An arctic airmass will remain in place and northwest winds will continue at 15 to 25 mph with a few higher gusts this evening. Temperatures are expected to plummet even colder tonight with early morning lows ranging from around 5 below near the Missouri River, to near 20 below in the Highway 14 corridor. These frigid temperatures coupled with the wind will result in dangerously cold wind chill values of -20 to -35 this evening and tonight. Wind Chill advisories remain in effect across much of the region. Stay safe and be prepared for these bitterly cold temperatures and dangerous wind chills. Be sure to also protect animals and other outdoor interests sensitive to the cold temperatures. Temperatures will begin to modify and warm during the day Friday with afternoon high temperatures reaching the teens to 20s above zero.
Watch for signs of frostbite or hypothermia when outdoors during extreme cold weather.
Frostbite is a severe reaction to cold exposure that can permanently damage its victims. A loss of feeling and a white or pale appearance in fingers, toes, or nose and ear lobes are symptoms of frostbite. In fact, research (P.Tikuisis, 2004) has shown that uncovered fingers can freeze up to 8 times faster than a human cheek, and the nose can freeze 3 times faster. This illustrates the importance of keeping fingers and parts of your face (ear lobes, nose) well covered in extreme cold weather.
Hypothermia is a condition brought on when the body temperature drops to less than 95 deg F. Symptoms of hypothermia include uncontrollable shivering, slow speech, memory lapses, frequent stumbling, drowsiness, and exhaustion.
If frostbite or hypothermia is suspected, begin warming the person slowly and seek immediate medical assistance. Warm the person's trunk first. Use your own body heat to help. Arms and legs should be warmed last because stimulation of the limbs can drive cold blood toward the heart and lead to heart failure. Put the person in dry clothing and wrap their entire body in a blanket.
Never give a frostbite or hypothermia victim something with caffeine in it (like coffee or tea) or alcohol. Caffeine, a stimulant, can cause the heart to beat faster and hasten the effects the cold has on the body. Alcohol, a depressant, can slow the heart and also hasten the ill effects of cold body temperatures.
