-20F?

Friday on the flight from JFK to Minneapolis, all passengers heard to their astonishment:
"Here is the captain speaking. Due to the 70 mph winds, we have to make a gas stop in Green Bay, but we'll be back on our way in no time."
A gas stop? In mid-air? Nobody could believe what they were hearing. I felt like being in the Arctic outback, which came to be true once in Minneapolis. Friday night Minneapolis -20F I don't know how cold it would be calculating the chill factor. The sun shone bright all day, the landscape beautiful to look at. But the winds were blowing right through my bones! No exposed skin allowed outside! Chances of bitefrost were extensively discussed on TV. A new day, a new world!
