They don't quit using it. There's an algorithm for calculating the heat index based on the relative humidity.
If the humidity is low enough, the multiplier to get the heat index is 1, heat index=ambient temp.
As the humidity increases, so does the multiplier.
I have no idea below what humidity level cut-off is, or how it changes for chill factor, which is based on wind speed. (Maybe humidity also???)
It's also based on humidity.
