The National Weather Service issued a hazardous weather outlook for Cobb County on Monday December 19, 2022 due to a rapidly approaching system expected to bring cold rain this evening and extreme temperatures later in the week.

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…

A fast-moving system is expected to bring a cold rain to the area

starting late tonight through Tuesday evening. There is a small

chance that the rain could begin as light freezing rain across the

higher elevations of northeast Georgia, by early Tuesday morning.

Impacts at this time, are expected to remain minimal and

isolated.

“.DAYS TWO THROUGH SEVEN…Tuesday through Sunday…

The main story continues to be the extremely cold temperatures

that are expected to spill across Georgia, Thursday night into

Friday morning. High temperatures may struggle to get out of the

20s and lower 30s on Friday across much of the area, with lows

bottoming out between 5 and 20 degrees Friday night. Factor in the

gusty winds that will occur with this powerful storm system, and

wind chill values could get as cold as 5 to 15 below zero for

parts of north Georgia.

“Across mainly north and west Georgia, the potential for some

wintry precipitation exists as well, as rain quickly changes to

snow before ending late Thursday night into Friday morning. Any

accumulations are expected to minimal, generally less than an

inch, but the concern for icy conditions, even due to residual

water on the roads, will increase as temperatures drop well below

freezing by Friday morning.”

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.
