A brutally cold Sunday across Nebraska and western Iowa is expected to be followed by a mild warm-up in time for New Year’s Eve celebrations.
Dan Pydynowski, a meteorologist with AccuWeather, The World-Herald’s weather consultant, said Sunday’s dangerous wind chills of 20 to 30 degrees below zero were created by an Arctic cold front dropping down over much of the Plains. Winds of 25 mph to 30 mph caused the deep freeze, he said.
The National Weather Service in Valley reported a high temperature of 13 degrees at 3 p.m. at Eppley Airfield.
“That Arctic front came straight out of northwest Canada and the Yukon (Territories),” Pydynowski said.
The quick-hitting cold front is expected to disappear Monday, when temperatures are expected to rise into the upper 20s. The change will be caused by winds shifting to the southwest, Pydynowski said.
Western Nebraska can expect even warmer weather Monday, he said, with a high of 40 degrees predicted in the Scottsbluff area.
A weak storm system could cause a few snow flurries in eastern Nebraska and western Iowa on Tuesday, Pydynowski said. Temperatures are expected to rise again into the upper 20s, perhaps even reaching 30 degrees, he said.
“New Year’s Eve celebrations (in eastern Nebraska) can expect moderate temperatures in the upper teens, with winds about
5 to 10 mph,” he said. “The wind will bring an extra chill to the air but nothing like ... Sunday.”
Pydynowski predicted that it will be colder again on New Year’s Day and Thursday, with a high temperature of 15 both days.
Moderate temperatures with highs in the 30s are expected Friday and Saturday.
Little snow has fallen so far this season in eastern Nebraska, but Pydynowski said: “There’s a lot of winter left and a lot of time for the snow to fall.”
