The National Weather Service issued a heat advisory for Cobb County and much of the rest of north Georgia as the heat index is expected to soar to 105 to 110 degrees on Tuesday June 14.

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.
