OMAHA, Neb. – A major winter storm threatened to blanket parts of the middle of the country with more than a foot of snow Monday, promising to disrupt travel and forcing the closure of some coronavirus testing sites.
The National Weather Service said at least 4 inches (10 centimeters) of snow is expected across most of an area stretching from central Kansas northeast to Chicago and southern Michigan. Parts of southeast Nebraska and western Iowa could get more than three times that much by Tuesday morning.
Several coronavirus testing sites in Nebraska and Iowa were closing early Monday because of the snow. More than 10 inches (25 centimeters) of snow had already fallen in parts of eastern Nebraska by Monday evening.
National Weather Service meteorologist Taylor Nicolaisen said 10 to 15 inches (25 to 38 centimeters) of snow was likely between York, Nebraska, and Des Moines, Iowa, and that it has been at least 15 years since that area received more than a foot of snow in a single storm.
“This is historic snow,” said Nicolaisen, who is based near Omaha, Nebraska.
Many schools and businesses closed Monday as the storm moved across the region. In western Iowa, Missouri Valley Superintendent Brent Hoesing reworked the lyrics of the 1970s hit “I Will Survive” to tell students in his district to “So Stay Inside."
Officials urged drivers to stay off the roads during the storm, especially during the heaviest snowfall in the afternoon and evening. Nebraska State Patrol troopers responded to more than 200 weather-related incidents Monday.
“Do not travel unless it’s absolutely necessary,” said Nebraska State Patrol Col. John Bolduc.
Roughly 250 semi trucks pulled off the road to wait out the storm at the Petro truck stop alongside Interstate 80 in York, Nebraska. Manager Rachael Adamson said she could see knee-high drifts and that the maintenance man had to go out every 30 minutes to shovel the sidewalks to keep up with the snow.
“We haven’t had this much snow in quite a few years," Adamson said.
Iowa State Patrol Sgt. Alex Dinkla said road conditions deteriorated quickly and numerous vehicles slid off roads in central Iowa.
“The big thing that people are seeing is that this snow system is packing a big punch,” Dinkla said to the Des Moines Register. “As we have seen this system move into Iowa, the road conditions go from zero snow on the road to an immediate totally covered roadway in just a matter of minutes.”
A section of eastbound Interstate 80 was closed in central Nebraska Monday afternoon following a crash. And Missouri officials urged drivers not to travel on Interstates 29 and 35 in northwest Missouri into Iowa. The agency said most roads in the area were covered with snow and heavy snow continued falling Monday afternoon.
”If northern Missouri or Iowa are part of your travel plan, please re-route or find a warm, safe place to wait out the storm,” the Missouri Transportation Department said.
Elsewhere in the U.S., a storm moving across the Southwest on Monday and Tuesday was forecast to bring gusty winds and snowfall, the weather service said. Over the weekend, more than a foot of snow fell in Southern California’s mountains, making driving conditions hazardous. Interstate 5 was shut down Monday in the Tejon Pass between Los Angeles and the San Joaquin Valley. Wind, snow and ice also forced the closure of State Route 58 through the Tehachapi Pass.
Until recently, California had been experiencing significantly dry weather accompanied by relentless wildfires. A band of clouds suggested more rain could fall Tuesday in areas north and south of San Francisco Bay, bringing the threat of possible flash floods and landslides in areas scarred by the fires.
Forecasters at the Sacramento-area National Weather Service office predict an abundance of snow in the Sierra Nevada between late Tuesday and Friday that will make travel through the mountains difficult.
A major winter storm buried northern Arizona in snow on Monday while sending flurries to the outskirts of Las Vegas and Phoenix.
And most of Nevada was bracing for another series of powerful winter storms that could bring rare snowfall to the Las Vegas Strip late Monday or early Tuesday and several feet to the mountains above Lake Tahoe with winds up to 60 mph (96 kph) by Thursday.
Up to 6 inches (15 centimeters) of snow fell Monday in the Reno-Sparks area, where up to 10 inches (25 cm) is possible and up to 20 inches (50 cm) in the Sierra foothills above elevations of 5,000 feet (1,828 meters) on the edge of town by Thursday.
Three to 6 feet (91 cm to 1.8 meters) of snow is forecast in the Sierra above elevations of 7,000 feet
