Detailed Forecast and Heat Index Explanation
The anticipated high of 94°F, coupled with significant humidity, will result in a heat index exceeding 100°F across much of the affected area. The heat index, also known as the apparent temperature, is a measure of how hot it feels to the human body when relative humidity is combined with the air temperature. It provides a more accurate representation of the perceived heat than the actual air temperature alone. High humidity reduces the body’s ability to cool itself through perspiration, making it feel hotter.
According to the NWS, the heat index is calculated using a complex formula that takes into account both air temperature and relative humidity. The higher the humidity, the less effectively the body can cool itself, leading to a higher heat index value. When the heat index reaches dangerous levels, it is crucial to take precautions to prevent heat-related illnesses.
