The wind chill also isn't a meteorologist's best guess at what the air outside feels like, because it's based on the actual measured temperature and wind speed. There's an equation to calculate ...
Wind chill index values for a range of temperatures and wind speeds, from the standard wind chill formula for Environment Canada. Wind chill (popularly wind chill factor) is the sensation of cold produced by the wind for a given ambient air temperature on exposed skin as the air motion accelerates the rate of heat transfer from the body to the surrounding atmosphere.

The Australian formula includes the important factor of humidity and is somewhat more involved than the simpler North American wind chill model. The North American formula was designed to be applied at low temperatures (as low as −46 °C or −50 °F) when humidity levels are also low.
The wind chill chart. The weather service began to include wind chill in their forecasts in the early 1970s, several decades after Antarctic explorers first published research about it in the late ...
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
The combination of high speed winds and freezing temperatures can be deadly. What to know about staying warm as cold fronts move through Tennessee.
