The National Weather Service issued an ice storm warning for the Interstate 40 corridor and other areas in Arkansas, as a winter storm that's expected to cripple much of the state into the weekend brought sleet that left roadways slick with ice and slush.
Forecasters say significant ice accumulations are expected across central Arkansas late Thursday through Friday.
The winter storm dumped as much as 2 feet of snow in parts of Minnesota, forcing school closures and temporary power outages and delighting skiers who were hitting the slopes despite temperatures in the single digits Thursday.
The Spirit Mountain ski area in Duluth, Minn. welcomed the heavy snowfall, which helped turn the slopes into a party. Attendees included students from the University of Minnesota Duluth and other colleges who were given Wednesday off.
While college classes resumed Thursday, Duluth-area elementary and high schools remained closed. Temperatures were in the single digits above zero Thursday morning and were forecast to slowly fall all day on their way to subzero overnight lows for at least the next few days.
Temperatures plunged to minus 11 in Helena, where a frozen pipe burst and flooded part of the Montana State Capitol building Thursday morning.

The cold snap Thursday set or matched record low temperatures in parts of Montana, including minus 26 in Great Falls. Denton also set a record at minus 23 Thursday morning and Havre's minus 27 reading matched a record that has stood since 1936.
The cold snap is expected to last through the weekend.

Abilene and San Angelo were expected to start getting freezing precipitation by mid- to late afternoon, said Joel Dunn, a meteorologist with the National Weather Service's bureau. San Angelo is forecast to get a tenth of an inch, while Abilene could get a quarter of an inch.
