Forecasters have extended a heat advisory for the metro-east that was expected to end Wednesday evening as heat-index temperatures are expected to reach 106 degrees on Thursday.
“The combination of hot temperatures and high humidity will continue through Thursday afternoon, leading to an increased risk of heat-related stress and illness,” the advisory states. “This is especially true since the heat and humidity has persisted since Sunday and is expected to continue for the fifth day today.”
There is a 30 percent chance for showers in the early evening hours of Thursday, with a temperatures dropping to a low around 75 degrees.
The heat index, what hot weather feels like to the body, takes humidity into account in addition to temperature. When the air is more humid, it makes it harder for sweat to evaporate, which means that people’s bodies are less effective at cooling down.
