Nebraskans are preparing to deal with the coldest air of the season.
Temperatures will fall as low as 15-to-20 degrees below zero across Nebraska Sunday night, and Monday's high temperatures could remain below zero in many places.
Wind chills of 30-to-40 degrees below zero are expected across Nebraska Sunday night.
Officials are warning that frostbite and hypothermia are possible if people aren't properly bundled up.
The weather is also affecting flights in and out of Eppley Airfield in Omaha and the Lincoln Airport. Flights to and from Chicago O'Hare International Airport are cancelled from both Lincoln and Omaha.
Other cancellations are also listed on both airport's websites, but it's unclear if they're because of weather.
Representatives from both airports told 10/11 News if you're traveling Sunday or Monday, be sure to keep a close eye on your flight to make sure it's leaving on time.

Monday is the first day students return to class after a two week winter break.
The Railyard announced on it's Facebook page that the ice rink is closed on Sunday, "Those arctic winds are showing us seasoned winter folk what cold REALLY feels like. Since frostbite isn't fun for anyone, we're letting our staff stay warm at home today and closing up the rink. Sorry friends!"
The Facebook post added, "We will likely be closed again tomorrow, [Monday] but please check back on The Railyard Lincoln page for updates."
