It matters not what part of the world you live in. If you see clouds like this, the weather is about to change. Yesterday's early sky foretold of today's coming snowfall. You could see the Cirrus uncinus clouds everywhere! The name cirrus uncinus is derived from Latin, meaning "curly hooks" and they're also referred to as mares' tails, a term given them by farmers years ago. They are often a telltale sign the weather is going to change within 24 to 48 hours.
