Understanding 'Feels-Like' Temperatures During Winter Storms

During winter storms, the combination of cold air and strong winds can make the environment feel much colder than the actual air temperature. This perceived temperature is known as the "feels-like" temperature or wind chill.

What Is Wind Chill?

Wind chill is the apparent temperature that describes how cold it feels on human skin due to the combined effects of wind and cold temperatures. As wind increases, it removes heat from the body more rapidly, causing skin temperature to drop. This accelerated heat loss can lead to frostbite and hypothermia if proper precautions aren't taken.

How Is Wind Chill Calculated?

The National Weather Service (NWS) calculates wind chill using a formula that factors in wind speed and air temperature. For example, at an air temperature of 0°F (-18°C) with a wind speed of 15 mph, the wind chill temperature would be -19°F (-28°C). Under these conditions, exposed skin can freeze in 30 minutes.

Why Is Wind Chill Important?

Understanding wind chill is crucial because it helps assess the risk of frostbite and hypothermia. The NWS issues wind chill warnings and advisories based on the apparent temperature to inform the public of potential dangers. For instance, a wind chill warning is issued when wind chills are expected to be life-threatening. (weather.gov)

How to Stay Safe During Extreme Cold

  • Dress Appropriately: Wear multiple layers of clothing to trap body heat.
  • Protect Exposed Skin: Use hats, gloves, scarves, and face masks to shield skin from the cold.
  • Limit Time Outdoors: Stay inside during extreme cold periods, especially when wind chills are dangerously low.
  • Stay Informed: Monitor local weather forecasts and heed any wind chill warnings or advisories issued by the NWS.

Conclusion

Wind chill significantly impacts how cold it feels during winter storms, affecting the risk of cold-related illnesses. By understanding wind chill and taking appropriate precautions, you can stay safe during extreme cold events.
