The National Weather Service issued a hazardous weather outlook for Cobb County and other parts of north and central Georgia due to two waves of thunderstorms approaching the region.

The first is expected to reach us tomorrow, Friday, March 22.  The second is forecast to arrive next Tuesday.

What is in the statement?

The statement gives the following details:

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

.DAY ONE…Today and Tonight…

No hazardous weather is expected today and tonight.

.DAYS TWO THROUGH SEVEN…Friday through Wednesday…

Widespread rainfall and isolated thunderstorms are expected in the

time. Most of the area should see rainfall totals between 1 and

2.5 inches.

Thunderstorms return the region on Tuesday as another front

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).

In other words isolated means a few showers, scattered means the showers are likely to cover 30 to 50 percent of the affected region.
