WINDSOR, Colo. (AP) — A large tornado skipped through several northern Colorado towns on Thursday, destroying dozens of homes, flipping tractor-trailers and freight rail cars, and killing at least one person.

The National Weather Service said the tornado touched down just before noon near Platteville, about 50 miles north of Denver. Over the next hour, it moved northward past several towns along 35-mile-long track toward Wyoming.
