If it's zero degrees outside today and it's supposed to be twice as cold tomorrow, how cold is it going to be

Just curious.

While this may be an interesting question, it is not valid - the question is, "Twice as cold related to what?" If you relate it to "comfortable" - say, 70 degrees - then tomorrow expect minus 70 degrees - quite a drop for under a day! This might be possible in Alaska, but I doubt it will ever happen here in the "Lower 48". If you related it to, say, a "comfortable" 40 degrees, then minus 40 might be possible, but that's still unlikely in most areas except in the dead of winter.

So bottom line, I would say it's not a valid prediction, just an exaggeration.

-2, I guess..
