You need sfc-based instability for any type of tornado threat. You don't necessarily need sfc-based instability for wind damage potential but you need llvl instability otherwise lack of instability can be more indicative of an inversion which limits downward transport.
If we can get MUCAPE values > 1000-1500 J/KG and get decent CAPE in the hail growth zone the light show would be pretty great and there would be a risk for hail.
