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.
You can also approximate the wind chill with a little mental math: If the temperature is minus 13 degrees and the wind speed is 15 mph, the wind chill will be somewhere between minus 32 and minus 39.
Wind chill makes it feel much colder than it really is, so it's been described as a "feels-like" number. If the temperature is 0 degrees and the wind is blowing at 15 mph, the wind chill is 19 ...
A cold weather advisory (formerly known as a wind chill advisory until October 2024) [1] is a hazardous weather statement issued by Weather Forecast Offices (WFO) of the National Weather Service (NWS) in the United States to alert the public that temperatures or wind chills are forecast to reach values low enough that it poses a threat to human health and life if adequate protection is not ...
Apparent temperature, also known as "feels like", [1] [2] is the temperature equivalent perceived by humans, caused by the combined effects of air temperature, relative humidity and wind speed. The measure is most commonly applied to the perceived outdoor temperature.
In the United States an extreme cold warning was an experimental weather warning issued by the National Weather Service in North Dakota, South Dakota, and Minnesota. [5] The warning was issued if the temperature fell to −35 °F (−37 °C) or colder with a wind of less than 5 mph (8 km/h; 2 m/s). [6]
Chicago, Illinois, reached −21 °F (−29.4 °C) [23] with wind chills of around −55 °F (−48.3 °C), [24] the coldest day of the 1990s in Chicago by far. [25] Almost all primary and secondary schools in Chicago were closed that day. Richard Daley, then mayor of Chicago advised residents not to go outside if they don't have to.
