(AP Photo/Kiichiro Sato)2026-01-21T14:47:41Z WASHINGTON (AP) Warm Arctic waters and cold continental land are combining to stretch the dreaded polar vortex in a way that will send much of the United States a devastating dose of winter weather later this week with swaths of painful subzero temperatures, heavy snow and powerline-toppling ice.Meteorologists said the eastern two-thirds of the nation is threatened with a winter storm that could rival the damage of a major hurricane and has some origins in an Arctic that is warming from climate change. They warn that the frigid weather is likely to stick around through the rest of January and into early February, meaning the snow and ice that accumulates will take a long time to melt. Forecasts have the storm, expected to hit starting Friday, stretching from New Mexico to New England and across the Deep South. About 230 million people face temperatures of 20 degrees (-7 degrees Celsius) or colder and around 150 million are likely to be hit by snow and ice, with many Americans getting both, according to the National Weather Service. I think people are underestimating just how bad its going to be, said former National Oceanic and Atmospheric Administration chief scientist Ryan Maue, now a private meteorologist. The polar vortex, a patch of bitterly cold air that often stays penned up in northern Canada and Alaska, is being elongated by a wave in the upper atmosphere that goes back to a relatively ice-free part of the Arctic and snow-buried Siberia. As the bone-chilling temperatures sweep through the U.S., theyll meet with moisture from off California and the Gulf of Mexico to set up crippling ice and snow in many areas.

Share Share Facebook Copy Link copied Print Email X LinkedIn Bluesky Flipboard Pinterest Reddit Read More Origins of the system in a warming ArcticThe origins of the system begin in the Arctic, where relatively warmer temperatures add energy to the polar vortex and help push its cold air south. The atmosphere is aligned perfectly that the pattern is locked into this warm Arctic, cold continent, Maue said. And its not just here for us in North America, but the landmass of Eastern Europe to Siberia is also exceptionally cold. The whole hemisphere has gone into the deep freeze.As far back as October 2025, changes in the Arctic and low sea ice were setting up conditions for the kind of stretched polar vortex that brings severe winter weather to the U.S., said winter weather expert Judah Cohen, an MIT research scientist. Heavy Siberian snowfall added to the push-and-pull of weather that warps the shape of the normally mostly circular air pattern. Those conditions kind of loaded the dice a bit for a stretching of the polar vortex, he said.Cohen co-authored a July 2025 study that found more stretched polar vortex events linked to severe winter weather bursts in the central and eastern U.S. over the past decade. Cohen said part of the reason is that dramatically low sea ice in the Barents and Kara seas in the Arctic helps set up a pattern of waves that end up causing U.S. cold bursts. A warmer Arctic is causing sea ice in that region to shrink faster than other places, studies have found. Arctic sea ice is at a record low extent for this time of year, according to the National Snow and Ice Data Center.

Temperatures in the North and Midwest will get about as cold as possible, even down to minus 25 or 30 degrees Fahrenheit (minus 32 to minus 34 degrees Celsius), Maue said. The average low temperature for the Lower 48 states will dance around 11 or 12 degrees (minus 12 to minus 11 degrees Celsius) on Saturday, Sunday and Monday, Maue said.Two Great Lakes Erie and Ontario may freeze up, which would at least reduce the famed lake-effect snow a bit, Maue said.National Weather Service meteorologist Zack Taylor of the national Weather Prediction Center said most areas east of the Rockies will be impacted by the bitter cold, snow or ice. Treacherous freezing rain could stretch from the southern plains through the mid-South and into the Carolinas, he said. Were looking at the potential for impactful ice accumulation. So the kind of ice accumulation that could cause significant or widespread power outages or potentially significant tree damage, he said. And if you dont get ice, you could get another significant swath of heavy snow, Taylor said. He said it was too early to predict how many inches will fall, but significant snowfall accumulations could hit the Ozarks region, Tennessee and Ohio valleys, the central Appalachians, and then into the mid-Atlantic, and perhaps into the portions of the northeast.Maue said in the mid-Atlantic around the nations capital, theres a possibility that you can get two blizzards on top of each other in the next 14 days.___The Associated Press climate and environmental coverage receives financial support from multiple private foundations.

