-48 air temp in Chicago?
Seems a bit of a stretch

-20ish is a bit more realistic but at that point it may as well be -100.
and her comments about -84 wind chill.... sometimes as we get older the stories have an embellishment due to ‘fond’ memories.
Not only are the temps ‘a bit of the stretch’ the fact that she didn’t comment on the severe frost bite that she got says it didn’t happen. My fingers were frost bitten in a particularly nasty storm during my teen years. To this day I do not like handling ice cubes or other cold things. I wear gloves often (even on warm days).
That was the wind chill back in 89 I believe. It was cold enough to kill you in minutes.
