7 degree windchill tomorrow morning in New Orleans

9. So our temps in San Antonio are gonna be the same as NOLA's. Wind chill shouldn't affect pipes.

Of course it depends on piping, pipes location and the foundation. If they run water over night, pipes likely won't burst.

My daughter's pipes burst in 2021, but that was after 5 days below freezing and no electricity. She lived in a 110 year old home.
My son's pipes didn't burst and he also lives in a 100 year old pier and beam home. His pipes didn't freeze because the previous owners had switched the pipes to PEX.
Our neighbors who installed a water soften had their pipes burst because pipes were rerouted into the attic for the water softener.
None of our pipes burst. We're on a slab.

All of these involved extended days of freezing, lack of electricity for several days and non-functioning heat sources due to lack of electricity.
