Sub-zero wind chill temperatures are expected to accompany the winter storm

The coldest air since the historic winter storm a year ago is being blown in by winds up to 30 miles per hour, bringing cold wind chill temperatures on Thursday. By Thursday afternoon, wind chill readings will be in the 10s across the region. Friday morning, many indeed Low temperatures in the 10s are possible with single-digit wind chill values, some even below zero degrees. That’s borderline Windchill Notice area, and the National Weather Service monitors. For more information on wind chill temperature and a wind chill graph, see below.

Wind chills Friday morning are expected to range from below zero to into the single digits

The combination of wind and low temperatures in winter can be deadly. The Wind Chill Index helps you determine when dangerous conditions that could lead to frostbite or hypothermia are developing by accounting for the human body’s heat loss to its surroundings in cold and windy weather.

According to the National Weather Service, the calculation uses wind speed in miles per hour and temperature in degrees Fahrenheit. For example, a temperature of -5 degrees encountered in a 20 mph wind produces a wind chill of -30 degrees (see wind chill calculation table below). This means that your body loses the same amount of heat as when the air temperature is -30 degrees without wind.

Wind chill values ​​of -25 degrees mean that frostbite can develop within 15 minutes. Frostbite is the freezing of the skin and underlying body tissue. It first affects exposed body tissues where blood flow may be restricted, such as fingers, toes, nose, and ears. To minimize frostbite, make sure all parts of the body are well covered. When frostbite begins, you will lose feeling in the affected area and the frozen tissue will appear white or pale. If you suspect frostbite, hold the frostbite close to warm skin to return blood flow and heat to the affected area.

Hypothermia is low body temperature and the most common winter weather killer. Hypothermia was a leading cause of death during the February 2021 Texas blackout. Hypothermia occurs more easily when you or your clothing are wet.

Warning signs of hypothermia include uncontrollable tremors, memory loss, disorientation, slurred speech, and drowsiness. If you suspect someone has hypothermia, seek medical attention immediately. If help is not available, the victim should be warmed slowly with warm fluids, dry clothing, and blankets.

The National Weather Service issues wind chill advisories and warnings when a deadly combination of wind and cold air threatens. To learn more about Windchill, visit: www.weather.gov/om/windchill.

When cold weather threatens, follow these survival tips:

  • Stay dry. Wet clothing causes your body to lose heat much faster. Wear waterproof insulated boots.
  • Stay covered. Wear mittens or gloves and wear a hat. Without a hat, at least half of the body heat is lost.
  • dress layered. Trapped air between loose-fitting clothing contributes to insulation.
  • stay informed Keep a portable NOAA weather radio nearby to keep you up to date with the latest forecasts and warnings. Use wind chill temperatures to guide you in the right clothing for the great outdoors. If possible, you should not be outdoors on very cold days.
