A surveillance camera in a Farmer's Co-Op Store in Pilger, Nebraska caught the terrifying moment that one of the twin EF-4 tornadoes swept through the town last month, demolishing a large part of the building in mere seconds.

One of the go-to "fun facts" of the weather so far this year is that tornado activity is well below average, with this year's preliminary tornado reports clocking in nearly 400 below normal. This week, though, proves more than ever that it only takes one tornado to make it a bad year.
