CHEYENNE, Wyo. (AP) — A rare, quarter-mile-wide tornado cut a swath across mainly open country in southeastern Wyoming, ripping off roofs and shingles, destroying outbuildings and derailing empty train cars.

The twister, which carried winds of up to 135 mph, was part of a powerful storm system that rolled through parts of Colorado and Wyoming on Thursday, packing heavy rains, high winds and hail. The storms followed a round of nasty late spring weather that pummeled the region.
