OKLAHOMA CITY — More snow was falling 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 and northwest Arkansas, with some places reporting 8 to 12 inches of snow. The snow and rain was expected to end later Sunday.
Authorities have attributed at least four 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, and forecasters say temperatures should rebound into the 60s as soon as Monday.
The Oklahoma Department of Transportation urged people in the eastern part of the state not to travel on the snow-packed and slick roads if they didn't have to, but said roads in the western part of the state were improving as the weather did.
Authorities reported dozens of wrecks amid heavy snow and high winds, many of them with injuries. Single deaths were reported in Missouri, Kansas and Oklahoma.
