With a cold blast of arctic air hitting Nebraska Sunday afternoon and extending into Monday, officials are warning of the possibility of frostbite and hypothermia.
Many areas of Nebraska saw wind chills reach 30 to 40 degrees below zero Sunday night and the National Weather Service issued warnings across the state concerning the dangerous temperatures that extending into Monday.
Many schools canceled classes Monday, on what was supposed to be the first day back from Winter vacation.
Families also are being urged to keep their animals inside as much as possible during the cold snap.
The Nebraska Humane Society says it's best to bring pets inside during periods of extreme cold like this. However, they say if pets must remain outside, it's important to make sure they have a
solid structure to protect them with hay or straw inside for insulation.
Dogs also need constant access to water, so pet owners should use heated bowls during freezing weather.
