I am always reminded of the April 3 2012 event, when mesoscale outflow boundaries from overnight storms passing and collapsing nearby set the stage for rotating supercell development to focus along those residual boundaries.
We'll need to watch the wind shifts at various atmospheric levels closely tomorrow, along with any localized variations in cloud cover affecting CAPE. I'm sure some areas will underperform.due to subsidence, while other areas nearby could overperform if the boundaries can align.
It bears watching, but I'm often of the "wake me up when the sun comes out" school of storm preparation.

It's also possible storms developing tonight over southern Oklahoma near the river move into the DFW region overnight and work over the atmosphere a bit reducing the overall severe weather threat during the day on Wednesday. Some models show this while others aren't quite sold on this scenario. As it is most models keep DFW highs around 70 tomorrow or lower in afternoon depending on the progress of the frontal boundary.
18z HRRR has shifted a bit south overall toward the Waco region (warm sector) in terms of explosive supercell development Wednesday afternoon into early evening, but this could change in future runs. Overall, still a lot to watch and folks should definitely be weather aware across that entire region tomorrow. Threat looks to shift south into the HC and AUS/SA corridor overnight into Thursday morning but hopefully with the loss of daytime heating storms will be more manageable then.
