Snow and ice accumulations ranged from a trace to a half-inch in far western Kentucky.
``All of our roads are extremely slick and hazardous,'' said Jerry Beasley, a Kentucky State Police dispatcher at Mayfield.
Forecasters warned that a second round of precipitation in the region later Thursday could bring ice accumulations of a quarter inch, along with possibly 1 to 3 inches of snow.
State police at Mayfield received reports of two dozen accidents within two hours because of slick roads, Beasley said. ``Most of them just slid off the road,'' he said.
The accidents resulted in two minor injuries, he said.
A low-pressure system combined with an abundance of moisture in the air, creating the wintry mix.
