Science / Research Lets first look at why our perception of how hot/cold air depends on humidity. Humidity and temperature are correlated. WebWhen the relative humidity of the air is high, it makes the air temperature feel much hotter than it is. Humidity is a natural part of our atmosphere, it comes from the amount of water vapor in the air. Heat Index (HI) Calculator Temperature Units: Air Temperature, T: F Relative Humidity, RH: % Heat Index Calculator Results Heat Index Chart (Apparent Temperature) Classification: Very Warm Hot Very Hot Extremely Hot A powerful storm will continue to affect the eastern third of the country with severe thunderstorms, strong winds and heavy snow.
