It’ll never get that cold here. Not in my lifetime probably. Although I guess I shouldn’t ever say never since the world is going through Global Cooling
In a month or 2 17 will be blistering hot for us! LOL!
I lived in Del Rio for three years and it got down to 27 one winter. Austin is colder.
Just make sure you have a good winter jacket. There is nothing between you and Canadian winds but a few barbed wire fences.
