I was able to find some stuff at the NCAR archive. Let's look at where the precip was occurring at the time of the sounding:

and the surface map at that time:

You probably noticed the sounding at OAX still had a healthy cap of 50 J/Kg, and what we see is that storms were developing north of a boundary at the surface, where temps were only in the 70's, so convection was not occuring in the region with both large CAPE and large shear.
I think you get a better appreciation for the strength of the cap in this sounding plot:

Thanks for the suggestion though - and please keep thinking of more.
