Not that I want to start a thread drift, but personally I don't believe in "Wind Chill"
I understand the theory, but the way I look at it, television stations are in a desperate race to increase their ratings, and everyone knows that the more extreme you make a number, the more Americans like it
But you can't exactly lie on what the temperature was/will be, so some clever people said, let's lie anyway, but give ourselves some "plausible deniabilty" to quote an ex president of a certain political pursuasion
.
Thus was Wind Chill Factor born.
If you don't believe that, then why after aq while did they also invent The Humidity Index? - "Here in Dallas, it was one hundred and five today, but the humidity index made it feel like one hundred and twelve.".
It's just marketing, that's all
