A weekend of ferocious winter weather could see low-temperature records set in the US heartland

O’FALLON, Mo. — Icy winter weather blanketed the U.S. on Saturday as a wave of Arctic storms threatened to break low-temperature records in the heartland, spread cold and snow from coast to coast and cast a chill over everything from football playoffs to presidential campaigns.

As the three-day Martin Luther King Jr. Day holiday weekend began, the weather forecast was a crazy quilt of color-coded advisories, from an ice storm warning in Oregon to a blizzard warning in the northern Plains to high wind warnings in New Mexico.

“It’s, overall, been a terrible, terrible winter. And it came out of nowhere — two days,” Dan Abinana said as he surveyed a snowy Des Moines, Iowa. He moved to the state from Tanzania as a child years ago, but said “you never get used to the snow.”

The harsh weather in Oregon played a role in three deaths.

In Portland, medical examiners were investigating a hypothermia death as freezing rain and heavy snow fell in a city more accustomed to mild winter rains, and hundreds of people took shelter overnight at warming centers.

Portland Fire and Rescue also reported the death of a woman in her early 30s on Saturday afternoon. An RV caught fire when a small group of people used an open flame stove to keep warm inside and a tree fell on the vehicle, causing the fire to spread. Three other people escaped, including one with minor injuries, but the woman was trapped inside, the fire department said.

Authorities in Lake Oswego, Oregon, said a large tree fell on a home during high winds Saturday, killing an older man on the second floor.

Weather-related deaths already were reported earlier in the week in California, Idaho, Illinois and Wisconsin.

Nebraska Gov. Jim Pillen announced a state of emergency, citing “very dangerous conditions.” Up to 2 feet (0.6 meters) of snow fell in some areas over the past week, and wind chills were well below zero.

“This event is not going away tonight. It’s not going away tomorrow,” Pillen said at a news conference “It’s going to take a number of days.”

About 1,700 miles (2,735 kilometers) of Nebraska highways were closed. State police assisted more than 400 stranded motorists, said Col. John A. Bolduc, head of the Nebraska State Patrol.

In Iowa, cars were stuck for five hours in blowing snow on Interstate 80 after semitrailers jackknifed in slippery conditions. State troopers had handled 86 crashes and 535 motorist-assist calls since Friday, State Patrol Sgt. Alex Dinkla said.

Road crews were “working the snow-blowers like crazy,” Dinkla said, but high winds were blowing snow right back onto roadways.

Governors from New York to Louisiana warned residents to be prepared for worrisome weather.

Parts of Montana fell below minus 30 degrees Fahrenheit (minus 34 degrees Celsius) Saturday morning, and the National Weather Service said similar temperatures were expected as far as northern Kansas, with minus 50 F (minus 46 C) possible in the Dakotas. In St. Louis, the National Weather Service warned of rare and “life-threatening” cold.

“We’ve had, now, multiple back-to-back storms” parading across the country, weather service meteorologist Zach Taylor said. That typically happens at least a couple of times in the U.S. winter.

Still, to Eboni Jones of Des Moines, it felt unusual for “how much we’re getting all within one week.”

“It’s pretty crazy out,” Jones said while shoveling snow.

Grant Rampton, 25, also of Des Moines, braved a wind chill of minus 20 F (minus 29 C) to go sledding with friends at a golf course, fighting off the cold by wearing layers of clothing and insulated socks and keeping in constant movement.

“It’s a great state to be in,” said Rampton, a lifelong Iowan.

“There’s not as much to do, in winter especially, but you can make your own fun, like out here, sledding with your friends.”

The temperature in parts of Iowa could dip as low as minus 14 F (minus 26 C) on Monday, when the state’s caucuses kick off the presidential primary season. And forecasters said it would be Wednesday before below-zero windchills go away.

Republicans Ron DeSantis, Nikki Haley and former President Donald Trump all canceled campaign events because of the storm.
