LITTLE ROCK (AP) — Major roads in Arkansas were open Wednesday, but many secondary roads were icy enough to force some school districts to call off classes for a third consecutive day.

The most significant problems were in northern Arkansas between Fayetteville and Batesville and in central Arkansas in the Little Rock and Hot Springs areas, though schools closed in other areas, too. Some schools opened late or had limited bus service.

Little Rock area public schools were closed Wednesday because so many neighborhood streets were icy. Major routes in the metro area were open.

Arkansas Highway and Transportation Department spokesman Randy Ort said road crews were still working around the clock to keep highways from freezing over.

Bright sun on Tuesday melted some of the snow from Monday's storm, but standing water froze overnight, making the roads hazardous.

Ort said drivers still have to use caution.

"Some people are driving as if conditions were normal today, and some people are driving with extra caution today. That's not a good mix, with the variation in speeds," Ort said. "One little patch of ice to one motorist can really foul up a lot of (other drivers') day."

Ort said some of the moisture is drying, which will help reduce the hazard.

The 7.2 inches of snow recorded in Little Rock was the most since December 1988 and was the eighth greatest snow total in the city since records have been kept, according to the National Weather Service.

A 29-year-old pedestrian died early Wednesday after being struck by a vehicle on Interstate 30 in Little Rock. State police could not immediately say whether the death was attributable to the weather.

Gov. Mike Beebe, who called off work for Little Rock-area state employees on Tuesday, gave workers in the city a couple of extra hours to get to their jobs Wednesday.

Another weather system that could bring snow to the southern half of the state is expected to reach Arkansas on Thursday, forecaster John Lewis at the National Weather Service said.

Up to 2 inches of snow is expected, with about an inch falling in Little Rock on Thursday night and Friday morning. Once again, Little Rock is in the transition zone of the storm, where there could be rain, sleet, snow or a combination.
