Emergency officials set out Saturday morning to see how much damage a violent burst of thunderstorms and tornadoes caused as it swept across the Midwest overnight, killing at least five and injuring dozens. The storm toppled cars and left commuters trapped on an interstate highway as it bore down during Friday's evening rush hour near Oklahoma City. The National Weather Service reported "several" tornadoes rolled in from the prairie, terrifying towns along their paths. (AP Photo/The Oklahoman, Jim Beckel)
