The National Weather Service issued a hazardous weather outlook for Cobb County on Tuesday August 30 due to scattered thunderstorms that are expected this afternoon as a cold front heads our way. The highest coverage area for the storms are expected to be in north Georgia.

The NWS defines “cold front” as “A zone separating two air masses, of which the cooler, denser mass is advancing and replacing the warmer,” so in this case it does not mean we’re going to have cold weather this week. The temperatures during the week will be highs in the 80s and lower 90s during the day, with overnight lows in the 60s and 70s.

It means that a mass of cooler air will replace the warmer air now over the region.

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.
