Euphemisms for "cold"

It is alleged that the Eskimos have twenty-seven different words for snow, even though that is dismissed in some quarters as an urban myth. But maybe it's an urban myth that it's an urban myth, who knows?

Either way, I usually pay a bit of attention to the weather forecast and I have the definite impression that weather forecasters are coming up with lots of new words or phrases to express the basic idea of "cold". For example, on today's Channel 4, he described the wind as "nagging" (which I thought was quite poetic). Then there are words like crisp, biting, fresh and so on, which I've heard quite a few times recently.

Another commonly used term is "below average temperature", which seems a bit politically correct, as it implies that the "real" temperature is constantly going up because of something called "global warming", so while it seems cold, that's only because there's a downward blip and actually it's much warmer than you think.

Or maybe they just do it because they get bored stupid just saying "cold" all the time, in the same way as football commentators use dozens of different euphemisms or synomyms for "ball" or "goal".

But as with all these things, I wonder whether I am imagining this or weather everybody else has noticed any cool new euphemisms for "cold" as well?
