Hole punch clouds

Holes in cloud decks are formed when supercooled water droplets in shallow cloud layers freeze (initiated by the falling ice crystals) and release their heat of fusion, which warms the air and evaporates the surrounding cloud. The fibrous, icy wisps falling from the clouds are called fall-streaks (seen here at left in the shape of a butterfly)
It's a day for weather I guess. I saw a picture of a cloud formation in September's issues of National Geographic. I've neither seen nor heard of this kind of formation before. Aussie School House has a whole collection of pictures of 'em. The National Oceanic & Atmospheric Administration has an explanation, but National Geographic says, no one knows for sure how these are created, except that it's certainly not by the action of alien spaceships. "UFO hunters be warned�there is probably a perfectly reasonable explanation for the massive holes that mysteriously form in cloud layers as if, well, a giant spaceship had blasted through. Scientists just haven't nailed it down yet."

I substituted the National Geographic's actual words for my paraphrase.
