Today was my first time using the Spotter Network--simply awesome. Took a little while for me to get everything set up with GPSgate, but the unbelievably improved cell coverage over the PH coupled with the addition of a cellular antenna (probably biggest contribution was the latter--can't believe I never used one before!), I was able to get data uploaded and downloaded throughout the chase.
Forecast had high bust potential, so I extended my stay in Plainview for an additional night to allow for time to dictate the proper chase spot. Satellite ended up being the key to my evolving chase strategy today. Unlike in previous days, OFBs were not as clear on radar today. An E-W oriented boundary in a Parmer to Swisher Cty, TX line had bubbling Cu most of the day. I concur that the midlevels were almost absent, but the 300mb winds were rapidly accelerating in the area suggesting parcels hitting the LFC may get adequate ventilation. Sfc winds backed rapidly during the late afternoon as a small line finally began to hit radar returns along the aforementioned OFB. Once I saw bold convection had evolved, there was no chasing to do: all I had to do was move 45 miles NW of Plainview. Shockingly easy considering the seriously difficult forecast from this am.
Adding to the excitement was the sharp right turn the storm took and the dominance of the western cell. Rapid radar evolution into a screaming eagle was much, much more than I could have hoped for today.
As I approached from the SE, the base was obviously very high courtesy of the T/Td spreads, but the midflow feeder bands, rock hard updraft, and initial "classic" supercell appearance were like nothing I've chased since '99 or '00. All by itself with unobstructed inflow air and sunshine beaming through along the dry rear flank. Crepuscular rays beamed around the updraft.
Ended up picking a sweet spot to get out and film and finally met, face-to-face, Paul and the COD crew (talk about wild--the Spotter Network showed who I was parked next to making the introduction easier). Good meeting you Paul!
Despite being in clear air, the meso started spitting out nickel size hail forcing constant repositioning southward on 385. The transition to a right-moving (almost pure southward) HP was problematic so late in the day. Nevertheless I can confirm the tornado already mentioned above. It was a cone before roping during occlusion. Multiple new funnels formed on redeveloping updrafts, but the storm slowed and the storm transitioned to a pure HP. While TOR continued to be issued, none of the updrafts matured similar to the one when the tornado occurred (and it occurred largely as the storm suddenly shot south in a short burst likely bumping local helicity).
As darkness ensued I shot incredible front flank lightning and eventually was consumed by the RFD of another occluded meso. I moved southward into Littlefield to allow the storm to pass overhead. Though TORs continued well after dark, visual features were lost as the CC and CG output of the storm pulsed down.
Would never, never have hoped for the luck I got today. Nature was generous. Off to rest and try to rinse and repeat tomorrow.
