There's a huge difference between describing average temperatures (what people describe as 'global warming') and describing the temperatures on any specific day.
Previously, a strong jet stream air current trapped cold polar air far north of Texas (which is say 30' North latitude). As the pole's warm, the jet has become pone to weakening allowing cold polar air to move very far south e.g. 90'N to 30'N in Texas, which sits east of the rocky mountains in the US.
Effects like this are why a lot of people are using the term 'climate change' more frequently. Because an increase in CO2 means more than just an average higher surface temperature. Weather changes and instabilities will grow more common, with a bias to warmer events over all.
Think of it as the 'variance in the weather' is growing along side the mean weather (temperature) is going up.
Yes, as an American I'll agree our politics has plenty of instabilities as well.
If you don't mind can you read this article about SSG (which is what caused this weather event, noted in January)

A large factor in the strength of the jet stream is the temperature differential between polar regions and lower latitudes. It's well known at this point that polar regions are warming the fastest, so there is a smaller differential, and the hypothesis goes that this can weaken the jet stream, leading to more events where the polar vortex dips down much further than normal.
This is a great article explaining that hypothesis: https://www.washingtonpost.com/opinions/2021/02/18/texas-pow... . Note the author of the article actually thinks the evidence for that hypothesis isn't very strong, but believes it's certainly possible and that its proponents are arguing in good faith.
I would like to read it
I just get bothered when see co2 makes things cold, its almost absurdist joke ie the one thing to nullify a hypothesis is now incorporated into the hypothesis to strength the argument.
I don't know anything about Texans, I don't even live in America but American politics trickle down
