Yes, there were sub zero temperatures in Dallas last night.

  How badly are your homes insulated that you get internal=external temperature in mere hours???

    It has been a day or two, right? (Former Minnesotan, now living in Hong Kong, so slightly out of it, but familiar with -20F/-30C and occasionally -40F/-40C.) I think enough air circulation to avoid your breath causing mildew everywhere will mean without a ton of thermal mass, your house is going to get within a few degrees of the daily high within a day or two.

    Shut off your heat for a couple of days and report back.

    It's been going on for a lot more than just a few hours.
