Several tornadoes have been reported in Iowa and Illinois as storms downed power lines and trees. Friday's severe weather comes days after a tornado devastated one small Iowa town, killing four people and injuring 35 others. The latest storm system began overnight in Nebraska before traveling across central Iowa and into Illinois. A weak tornado touched down in suburban Des Moines, according to the National Weather Service. It was also assessing damage from several other reported twisters south of Iowa City and near Moline, Illinois. No injuries or deaths were reported. In Oklahoma, a tornado was on the ground for about an hour Thursday evening.
