What is meant by “isolated” and “scattered”?
The NWS defines “isolated” as follows:
A National Weather Service convective precipitation descriptor for a 10 percent chance of measurable precipitation (0.01 inch). Isolated is used interchangeably with few.
“Scattered” has the following definition:
When used to describe precipitation (for example: “scattered showers”) – Area coverage of convective weather affecting 30 percent to 50 percent of a forecast zone (s).
Isolated thunderstorms and scattered thunderstorms are two terms used to describe different distributions of thunderstorm activity within a particular area. The main difference lies in the extent of coverage and how the thunderstorms are spatially distributed:
- Isolated Thunderstorms:
· Isolated thunderstorms are relatively rare occurrences that happen sporadically and are generally confined to a limited area.
· These thunderstorms are often characterized by being few and far between, with significant gaps between individual storm cells.
· Typically, isolated thunderstorms cover less than 20% of the forecast area.
· Despite their isolated nature, these storms can still be intense and may produce heavy rain, lightning, gusty winds, and possibly hail.
- Scattered Thunderstorms:
· Scattered thunderstorms are more widespread than isolated thunderstorms and cover a larger portion of the forecast area.
· In a scattered thunderstorm scenario, numerous individual thunderstorms develop, but they are not continuous or widespread enough to be classified as a “line” or “cluster” of storms.
· Scattered thunderstorms generally cover between 30% to 50% of the forecast area.
· Although scattered thunderstorms are more widespread, they still leave considerable gaps between storm cells, and not everyone within the forecast area will necessarily experience a thunderstorm.
In summary, isolated thunderstorms are fewer in number and more localized, covering a smaller area with significant gaps between storms, while scattered thunderstorms are more widespread, covering a larger area with numerous individual storms occurring somewhat randomly across the forecast area.
