Trust me, this thing will be a failure; the only debate will revolve around how much of a fail it is (slight, or severe).
Think about it. The previous arctic blast this month was supposed to bring SE TX the first freeze of the season, and yet temps didn't even get close to freezing (no lower than 38-39F), not even the areas north of I-10 were the freeze warnings were. Denton was supposed to be in the teens, and yet it only bottomed out in the lower 20s.
The forecast is basically hanging on the thread that is US snowfall cover. From what I see right now, there doesn't appear to be too impressive of amounts over the country. All that bare land can make all the difference in regards to cold front moderation, and things can be quite exponential if enough of that land remains:

And where is the HP and it's trajectory? That can make all the difference in regards to how cold Texas gets; from what I've seen, it looks to be too far east up north, meaning that there'd have to be a westerly component to the trajectory in order to strike Texas the way it has to for the forecast to be correct, and as we've seen, weather has a west-east trend during the fall-spring period:

Of course, they are always fine-tuning these temperatures based on real-time trends, so they still have to chance to make the necessary corrections to be as accurate as possible.
