Blizzard conditions are present over Iowa this Wednesday morning with strong winds and blowing snow. The featured map presents Iowa DOT / State Patrol reported winter road conditions valid at about 5 AM. A remarkable contrast is shown with conditions rapidly changing from normal to travel not advised.
