Authorities on both sides of the state line say roads are snow-packed and icy, causing accidents and hazardous driving conditions throughout the metropolitan area and outstate regions.
Snow crews are struggling on the day after Christmas to make headway against unrelenting snowfall and winds that are causing drifts. Tow trucks are running nonstop.
Roads that were cleared at one time are drifted over an hour later, said Kansas City public works spokesman Dennis Gagnon. Many side streets have yet to see a plow.
"We're not progressing as quickly as we would like," Gagnon said. "We're having to drive slower, and this is putting us behind.
"Patience is the word of the day. We're trying to get this clear for Monday morning."
Dispatchers for both the Missouri and Kansas highway patrols report many injury accidents and countless slide-offs.
Many highways, including Interstate 70, were closed part of the day in western Kansas.
The National Weather Service is calling for an additional 2 inches of snow today with more tonight and into Sunday. The forecast also calls for widespread blowing and drifting.
The snow should be around for a while as temperatures are expected to remain below freezing for several days.
