Powerful storms damage homes in Colorado, Wyoming

A 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. The storms followed a round of nasty late spring weather that pummeled the region Wednesday.
