Well it certainly was a beastly cap on the FWD special sounding. Wasn't so obvious at OUN, but it's possible the smoke was still driving north up I35 when the balloon went up.
Anecdotally, I've seen quite a few lines/linear segments approach the DFW metroplex this year with the primary tornado risk being with any cells that popped out ahead, but remarkably little has popped. And this is even with the backdrop of a ton of surface moisture for whatever that's worth. Certainly no lack of overall convection, but the cap has seemed to hold until the main forcing has arrived.
