We calculate a 'feels like temperature by taking into account the expected air temperature, relative humidity and the strength of the wind at around 5 feet (the typical height of an human face) combined with our understanding of how heat is lost from the human body during cold and windy days. Calculate the saturated vapor pressure with a formula. I had no prior knowledge on how to calculate the feel like temperature before I started to work on this template so there is likelly room for improvement. And as we heard from meteorologist Morgan Miller in an earlier episode, local weather forecasters usually know what estimates work best for their region and can combine that knowledge with their personal experience to give you the best feels like estimate.

The wind chill is how cold the air feels on your skin when factoring in the wind for any temperature at or below 50 degrees with wind speeds above 3 mph. Wind chill involves measuring the temperature as it is felt on the skin, which is determined by the air temperature and wind speed. The "feels like" (or I call the real temperature) is 110 F. The heat index combines the temperature and a measure of the relative humidity to give a better indication of how hot that temperature will actually feel. They further incorporate expected heat transfer rates across an average sized human body with an average metabolism. So, the calculator about Wind Chill Index can tell us how cold the wind is. Miami, FL: 90F, 85 percent humidity = heat index = 117F (humid, sweat it out, seek air conditioned places) = feels like Thailand. When winds howl with icy fury this winter, the AccuWeather RealFeel Temperature can help you determine how cold it really feels outside.
