Looking for origin of tornado photo

This photo came across my facebook feed recently. Can anyone tell me where this was taken? It’s the second one by the question dated June 5, 2013.

Appears to be a composite according to this.

Thank you.

I can’t figure out what the unnamed city is, though. I’m guessing some place in Europe, given the photographer’s other images on the stock photo website linked to in the article.

I think it’s Graz, Austria.

Yup. Confirmed on his facebook page.
