Powerful storms damage homes in Colo., Wyo.

A Thursday, June 7, 2012 photo provided by Andrew Kniss shows a funnel cloud, seen from Kniss's car on Highway 34, near Wheatland, Wyoming. The rare quarter-mile-wide tornado cut a swath across mainly open country in southeastern Wyoming, damaging homes, derailing empty train cars and leaving one person with minor injuries, officials said. The twister was part of a powerful storm system that rolled through parts of Colorado and Wyoming Thursday afternoon and evening, packing heavy rains, high winds and hail.