Former Uvalde school district police officer Adrian Gonzales, left, talks to his defense attorney Nico LaHood during a break on the 10th day of his trial at Nueces County Courthouse in Corpus Christi, Texas, Tuesday, Jan. 20, 2026. (Sam Owens/The San Antonio Express-News via AP, Pool)2026-01-21T05:01:50Z CORPUS CHRISTI, Texas (AP) A Texas prosecutor urged a jury Wednesday to convict one of the first police officers on the scene of the deadly Robb Elementary School attack in Uvalde and send a message that law enforcement must fulfill their duty to protect when a gunman threatens children.Adrian Gonzales, a former Uvalde schools officer, is the first officer to stand trial over the hesitant police response to the 2022 massacre, when a teenage gunman killed 19 fourth-graders and two teachers in one of the deadliest school shootings in U.S. history.The trial is a rare case of a police officer charged with failing to stop a criminal act to protect lives.Gonzales, 52, sat at the defense table during closing arguments as special prosecutor Bill Turner told jurors the 10-year police veteran had a duty to act even if it meant entering the building alone. Sitting behind Gonzales in the courtroom were family members of several of the victims. Some cried when the names of the children killed and wounded that day were read out loud.Were expected to act differently when talking about a child that cant defend themselves, Turner said. If you have a duty to act, you cant stand by while a child is in imminent danger. As jurors, Turner said, their verdict will set the bar over whether its appropriate to stand outside, hearing 100 shots, while children are being slaughtered. Stay up to date with the news and the best of AP by following our WhatsApp channel. Follow on The jury began its deliberations after listening to a little over two hours of closing statements from prosecutors and defense lawyers. Jason Goss, an attorney for Gonzales, began his closing statements by telling jurors his client was not responsible for the attack.The monster that hurt those kids is dead, Goss said. It is one of the worst things that ever happened.Goss said a conviction would tell police they have to be perfect when responding to a crisis and could make them even more hesitant in the future.Gonzales has pleaded not guilty to 29 counts of child abandonment or endangerment for the 19 students killed and 10 others who were wounded. Gonzales faces up to two years in prison if convicted. Trial is in its third weekGonzales did not take the stand in his own defense. He has insisted he didnt freeze in the chaotic early moments and never saw the gunman, and his lawyers argue that three officers on the other side of the school saw the gunman still outside and didnt fire a shot.Body camera footage shows Gonzales being among the first group of officers to enter a shadowy and smoky hallway trying to reach the killer in a classroom.Contrary to the portrayal of a reluctant officer officer, Gonzales risked his life when he went into a hallway of death where others were unwilling to go in the early moments, his lawyers said.They are trying to feed you a coward sandwich and telling you Adrian is the one who gave it to you, defense attorney Nico LaHood told jurors.Prosecutors called 36 witnesses over nine days in a trial that began Jan. 5. Gonzales attorneys presented just two witnesses, starting with a woman who worked across the street from the school and who told jurors she saw the shooter ducking between cars and trying to stay out of view testimony that could reinforce Gonzales claims that he never saw the gunman.Jurors heard emotional testimony from teachers who recounted the terrifying moments when the 18-year-old gunman entered the school. Prosecutors have presented graphic photos from inside the classrooms and questioned officers who described the chaos of the response. Case moved out of Uvalde to get a fair trialThe trial was moved hundreds of miles to Corpus Christi after defense attorneys argued Gonzales could not receive a fair trial in Uvalde. Still, some victims families have made the long drive to watch the proceedings.Early in the trial, the sister of one of the teachers killed that day was removed from the courtroom after an angry outburst following one officers testimony.Prosecutors allege Gonzales, who had led an active shooter response training course two months before the shooting, abandoned his training and did not try to stop gunman Salvador Ramos before he entered the school. Teacher Arnulfo Reyes described seeing a black shadow with a gun enter the room before he was shot and all 11 of his students were killed. Other teachers described students, some as young as second grade, grabbing safety scissors to attack the gunman if he came into their room.Teachers and children followed their school shooting training, Uvalde County District Attorney Christina Mitchell told jurors.Were not going to continue to teach children to rehearse their own death and not hold (police) to the training thats mandated by state law, Mitchell said.Gonzales was one of 376 federal, state and local officers swarmed to the school as the attack unfolded. It would take more than an hour for a tactical team to breach a classroom and kill the gunman. Only Gonzales and former Uvalde schools police chief Pete Arredondo have been criminally charged for the delayed response. Arredondo was indicted on similar charges on the same day as Gonzales in 2024, but his trial has not yet been set.___Vertuno reported from Austin, Texas.

