Well, TCU rapidly buliding along the dryline from Beaver County OK to near Pampa to just east of Plainview. In fact, the latest vis satellite shows one storm going up (presumably breaking the cap) in the far eastern OK panhandle just west of Laverne, with another storm going up immediately northeast of Plainview. MCD stated WW to be issued soon, and the strong TCU support this. Currently mesoanalysis on SPC site indicates the best instability of the season so far over northwestern OK with 4000-4500 sbCAPE, south-southwestward into western north Texas with >3000 j/kg sbCAPE. Shear is pretty weak, though southeasterly surface winds in western north Texas are creating a favorably-veered low-level wind profile. Despite this, weak deep-layer shear will probably preclude much of a sustainable mesocyclone risk.
EDIT: LOL Just as I sent that, new blue box came across from eastern TX panhandle and western OK. Hail to 4"... yowsa's... I certainly would like to see a nice supercell now, especially given that the only stuff I've seen this year have been in 1000 CAPE crap... What I wouldn't give to see rock-hard convection. Well, I'd head out from OUN if we had another 10-15 of deep-layer shear (20-25kts is too measely for me w/o a good boundary for a storm to anchor on)...
