The heat index (HI) is an index that combines air temperature and relative humidity. The human body normally cools itself by perspiration, or sweating, which evaporates and carries heat away from the body. However, when the relative humidity is high, the evaporation rate is reduced. Heat is removed from the body at a lower rate, causing it to retain more heat than it would in dry air.
This evening’s weather forecast calls for a 40 percent chance of showers and thunderstorms. Some storms could be severe, with large hail, damaging winds and heavy rain in some areas. On Friday there’s a 50 percent chance of showers and thunderstorms. It will be mostly cloudy with a high near 78 degrees.
