Light snow continues to fall over much of Nebraska's Panhandle, further hampering travelers already blocked by highway closures.

The slow-moving snowstorm made road travel into Colorado and Wyoming all but impossible Thursday morning.

The Nebraska Roads Department says Interstate 80 was closed west of Big Springs, all the way to Laramie, Wyo. At the north end of the Panhandle, U.S. Highway 20 was closed west of Crawford.

In several spots Wednesday, cars and other vehicles had spun off slick roadways. But a Nebraska State Patrol dispatcher in Scottsbluff said Thursday that no fatalities had been reported.

Authorities say snow is still falling in Chadron, Alliance and Scottsbluff, adding to accumulations of a foot or more in some places.
