Isolated thunderstorms are thunderstorms that occur individually, covering a small, localized area rather than spreading over a large region. They tend to be short-lived, mostly vertical in structure, and usually do not produce violent weather at the ground level

. These storms often develop where there are light winds that do not change much with height and where there is abundant moisture at low and middle atmospheric levels

. Key characteristics of isolated thunderstorms include:

• Small coverage area, affecting fewer people compared to scattered or widespread thunderstorms

• Short duration, typically lasting less than an hour

• Usually associated with cumulus clouds and can be easier to avoid, though they may still produce lightning, strong winds, hail, and heavy rain

• Occur in conditions with light winds and high moisture near the surface

In meteorological forecasts, an "isolated chance" of thunderstorms means there is about a 10 to 20 percent probability of storms occurring, indicating that any storms will be few and scattered

. In summary, isolated thunderstorms are single, small-scale storms that form in localized areas with favorable moisture and wind conditions, tend to be brief, and generally pose less widespread threat than larger storm systems
