Iowa
Iowa will be the coldest state in the US. Maps show how cold it’ll be.
What is the polar vortex? How it can impact snow, freezes in the U.S.
The polar vortex is a large area of circulating cold air above the North Pole. Strong winds keep it contained, but when it weakens, it can wobble and stretch.
Temperatures across Iowa are forecast to plunge to the coldest in the Lower 48, dipping well below zero as a surge of Arctic air sweeps in.
The broader weather pattern will stay active and winter-like through the end of the week and into the weekend. A recent stratospheric disturbance weakened the polar vortex, allowing frigid Arctic air to spill into the U.S. and shift the jet stream, bringing snow and wintry precipitation to several regions.
While the heaviest snow will target the Rockies and High Plains on Dec. 3, Iowa will primarily feel the effects of a strong cold front and fast-moving clipper systems sweeping through the Great Lakes and Midwest.
“An active winter-like pattern will continue to bring the threat of winter weather to multiple areas of the country through the end of the week and into the weekend,” the Climate Prediction Center said.
When is the coldest air expected in Iowa?
Dangerous cold will dominate the forecast through Thursday, Dec. 4. Record-breaking lows are likely early Thursday, and even daytime highs will struggle to climb out of the single digits and teens. Winds will ease overnight, but the extreme cold will persist.
By Friday, Dec. 5, temperatures moderate slightly, but the pattern remains active into the weekend.
When will temperatures warm up in Iowa?
After the deep freeze, a gradual warm-up arrives Friday, Dec. 5, though temperatures will still run below normal.
The weekend and early next week look unsettled, with a series of disturbances tracking through the Midwest. While confidence in timing and amounts remains low, light snow chances will return periodically. Anyone with travel plans should monitor updates closely, as even light snow combined with cold conditions could impact roads.
Is snow expected in Iowa?
Light snow showers are possible today, Dec. 3, along the trailing cold front.
Additional chances for snow are possible on Thursday, Dec. 4, as another clipper system passes through. Accumulations in Iowa should remain light, but the bitter cold will dominate the story, with temperatures running well below normal for early December.
Several weak systems will ripple through the region, bringing occasional chances for light snow. While significant accumulations appear unlikely, even minor snowfall could cause hazards as low temperatures keep roads slick.
“Anyone with travel plans this weekend should monitor the latest forecast updates, because while at this time the probability of a significant snowfall event is low, even lighter accumulations could still impact travel conditions at times,” the National Weather Service office in Des Moines wrote.

Rick Barnes reacts to Tennessee’s win over Iowa State
No. 6 seed Tennessee (25-11) defeated No. 2 seed Iowa State (29-8), 76-62, on Friday in the NCAA Tournament Sweet 16 at United Center in Chicago, Illinois.
The Vols advanced to their third consecutive Elite Eight under 11th-year head coach Rick Barnes.
“One, very humbled by it,” Barnes said. “Certainly proud of our basketball team. They worked really hard. Defensively, I thought we knew we would have to have a great effort defensively. Certainly Iowa State, outstanding. T.J. (Otzelberger), outstanding program, coach.
“This time of year is always tough when you lose a key guy like they did, and that’s part of the tournament. That’s the tough part about it, but just really proud of our guys and the effort they made and against a team that they play as hard as any team we played all year. The start of the game, I don’t think we’ve seen anything like that all year, and we were able to withstand it. Again, just really proud of the effort from our entire team. Everybody had a hand in us winning this game.”

Tennessee basketball vs Iowa State Sweet 16 tipoff time changed for later start
CHICAGO − Tennessee basketball’s Men’s NCAA Tournament game against Iowa State will start a little later than planned.
The Sweet 16 game between the No. 6 Vols (24-11) and No. 2 Cyclones (29-7) will now tipoff at 10:25 p.m. ET at the United Center on TBS.
The game was originally scheduled for 10:10 p.m. before the 15-minute delay. There is also the standard 30-minute break in between tournament games. Tennessee and Iowa State won’t begin until 30 minutes after the end of No. 1 Michigan (33-3) and No. 4 Alabama (29-5).
Iowa State forward Joshua Jefferson status
Iowa State’s star forward Joshua Jefferson is questionable against Tennessee basketball according to the NCAA player availability report released at 6:32 p.m.
Jefferson sprained his ankle in the opening minutes of Iowa State’s first-round game against Tennessee State. He sat for the remainder of the game and missed the Cyclones’ win over Kentucky on March 22. Iowa State didn’t need the All-Big 12 forward as it generated 20 Wildcat turnovers in its 19-point victory.

Two Iowans sentenced to prison for creating child pornography
Child abuse: What signs to watch for if you suspect it
Child abuse includes physical, sexual, emotional and medical abuse, as well as neglect. Learn about signs, risk factors, how to get help.
Wochit, Wochit
Two Iowans will spend decades in federal prison after pleading guilty to separate child exploitation offenses.
Martin Menjivar, 59, of Iowa City, was sentenced Thursday, March 26, to 42 years in prison after pleading guilty to sexual exploitation of a child and child pornography possession. It comes days after Pry’Shayn Mosley, 21, of Fort Dodge was sentenced to 25 years for exploitation and receipt of child pornography.
Iowa City man picked up children from school, abused them
Menjivar, a citizen of Honduras, was charged in May 2025. In court filings, prosecutors say Menjivar was entrusted to pick up children, some as young as 5, from their elementary school and bring them to his wife’s home for after-school babysitting. In at least two cases, Mejivar used that access to get children alone and touch them inappropriately, recording the interaction on video.
Investigators reportedly found dozens of illicit images and videos on Menjivar’s electronic devices. Menjivar also previously worked as a school photographer in Honduras, and investigators found he had hundreds of photos from his former employment that focused on children’s clothed genitals.
“Defendant’s horrific actions of creating and collecting child pornography show violence against young, vulnerable children and a severe danger to the community,” prosecutors wrote in presentence filings.
Menjivar also has been charged in Johnson County with second-degree sexual abuse against two different children, apparently in relation to the same conduct. That case remains pending, with a plea hearing scheduled in May.
Fort Dodge man gets 25 years for enticing children
Mosley, who was sentenced March 23, was charged in January 2025. Prosecutors alleged that in 2022, he enticed two minors to engage in sexually explicit conduct, photographed or recorded it, and distributed the resulting pornography to others, including additional children.
In addition, during a warrant search that located drugs, guns and electronic devices containing child pornography, Mosley tried to get a juvenile at the scene to conceal drugs from the investigators.
Mosley pleaded guilty to sexual exploitation and receiving child pornography. Additional drug, pornography and exploitation charges were dismissed as part of a plea deal.
Menjivar was prosecuted by the U.S. Attorney’s Office for the Southern District of Iowa, while Mosley’s case was handled by the U.S. Attorney’s Office for the Northern District of Iowa. Attorneys for Menjivar and Mosley did not immediately return messages Thursday seeking comment.
