According to a hazardous weather outlook from the National Weather Service on Friday, June 30, Cobb County and much of north and central Georgia are under threat from possible thunderstorms.
The outlook includes the possibility of strong to severe storms, particularly in north Georgia.
The heat index is also expected to rise to the 100-110 degree range beginning over the weekend (see the section further down this article for an explanation of how the heat index is calculated).
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…
Thunderstorms will be possible today across north and central
Georgia, with best chances across northern Georgia. Some of these

in effect for far northern Georgia, with a Marginal Risk (1 out

Hot and humid conditions will lead to elevated heat index values
between 100-110 degrees across portions of the forecast area from
Saturday through Wednesday. If spending time outdoors, be sure to

to rest.
Additionally, isolated to scattered afternoon and evening

CDC guidelines.
What is the heat index?
The NWS defines the heat index as follows on its website:
The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This has important considerations for the human body’s comfort. When the body gets too hot, it begins to perspire or sweat to cool itself off.
