My Sisters and I were just children and grew up in this stuff from a long time ago.
My Sister in California , when told it was 1 degrees for the high said...."That is booger freezing weather."
Meaning, it is so cold, the inside of your nose, and everything in it, instantly freeze when you step outside and inhale.
"rolling clouds"I was scratching my head on my porch thinking "Is that a sand storm??"
But they are just clouds. Never saw them do that before though.
