Night wind chills of minus 10 degrees to minus 20 degrees are forecast for Tuesday through Thursday by the National Weather Service in northern Indiana.
All of northeast Indiana and northwest Ohio are forecast to get extremely cold temperatures at night over the next few days.
A winter storm is expected to reach the region this weekend, the weather service said.
What does wind chill mean?
Wind chill is based on the rate of heat loss from exposed skin caused by the combined effects of wind and cold. As the wind increases, heat is carried away from the body at an accelerated rate, driving down the body temperature. This temperature is the reading the body “feels” given the combination of wind and air temperature. At wind speeds of 4 mph or less, the wind chill temperature is the same as the air temperature.
