"We're going to make sure we put a plan in place so that the buses are rolling while it's still safe and the students are back home before weather becomes an issue," he told CNN affiliate WRAL.

The affiliate reported that North Carolina Gov. Pat McCrory canceled his Friday evening schedule on account of the icy conditions.

"We do want to encourage people to be very, very careful on what are anticipated to be very slick roads throughout North Carolina," WRAL reported he said. "We don't want to see anyone take any risks."

Caught in the snow

The snow in Pennsylvania played a role in the apprehension of suspected armed robbers, authorities said.

Investigators in Moon Township, just outside of Pittsburgh, tracked the footprints of three people and arrested them in connection with the robbery of a taxi driver at gunpoint Wednesday, police told CNN affiliate KDKA.

The footprints in the fresh snow, according to police, led from the scene of the robbery to the front door of one of the suspects.