ADDS IDENTIFICATION: Teyana Gibson Brown, second from right, wife of Garrison Gibson, reacts after a federal immigration officer used a battering ram to break down a door before arresting Garrison Gibson, Sunday, Jan. 11, 2026, in Minneapolis. (AP Photo/John Locher)2026-01-21T21:26:45Z WASHINGTON (AP) Federal immigration officers are asserting sweeping power to forcibly enter peoples homes without a judges warrant, according to an internal Immigration and Customs Enforcement memo obtained by The Associated Press, marking a sharp reversal of longstanding guidance meant to respect constitutional limits on government searches.The memo authorizes ICE officers to use force to enter a residence based solely on a more narrow administrative warrant to arrest someone with a final order of removal, a move that advocates say collides with Fourth Amendment protections and upends years of advice given to immigrant communities.The shift comes as the Trump administration dramatically expands immigration arrests nationwide, deploying thousands of officers under a mass deportation campaign that is already reshaping enforcement tactics in cities such as Minneapolis. For years, immigrant advocates, legal aid groups and local governments have urged people not to open their doors to immigration agents unless they are shown a warrant signed by a judge. That guidance is rooted in Supreme Court rulings that generally prohibit law enforcement from entering a home without judicial approval. The ICE directive directly undercuts that advice at a time when arrests are accelerating under the administrations immigration crackdown. The memo itself has not been widely shared within the agency, according to a whistleblower complaint, but its contents have been used to train new ICE officers who are being deployed into cities and towns to implement the presidents immigration crackdown. New ICE hires and those still in training are being told to follow the memos guidance instead of written training materials that actually contradict the memo, according to the whistleblower disclosure. It is unclear how broadly the directive has been applied in immigration enforcement operations. The Associated Press witnessed ICE officers ramming through the front door of the home of a Liberian man in Minneapolis on Jan. 11 with only an administrative warrant, wearing heavy tactical gear and with their rifles drawn. The change is almost certain to meet legal challenges and stiff criticism from advocacy groups and immigrant-friendly state and local governments that have spent years successfully urging people not to open their doors unless ICE shows them a warrant signed by a judge.The Associated Press obtained the memo and whistleblower complaint from an official in Congress, who shared it on condition of anonymity to discuss sensitive documents. The AP verified the authenticity of the accounts in the complaint.The memo, signed by the acting director of ICE, Todd Lyons, and dated May 12, 2025, says: Although the U.S. Department of Homeland Security (DHS) has not historically relied on administrative warrants alone to arrest aliens subject to final orders of removal in their place of residence, the DHS Office of the General Counsel has recently determined that the U.S. Constitution, the Immigration and Nationality Act, and the immigration regulations do not prohibit relying on administrative warrants for this purpose. The memo does not detail how that determination was made nor what its legal repercussions might be. When asked about the memo, Homeland Security spokeswoman Tricia McLaughlin said in an emailed statement to the AP that everyone the department serves with an administrative warrant has already had full due process and a final order of removal.She said the officers issuing those warrants have also found probable cause for the persons arrest. She said the Supreme Court and Congress have recognized the propriety of administrative warrants in cases of immigration enforcement, without elaborating. McLaughlin did not respond to questions about whether ICE officers entered a persons home since the memo was issued relying solely on an administrative warrant and if so, how often. Recent arrests shine a light on tacticsWhistleblower Aid, a non-profit legal organization that assists workers exposing wrongdoings, said in the whistleblower complaint obtained by The Associated Press that it represents two anonymous U.S. government officials disclosing a secretive - and seemingly unconstitutional - policy directive.A wave of recent high-profile arrests, many unfolding at private homes and businesses and captured on video, has shined a spotlight on immigration arrest tactics, including officers use of proper warrants.Most immigration arrests are carried out under administrative warrants, internal documents issued by immigration authorities that authorize the arrest of a specific individual but do not permit officers to forcibly enter private homes or other non-public spaces without consent. Only warrants signed by judges carry that authority.All law enforcement operations including those conducted by ICE and Customs and Border Protection are governed by the Fourth Amendment of the Constitution, which protects all people in the country from unreasonable searches and seizures. People can legally refuse federal immigration agents entry into private property if the agents only have an administrative warrant, with some limited exceptions.Federal agents this month rammed the door of the Minneapolis home of a Liberian man with a deportation order from 2023, who was then arrested. Documents reviewed by The AP revealed that the agents only had an administrative warrant meaning there was no judge who authorized the raid on private property.Memo shown to select officialsThe memo says ICE officers can forcibly enter homes and arrest immigrants using just a signed administrative warrant known as an I-205 if they have a final order of removal issued by an immigration judge, the Board of Immigration Appeals or a district judge or magistrate judge.The memo says officers must first knock on the door and share who they are and why theyre at the residence. Theyre limited in the hours they can go into the home after 6 a.m. and before 10 p.m. The people inside must be given a reasonable chance to act lawfully. But if that doesnt work, the memo says, they can use force to go in.Should the alien refuse admittance, ICE officers and agents should use only a necessary and reasonable amount of force to enter the aliens residence, following proper notification of the officer or agents authority and intent to enter, the memo reads.The memo is addressed to all ICE personnel. But it has been shown only to select DHS officials who then shared it with some employees who were told to read it and return it, Whistleblower Aid wrote in the disclosure.One of the two whistleblowers was allowed to view the memo only in the presence of a supervisor and then had to give it back. That person was not allowed to take notes. A whistleblower was able to access the document and lawfully disclose to Congress, Whistleblower Aid said.Although the memo was issued in May, David Kligerman, senior vice president and special counsel at Whistleblower Aid, said it took time for its clients to find a safe and legal path to disclose it to lawmakers and the American people.ICE officers are told to rely solely on administrative warrants, memo saysICE has been rapidly hiring thousands of new deportation officers to carry out the presidents mass deportation agenda. Theyre trained at the Federal Law Enforcement Training Center in Brunswick, Georgia.During a visit there by The Associated Press in August, ICE officials said repeatedly that new officers were being trained to follow the Fourth Amendment.But according to the whistleblowers account, newly hired ICE officers are being told they can rely solely on administrative warrants to enter homes to make arrests even though that conflicts with written Homeland Security training materials.ICE officers often wait for hours for the person theyre hoping to arrest to come outside so they can make the arrest on the sidewalk or at the persons work public places where they are allowed to operate without the risk of infringing on the persons Fourth Amendment rights.Whistleblower Aid called the new policy a complete break from the law and said it undercuts the Fourth Amendment and the rights it protects.

