Bitter cold has Nebraska in its grip.
The National Weather Service issued a wind chill advisory for much of the state as wind chills range from minus 15 to minus 30.
The extreme wind chills prompted the Omaha and Lincoln public school districts to cancel classes for today. Other districts also canceled classes. Nebraska schools closed yesterday for Martin Luther King, Jr. Day.
The weather service expects temperatures to warm throughout the week, but for today wind chills have become dangerous. NWS says exposed skin could become frostbitten within half an hour.
According to the weather service, the stiff northwesterly winds should begin to die down and shift to the south, which would allow warmer air to move into the state. Wednesday could see highs warm into the 20s and by the end of the week, temperatures might even move into the 40s
