Most thunderstorms come and go fairly uneventfully; however, any thunderstorm can become severe, and all thunderstorms, by definition, present the danger of lightning. [88] Thunderstorm preparedness and safety refers to taking steps before, during, and after a thunderstorm to minimize injury and damage.

Illustration of a microburst. The air moves in a downward motion until it hits ground level. It then spreads outward in all directions. "Dry downbursts" are associated with thunderstorms with very little precipitation, [28] while wet downbursts are generated by thunderstorms with large amounts of rainfall.
A storm seen at the Baltic Sea near the island of Öland, Sweden.. A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. [citation needed] It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain ...
Thunder and lightning are much more common in warm, summer months because of convection, the upward motion of air that helps produce thunderstorms. Because convection is rare in winter ...
Of the four classifications of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the overall least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms, and can dominate the local weather up to 32 kilometres (20 mi) away. They tend to last 2–4 hours.
Generally, thunderstorms require three conditions to form: moisture, an unstable airmass, and a lifting force (heat). All thunderstorms, regardless of type, go through three stages: the developing stage, the mature stage, and the dissipation stage. [11] [better source needed] The average thunderstorm has a 24 km (15 mi) diameter. Depending on ...
A dry thunderstorm is a thunderstorm that produces thunder and lightning, but where all or most of its precipitation evaporates before reaching the ground. [1] Dry lightning refers to lightning strikes occurring in this situation. Both are so common in the American West that they are sometimes used interchangeably. [2]
