Thunderstorm vs. Thundershower — What's the Difference?

By Urooj Arif & Maham Liaqat — Updated on April 16, 2024
A thunderstorm is a weather event characterized by thunder, lightning, and typically heavy rain, while a thundershower implies a lighter, less intense version of a thunderstorm, usually shorter and with less precipitation.

Difference Between Thunderstorm and Thundershower


Key Differences

Thunderstorms are intense weather phenomena involving strong winds, heavy rain, lightning, and thunder, often developing in cumulonimbus clouds. On the other hand, thundershowers are milder and typically result from less severe weather conditions.
Thunderstorms may lead to severe weather effects such as hail, strong winds, and tornadoes, indicating a more robust and hazardous weather system. Whereas, thundershowers are generally associated with brief periods of rain and occasional thunder and lightning, posing less risk.
The formation of a thunderstorm requires specific atmospheric conditions, including high humidity, rising unstable air, and a lifting mechanism (like heat). In contrast, thundershowers can occur with less distinct atmospheric conditions and might not require as strong a lifting mechanism.
Thunderstorms are more likely to cause significant meteorological impacts, such as flash flooding and electrical outages, due to their intensity. Conversely, thundershowers are less likely to lead to severe impacts, typically amounting to light to moderate rainfall.
While thunderstorms are often forecasted with specific warnings due to potential dangers, thundershowers might only be indicated as a chance of rain and thunder in weather predictions, reflecting their less threatening nature.

Typically involves less precipitation and wind.
The thundershower brought just enough rain to water the gardens.


A thunderstorm, also known as an electrical storm or a lightning storm, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Relatively weak thunderstorms are sometimes called thundershowers.


A brief rainstorm accompanied by thunder and lightning.


A storm with thunder and lightning and typically also heavy rain or hail.


A rain shower accompanied by thunder and lightning.
The thundershower poured down on us as we ran home, but returned to a drizzle after several minutes.


A transient, sometimes violent storm of thunder and lightning, often accompanied by rain and sometimes hail.


A shower accompanied with lightning and thunder.


A storm consisting of thunder and lightning produced by a cumulonimbus, usually accompanied with heavy rain, wind, and sometimes hail; and in rarer cases sleet, freezing rain, or snow.


A short rainstorm accompanied by thunder and lightning


A storm accompanied with lightning and thunder.


A storm resulting from strong rising air currents; heavy rain or hail along with thunder and lightning

Common Curiosities

Can thundershowers become thunderstorms?

Thundershowers can escalate into thunderstorms if atmospheric conditions intensify.

How long does a thundershower last?

Thundershowers generally last for a short period, often less than an hour.

Is lightning more common in thunderstorms or thundershowers?

Lightning is more common and intense in thunderstorms compared to thundershowers.

Do thunderstorms occur worldwide?
