DFW Dopers - what's up with the storms?

Is my memory just tragically short, or is this the worst storm season we’ve had in a long time? It seems like we’ve been socked by one after another lately. And in my area in particular (Plano/Allen) we got hammered a few weeks ago, which gusting wind knocking down almost every single fence in my neighborhood (and in much of the area).

What’s the deal? Has it been like this before and I’m just not remembering?
