Far West Texas, and New Mexico are in for rapidly changing conditions characterized by warm weather transitioning to very cold with heavy snow and blizzard conditions. Farther east in Austin, a generally fast moving squall will form and blast through the I 35 Corridor in a rather short time followed by breezy and colder.
Heavier rain will be found in the usual regions: Coastal sections, Houston, East Texas, Louisiana, and Oklahoma, where snow will develop as well, This is going to be memorable everywhere in the southwest US except for Austin lol, unless you like high winds and tornadoes. I'm crazy, but I am not one of those fkin crazy nuts that likes tornadoes.
To sum up: I'm damn glad I'll be getting the hell out of this southwestern climate in a few short days.
I prefer cloudy rainy weather and flooding.
The farther east and north from Austin one travels, the more steady and heavy rain one shall find. In the more northern areas, rain will change to snow and pile up and blow around. The northern guys can have the snow. I enjoy rain and lots of it.
