To clarify, the reason I say somewhat marginal instability for severe weather is because much of that instability on the sounding you presented is elevated. Even the CAMs indicate a stable layer forming near the surface by the time the storms arrive into DFW (temps only in the low 80s and dewpoints in the low/mid 70s), which will significantly temper downburst potential.
Instability and moisture levels are definitely good enough for prolific rain producers and frequent lightning though, which is already pretty well covered in the current outlooks/forecasts.
