What is wind chill?
The National Weather Service says the wind chill temperature is how cold people and animals feel when outside. Wind chill is based on the rate of heat loss from exposed skin caused by wind and cold.
“As the wind increases, it draws heat from the body, driving down skin temperature and eventually the internal body temperature. Therefore, the wind makes it feel much colder. If the temperature is 0 degrees and the wind is blowing at 15 mph, the wind chill is minus 19 degrees. At this wind chill temperature, exposed skin can freeze in 30 minutes,” the NWS said.
The NWS has issued a wind chill watch for the Denver metro area, Front Range, and Eastern Plains for wind chills as low as 50 degrees below zero from Wednesday evening into Friday morning.
