Wild Weather Leaves Trail of Ruin across Heartland

People in America's heartland are cleaning up Wednesday after dozens of tornadoes wreaked havoc across the region, 20 of them in Texas.

Little remains of a church in the Texas town of Mineral Wells, just west of Dallas, where two powerful tornadoes touched down.

"I saw the funnel cloud start to drop. I saw a small tail come down. As soon as it touched, debris flew up into the air, a bunch of big black shingles. I saw the transformer blow and it looked like it picked up and it headed a little bit east," resident Will Beyer said.

Another resident said, "Next thing I know I see the stuff start peeling off the roof and the boards are just flying through the air. That's when I knew we had to get inside."

The twisters caused extensive damage but no injuries.

"We're very thankful that this didn't occur earlier in the evening because it would have been rush hour and there could've been four or 500 cars here just getting off of work," Mineral Wells Police Chief Dean Sullivan said.

Aside from the tornadoes, flooding is causing problems in other parts of the nation's midsection.

In 24 hours, San Angelo, Texas, got the most rain it's seen in 35 years, trapping more than 20 drivers in sinking cars.

There was also massive flooding in Shreveport, Louisiana, paralyzing many parts of the city.

"I have never seen this much rain. I've been in Shreveport for 32 years," resident Shanika Whitaker said.

Much of Denver is also flooded, with rushing water – even whitecaps – where there should be a park.

And in the Rockies, a snow storm hit just a month away from summer.

Forecasters are telling residents to brace for more threatening weather throughout the remainder of the week.
