What is the difference between “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).
In other words isolated means a few showers, scattered means the showers are likely to cover 30 to 50 percent of the affected region.
