Once we'd been picked up, the five of us travelled west towards Abilene where some decent thunderstorms were starting to form over W-C Texas. Near Abilene we took the 83/84 south towards Coleman, chasing a storm to our west that was developing a nice inflow notch, and was subsequently tornado warned. There was evidence of a wall cloud trying to form, with a lot of rotating low-level scud, but alas the storm failed to produce any visible funnel.
A second storm was forming quite well to the southwest, but eventually the net effect was that this second storm had a much better inflow and killed off the previously tornado-warned storm. We headed quickly south to catch up with the second supercell, which had already produced hail up to 2.75in (9cm) over areas near Ballanger (TX).

We quickly filled with gas and headed south, passing through the western fringe of this new supercell just north of Mason (TX). Once we were ahead of the storm, we stopped on several occasions to observe the progress of the storm advancing towards us. This supercell began to develop a nice inflow notch, and was already producing baseball-sized hail in places. The cell eventually became tornado warned, which made us feel slightly nervous given our position, so we tried several times to find a safe canopy or awning to shelter the car underneath to avoid any significant hail damage.
