A meteorologist would never make such a statement because it's meaningless. Two times zero is still zero.

If someone on the weather channel says it will be twice as cold tomorrow and it dropped 5 degrees between today and yesterday. Then if it was 0 degrees today, they most likely mean that tomorrow it will be -5 degrees.

"Twice as cold" and their ilk are always meaningless statements, no matter the temperature. You are mixing terminology (like saying something is twice as short - it makes no logical sense), so it will always be as confusing. What is twice as cold as 20? 10? No, that is half as far above freezing that weird mixture. But let's suppose that he really meant half as warm. I assume you mean 0 F, so that's 255 K above absolute zero. So I guess that tomorrow it will be -200 F.

Kind of a stupid thing to say, it could however be interpreted as follows:
0 is 32 degrees below freezing so twice as cold would be 64 degrees below zero of -32 degrees, but that supposes that the freezing point of water in the comparative point.

The only way twice as cold can be calculated is using absolute temperature or the Kelvin scale that starts at absolute zero, -273oC. OoC =273K

Nature Boy is correct. Weather channels will never say that in their forecast. They may say , "It may be a lot colder tomorrow." They may also give the numbers of their forecast for the next day.

It's merely a figure of speech. It's just gonna be chiller. It could still be 0^F tomorrow, but the wind chills could make it feel like -5^F or so. Hope this helped.

Take it as 00 degrees for tomorrow.
