    Is there an answer

    Radio announcer states that today the temperature is nought degrees. Tomorrow will be twice as cold. So what temperature could that be?

    Surely there can be no concept or logical meaning of "twice as cold"?
    If you measure temperature in degrees Centigrade, Kelvin/Absolute or even Fahrenheit (if back-level) then halving whichever figure corresponds in each temperature system is meaningless.

    So tell your radio announcer that s/he should stick to the day job and not attempt to be a weather forecaster!

    Nought degrees in your location likely means 0 deg C (freezing point of water).
    Average temperature your location is abt 15 deg C in July (known around here as swimming weather), or 15 degrees below normal.

    Therefore I would expect tomorrow's forecast to be -15C, which is more like our winter temperatures than yours.

    Time to change forecasters perhaps.

    The Fahrenheit and Celsius temperature scales are relative temperature scales and are both relative to the freezing and boiling points of water.

    If however we look 0 degrees Kelvin when all motion in matter stops or Absolute Zero so to answer the original question and assume that your announcer was talking in celcius
    (mentioning a temperature of zero) we know the following equaition:
    Kelvin = Centigrade + 273.15

    We know now that O C = 273.15 K therefore the temperature tomorrow is 136.757 K or -136.757 C
