I find it amusing that the more TX tried to be different from CA, the more TX resembled CA.
We get those kind of warnings in CA also. Just not in June when summer hadn't even started yet. We got those around August and September.
We definitely didn't get those warnings when the weather was in the balmy 95s. We were generally well into three digits temperature before we received those kind of warnings. Or three digits temperature in combination with wild fires.