(Andriy Andriyenko/Ukraine's 65th Mechanized Brigade via AP)2026-01-21T14:26:49Z KYIV, Ukraine (AP) About 4,000 buildings in Kyiv lacked heat Wednesday and nearly 60% of the Ukrainian capital was without power, Ukraines President Volodymyr Zelenskyy said, after days of Russian bombardment of Ukraines power grid and as U.S. President Donald Trump prepared to hold talks with the Ukrainian leader.Trumps delegatesalso were expected in Moscow later this week for talks with Russian President Vladimir Putin.With temperatures falling as low as minus 20 C (minus 4 F) in Kyiv, Ukraine is seeing one of the coldest winters in years, deepening the hardship of Ukrainians almost four years after Russia launched a full-scale invasion.A yearlong push by the Trump administration to stop the fighting hasnt yielded any breakthrough, despite the American president issuing a series of deadlines, though efforts were set to continue. Trump said at the World Economic Forum in Davos, Switzerland that he would meet Thursday with Zelenskyy.I want to stop it, Trump said of the fighting. Its a horrible war.U.S. special envoy Steve Witkoff told The Associated Press on Wednesday that he plans to discuss peace proposals with Putin as well as hold talks with a Ukrainian delegation. We need a peace, Witkoff said at Davos.Putin confirmed late on Wednesday that Witkoff and Trumps son-in-law Jared Kushner are expected in Moscow on Thursday for talks. The Russian leader said that Moscow and Washington, among other things, are discussing the possibility of using Russian assets frozen in the U.S. for rebuilding territories damaged by the hostilities after a peace agreement is reached. But with a dispute over Greenlands future largely eclipsing other transatlantic issues at Davos, discussions about Ukraines defense looked likely to be sidelined.Zelenskyy said last week his envoys would try to finalize with U.S. officials documents for a proposed peace settlement that relate to postwar security guarantees and economic recovery. He added that the U.S. and Ukraine could sign the documents in Davos this week, but on Tuesday he said he wouldnt be traveling to Switzerland and would focus on restoring power in Ukraine.Ukraines Cabinet of Ministers is allocating 2.56 billion hryvnias (almost $60 million) from a reserve fund to purchase generators, Prime Minister Yuliia Svyrydenko said Wednesday.NATO Secretary-General Mark Rutte on Wednesday urged the 32-nation alliances military chiefs to press their national governments to supply desperately needed air defense systems to Ukraine, helping it fend off Russias aerial attacks.Please use your influence to help your political masters to do even more, Rutte said in a video message to top brass as they met at NATOs Brussels headquarters.Look deep into your stockpiles to see what more you can give to Ukraine, particularly air defense interceptors. The time really is now, he said.Russia launched 97 drones and a ballistic missile at Ukraine overnight, the Ukrainian air force said.In the central Dnipropetrovsk region, attacks killed a 77-year-old man and a 72-year-old woman, according to Oleksandr Hanzha, head of the regional military administration. Russias Defense Ministry said that air defenses downed 75 Ukrainian drones over several regions.The international airports of Krasnodar, Sochi, Gelendzhik and Saratov briefly suspended flights overnight because of the drones.In Adygea, more than 200 kilometers (120 miles) from the Ukrainian border, a Ukrainian drone caused a fire at an apartment building that injured 11 people, including two children, according to Gov. Murat Kumpilov.___Lorne Cook in Brussels contributed to this story.___Follow APs coverage of the war in Ukraine at https://apnews.com/hub/russia-ukraine
