OKLAHOMA CITY — More snow fell Sunday as part of a powerful storm blowing through Oklahoma and the southern Plains on the first weekend of spring.

The National Weather Service said there was moderate to heavy snow across northeast Oklahoma, northwest Arkansas and southwest Missouri, with some places reporting 8 to 12 inches.

Jason Nation, who drives a Werner Enterprises tractor-trailer, took a break Sunday afternoon at a Pilot truck stop along Interstate 44 in Mount Vernon, Mo., in the state’s southwest corner. He said he was on a trip from Laredo, Texas, to northern Missouri.

“When we entered Arkansas (early Sunday) it was really a blizzard,” Nation said. “The wind keeps pushing you to the right.”

Authorities have attributed at least five deaths in four states to the weather. Police in Arlington, Texas, said ice on an interstate caused an accident Sunday involving five vehicles and two 18-wheelers. One of the 18-wheelers fell on another vehicle, killing one person.

The storm came a day after temperatures had reached into the 70s.
