The weather service also said that while heat index values will fall below advisory criteria during the night hours, heat indices in the 90s will be common during each overnight period into the upcoming weekend.
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. There is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
