The National Weather Service issued a hazardous weather outlook for  Cobb County and other counties in the region for Tuesday November 21.

Thunderstorms are expected to move across the region, and a few may become strong to severe.

What is in the statement?

The hazardous weather outlook  gives the following details:

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE…Today and Tonight…

Showers and thunderstorms will move across the area Today. A few

storms may become strong to severe with gusty winds. While

unlikely, an isolated and brief tornado cannot be ruled out for

portions of west Georgia. Southeast winds will increase into the

15-25 mph range with gusts of 30-40 mph, mainly across North GA.

.DAYS TWO THROUGH SEVEN…Wednesday through Monday…

More rounds of precipitation will move through the area Friday and

again Monday. Right now it looks like we will not have any

hazardous weather with these systems but will keep a close eye on

how they develop.

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.
