Like most everyone else in Norman, we (Brandon Lawson, Bryan Putnam and myself) flew out the door sometime around 7:30pm as a massive Cb exploded in McClain/Garvin Co. Having to play catchup was fairly frustrating, since we'd driven down to Pauls Valley about an hour and a half earlier hoping something could fire in the primed environment around PVJ-ADM-DUA, but quickly turned around upon seeing the Cu field completely vanish down that way.
The updraft was certainly one of the more impressive I've seen, with a rock-hard anvil laden with pronounced mammatus... about half an hour after there'd been nothing but some benign-looking TCu visible in the western sky from Norman.
We dropped south on I-35, then west to Maysville where the rounded base of the southern/original supercell was visible just to our WSW, so we continued west out of town. By this time, it had just become severe-warned, with the NWS indicating quarter-size hail. It sure looked like it was capable of more than that, though, and sure enough, only a mile or two W of town the thud of ping pong balls on the roof/windshield (with perhaps a golfball or two) began. We retreated east, then dropped south, but not without encountering a bit more large hail... it was clear Maysville was about to get pounded, which it certainly did judging by other accounts/video/pics. After finding a suitable pulloff ~3 S of Maysville, we leisurely observed the great LP structure and anvil-crawlers for half an hour or so.
Later on, after moving southeast of town, structure appeared even better, but of course by this time it had to be completely dark
. This was the best I could do given the (lack of) lighting.
Conveniently enough, the cap appeared to eat the storm alive shortly after it crossed the interstate into poor terrain, so we got home less than 3 hours after leaving, having observed a very nice sup close to home. Pretty sweet deal, other than not having happened maybe an hour earlier.
