Freak Floods? Or the New Normal?

UPDATE 6/14: And now floods hit Oklahoma City. An OKC official tells CNN, "Areas are flooding that have never flooded before."

Just weeks after flooding in Tennessee, Kentucky & Mississippi killed at least 31 people, floods in Arkansas killed at least 16 people this week. 

Should we keep calling this "freak floods" or "extreme weather"? Or, given that these kinds of severe storms are exactly what climate scientists have been predicting, do we have to re-adjust what we consider "normal"?

As Brad Johnson tweeted, welcome to the Anthropocene.
