Weather Condition:
Weather Indicators: Strongly sprouting Cumulus with generally sharp outlines and often great vertical extent. The bulging upper part of Cumulus congestus frequently resembles a cauliflower. Cumulus congestus may produce precipitation in the form of showers of rain, snow or snow pellets. In the tropics, they often release abundant rain in the form of showers.
Cumulus congestus sometimes resemble narrow, very high towers. The tops of these towers may detach themselves successively from the main body of the cloud. They are then carried away by the wind and usually rapidly disintegrate, occasionally producing virga. From International Cloud Atlas.

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
