I think I saw vortex95 mention this but the reflectivity gradient along the leading edge of those storms was about as textbook as you'll see for these parts, hell that would even be impressive anywhere else. Anytime you see a super strong wind signature like that I guess there is the risk for a brief spinup but I don't think there was anything really pointing towards a tornado or rotation. Velocity signatures on all radar sites was pretty evident with straight-line wind signatures and if you look at the environment, there really wasn't anything supportive for tornado formation. Just a textbook classic setup for straightline winds and widespread given the development of a cold pool.
