The heat index might rise above 100 in portions of north and central Georgia Monday, according to the National Weather Service, and Cobb County is among one of the counties listed.
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.
The NWS issued a hazardous weather outlook for Cobb County and much of the rest of north Georgia that included the possibility of isolated thunderstorms today, Sunday June 12, and a heat index above 100 starting Monday.
Here is an excerpt from the hazardous weather outlook:
