Weather Wonders: Mammatus Clouds

(KSLA) -

This week's Weather Wonders focuses on one of my favorite cloud types - Mammatus clouds. We've received quite a few photos over the past few months of these unique looking clouds with many wondering exactly what they are. 

Mammatus clouds are pouch-like extensions off a cloud base. Many people say they look like cow udders. These unusual clouds are actually formed in a rare way by sinking air. Most clouds are formed by rising air. This cool sinking air, usually after a strong storm, collides with warmer air below forming the rounded pouch shape. 

Although, they look ominous, Mammatus clouds are usually formed after the severe threat has passed, and they are not an indicator that a tornado is about to form.
