What is wind chill?
Wind chill is a figure that takes into account the wind speed and the actual air temperature.
There is a mathematical formula for determining wind cooling. Effective in 2001, the wind formula in mph and Fahrenheit temperatures is: Wind cooling temperature = 35.74 + 0.6215T – 35.75V (** 0.16) + 0.4275TV (** 0.16).
A simpler method for determining the wind chill temperature is by referring to the NWS Wind Chill Chart.
The wind cooler is how cold it actually feels on your skin when the wind is counted, explained Meteorologist Ashley Novak of the National Weather Service Office in Wilmington, Ohio.

What is polar vortex?
The polar vortex is a large area with low pressure and cold air around both of the Earth's poles, according to the National Weather Service. Many times in the winter in the northern hemisphere, the polar vortex will expand and cause large outbreaks of arctic air in the United States.
While many regions of the United States are hit harder than Louisville, they become cold temperatures we feel caused by polar whirl.
"The extremely cold temperatures we want to feel are due to the polar whirl, Said the NWS Louisville meteorologist Evan Webb.
National Weather Service said there is no reason to be alarmed when you hear of polar whirl, but you should be prepared for colder temperatures.
