happens in isolation. Maybe I could start another thread with this, but the last time I did I didn't get any responses. Maybe they should paint the whole area white to cool it down to weaken the cap.

I'm convinced that situations like you reference have at least
some impact on the real weather. That is a real interesting thought,
horselattitudesfarm, and something probably worthy of greater research. It has already been proven that things like the urban heat island effect have bearing on real weather, so I don't see why a variable like this wouldn't. And at least anecdotally it seems like our spring severe season at least in south central Texas isn't anything like it was 10-15-20 years ago.
This might be something to post in the Texas Spring thread as we start to kick around weather ideas in March.
