Drivers in Iowa and Nebraska were warned to be careful or stop driving altogether starting Wednesday evening as the first major winter storm of the season heads into the central Plains from the Rockies. Strong winds are expected to create blizzard conditions.
Light snow is also expected at Chicago's O'Hare International Airport on Thursday and strong winds could make visibility poor. That combined with low clouds, could cause delays at the nation's second-busiest airport, National Weather Service forecaster Jamie Enderlen said.
Iowa officials advised drivers to avoid most roads from Wednesday night through noon Thursday, but native Laurie Harry, a manager at a Casey's General Store, expects to drive to work Thursday morning.
