A stratus cloud covers the sky on a gray afternoon.

Definition

Noun: A stratus cloud is a type of low-altitude cloud characterized by its uniform, gray, and often featureless layer that covers the sky like a blanket. It is typically dark and can cover large areas, often bringing overcast conditions, drizzle, or light snow.
