Cyclones on Satellite Images
comma-shaped cloud configuration

On satellite images, a midlatitude cyclone is often identifiable by a comma-shaped cloud mass.

A single cyclone can influence the weather over a large area, (in this case from Texas into Minnesota). This particular storm (in the satellite image above) left more than six inches of snow from Nebraska into Minnesota, while heavy rains occurred from Missouri into Texas.
