Here's a sat pic and a graphic also.  I noted with interest the wind isobars around this storm - pretty intense rate of knots!

The CAPE as well shown on the RHS certainly vaired with a 2000+ jump in one zone.  Incredible stuff.  The link below has a nice report on the event also:

Also a fantastic site with photographs from many well known chasers who must have all converged in that area at once.  The accompanying photo credited to Keith B Brown and check out the layering with the supercell and the tornado to boot!  Detailed reports from:
