If the system moves eastward, the cloud system will undergo further distortion into a cloud pattern called a comma cloud, shown in the second and third illustrations. Comma clouds appear in all sizes and shapes, depending on the development of the vorticity pattern.

Comma cloud- A low pressure cyclone will often have the appearance of a comma on satellite imagery. The low pressure center and warm front make up the head of the comma while the cold front makes up the tail. Cumulonimbus- A thunderstorm cloud that encompasses the lower, middle and upper levels of the troposphere.

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