Yea. I think sometimes intense sunshine is unhelpful because it produces a deep dry adiabatic layer. Supercell tornadoes tend to like areas where there the low-level lapse rate isn't too steep. Downdrafts don't become too dominant then. You also get more backing near the ground when the first 1000 feet is a little more stable because there aren't as many dry thermals mixing westerly momentum down from above. The most likely place for big tornadoes usually isn't in the middle of a bubble of high SBCAPE. It's usually around the edge of the SBCAPE bubble (i.e. where there's a sharp SBCAPE gradient). I think tornadic supercells are often pulling in the most unstable air from a slightly elevated layer, but the meso is able to "dig" down and pull in surfaced based air as well. For example, you might have a MUCAPE of 1400 j/kg for a layer rooted around 900 hPa on the "cool" side of an old outflow boundary, but the storm is also pulling in surface parcels with CAPE around 700 j/kg. The surface parcels probably have a fairly high LFC, but the vacuum effect of the meso can get them up there. These parcels have a lot more "backed" momentum profile than those entering the storm from the 900 hPa level, so they can contribute a lot of extra spin to the meso, helping to reinforce the upward vacuum effect. On the warm side of the outflow boundary you might have SBCAPE of 2500 j/kg, but meso's are all weak and elevated due to strong cold pools and lack of near-surface backed flow.
