"Elevated" profiles with deep inversions suggesting little or no potential for supercell tornadoes

Example.   This environment has a deep inversion with large CIN throughout the bottom 3 km, an LFC above 3000 m, and no 0-3 km CAPE.  A supercell that developed in this environment (see radar below) was on the cool side of a stationary east-west surface boundary (not shown), and was elevated in nature, producing no tornadoes.  Even with strong shear-CAPE combinations and vertical shear, and a very low LCL, significant supercell tornadoes would be unlikely with such a deep layer of CIN and low-level stability present, particularly on the cool side of a surface boundary.
