IIRC there was something on this last year, but I think it was more of a sit down brainstorm thing. Isn't 11/13 a Wednesday? Isn't that a typical EBS 1pm siren test day during 'nado season?
Anyway, it really wouldn't take much to disrupt our aging/overstressed grid. What is really driving this test I am not sure...I am inclined to agree with Weisshaupt though, there are so many "readiness" ops going on...in my thinking this is just more confirmation that the state knows stuff is about to hit the fan...if they are thowing at the fan as well is an issue up for discussion, but preparing they are. I'll assume the worst and hope for the best as always, but even the best of a crappy scenario is still, well crappy.
