These strange 'clouds' were spotted by Mrs. Louella Blackwell of Baton Rouge, LA. Her son, James took
these photos and both were nice enough to let me use them.
Mrs. Blackwell says the sky was filled with these clouds as far as she could see from her house and they just
'faded' over time - after about an hour they were pretty much 'fuzz'. Once they did fade the night sky was clear.

Last I read my Meteorology books, clouds didn't come in tubes . What were they?
