WATERLOO (KWWL) -- Cold air will move into Iowa Tuesday on breezy north winds of 10-20 mph. Temperatures will be steady or falling and we could see some flurries. Despite keeping clouds and some flurries, that cold north wind will bring in some very cold air and we will drop to below zero in many areas tonight. Lows will range from 2 above to -7 with wind chills around -15.
Frigid conditions are not only uncomfortable; they can also be dangerous.
The skin damage caused by frostbite results in a loss of feeling and a grayish color in affected areas. It most often affects exposed skin and extremities such as the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the skin, causing scarring, and severe cases can lead to amputation. Signs of frostbite include a white or grayish-yellow skin area, skin that feels unusually firm or waxy, or numbness. A person is often unaware of frostbite until someone else points it out because the frozen tissues are numb.
If you must be outside for any length of time, make sure you check yourself, others around you, and your children for these signs. If your skin shows these signs of freezing, go into a warm place immediately. Warm up frozen/chilled skin by pressing against normal temperature skin. Seek medical attention if skin does not quickly return to normal color or pain occurs and continues.
