The Chart For Wind Chill Should Be Huge !
I never get steady wind, it's usually gusty. If it's 15mph, gusting to 27 mph, the weather guessers use the higher speed to tell the "real feel," but it's wrong.
Different clothing allows different amounts of wind penetration. Then there's ground obstructions, varying direction, and humidity and . . .
. . . the Wind Chill chart should be huge. That's why it doesn't work for me, it doesn't help, too many factors. It's for exposed flesh and I never go outside naked . . . well . . . never mind, don't ask.
Detroit had a famous TV weatherman, Sonny Elliott (meteorologist), on for years. He died recently. I read that he shared my feelings on Wind Chill, hated it, thought it a joke.
When it's cold and windy, it can feel colder on exposed flesh than when it's just cold. That simple.
