Chase Area:  North Texas
Weak vertical shear and very strong CAPE was present along a slowly southward moving cold front.  When convection fired, the front was on top of DFW, which strong convection developing near Grandbury, downtown Fort Worth, and Irving.  I liked the area south of DFW where winds were backed some as a kink showed up in the front.  The surface was roughly 84/72 for most of the day with winds backed southeast at times.  Storm motions were southward, so I positioned myself south of downtown Fort Worth with a great view of the new updrafts developing over downtown.  Amos Magliocco and Rob Hall converged on that point as well, just around the time the first severe thunderstorm warning was issued.

Supercell Moving South
Just south of downtown Fort Worth, our storm began to show organized weak rotation with occasional needle funnel spin-ups.  Small hail up to nickel sized was observed near McCart and I-20.

Structure Time
West of Edgecliff Village, our storm began to shrink and had decent structure for several minutes, as a new updraft developed back towards the west near Benbrook.

Supercell at Sunset
We drove south and observed a rotating wallcloud south of Lake Benbrook.  This updraft was engulfed in rain and small hail, so we drove southwest towards Grandbury.  Rob and I encountered 1.5 inch hail north of Grandbury, Texas.  We stopped to get food in Grandbury at dark, and heard about the Arlington, Texas, tornado.
