0525 Chase - HP Everywhere, Then a Surprise

Well... it was a tough chase. Best dynamics in northern panhandles, CAPE and frontal convergence much farther south. We were near Lubbock when the whole area exploded into rapidly evolving into HP supercells. No tornados were seen, and we managed to dodge all of the hail successfully. Nothing photogenic, so no photos of all of that. On the drive back to Amarillo, everything exploded again, along a ENE-WSW line right through Amarillo. From near Plainview we saw what looked like dixie-cup shaped extrusion suddenly appear from the top of the anvil of a storm to the north. Very odd. We really don't quite know what to make of it... So... that's the one picture for today:
