Convective modes will determine the outcome for those out chasing today. "Loaded gun" soundings will make for some explosive development. Parallel front / boundary flow may cause cells to morph rather quickly from isolated cells into segments, and I would not be surprised to see a potentially dangerous QLCS tornado chase situation sooner than later. There will likely be isolated, tornadic supercell(s) in the early stages (maybe further south) if you can reposition quickly as the forecast gels. Could be big problems if isolated cells form and mature west of the DFW region, so that is something to watch. Any new chasers should be aware of storm speeds (40-45 kts) and potential traffic issues around populated areas.
