Cirrus Uncinus
The name cirrus uncinus is derived from Latin, meaning "curly hooks". Also known as mares' tails, these clouds are generally sparse in the sky and very thin.
The clouds occur at high altitudes, at a temperature of about −50 to −40 °C (−58 to −40 °F). They are generally seen when a warm or occluded front is approaching. They are very high in the troposphere and generally mean that precipitation, usually rain, is approaching. From Wikipedia
When its 'fall streaks' are the shape of hooks or commas. The top of each comma is thicker than the tail, but does not show any clumps or mounds on its upper side. Cloud spotter's Guide
