Gimme a little time and I'm come up with it. "The Herring Croon," by Gordon Bok.

I think you'll find that's "mare's tails and mackerel skies."

Description of cloud formations. Mare's tales: wispy clouds, long and strung out. Mackerel skies: do look a bit like fish scales. Small, "chunky" looking clouds and lots of them.

Folks from the Maritimes or Down East know more about this than I do, but I think both cloud formations indicate bad weather coming.

I'll get the words and be back in awhile.
