This fall, residents of Nyda, Siberia, found roughly 11 miles of giant snowballs along the coast of the Gulf of Ob. These bizarre snowballs vary in size from roughly that of a tennis ball to three feet in width.

The snowballs form as the ocean water freezes into slush and waves roll them along the beach. That rolling from the waves causes the balls to form. They're rare, though they do happen, and similar snowballs have reportedly occurred along the Lake of Michigan.

These Siberiansnowballs could mean crazy cold for North America

Thanks to the way weather moves around the world, North Americans can often look towards Siberian fall for a prediction of the upcoming winter. The crazy cold that produced these snowballs is expected by some meteorologists to generate a polar vortex.

What does that mean for readers living in Canada and the U.S.? Brace for a cold winter. Word has it that we'll feel the effects in January. I'm stocking up on hot chocolate just thinking about it.
