I'm no meteorologist by any means, but I'm pretty sure this dude just witnessed a tornado pass directly over the top of him.
It looks like he's hanging out at a golf course, when he sees some dark swirling clouds headed in his direction. "This does not look good... Not good."
Instead of heeding the advice that has been given since elementary school, this dude does not seek shelter in a basement room with no windows and cover himself with a mattress. No, instead he chills on the clubhouse patio to get some sweet footage.
I guess he made it out okay if he was able to upload the footage when a shard of a tree could have easily impaled him.
