The National Weather Service issued a special weather statement for Cobb County and other metro Atlanta counties on Monday, December 26 due to the possibility of light snow in the region.
What is in the statement?
The statement gives the following details:
“…LIGHT SNOW SHOWERS AND FLURRIES ARE POSSIBLE ALONG AND JUST
SOUTH OF THE INTERSTATE 20 CORRIDOR…
“A fast-moving low pressure system will bring the potential for
light snow to Athens, metro Atlanta and Atlanta`s southern
suburbs.
“Isolated to scattered light snow showers should start to
move into metro Atlanta between 7 PM and 9 PM and quickly spread
south and eastward. Snow showers should begin to taper off between
1 AM and 2 AM.
“A trace to a couple of hundredths of snow could
accumulate. However, you should closely monitor the forecast this
morning and early afternoon for any changes in timing or
intensity of this system.”
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.

Cobb, North Fulton, Gwinnett, Barrow, Clarke, Oconee, Oglethorpe, Carroll, Douglas, South Fulton, DeKalb, Rockdale, Walton, Newton, Morgan, Greene, Heard, Coweta, Fayette, Clayton, Henry
