Severe Weather Threat May 17-19, 2025

VWP shows a lacking LLJ as expected and LLLR are piss poor, but there’s plenty of cape and streamwise vorticity is good.

You're all good, it really did look like it had missed town on radar. Not exactly sure what happened.
Tornado occluded, which did weaken it, and on radar, which was far away from it, looked like it dissipated.

But below what the radar beam could detect, the tornado definitely was still on the ground, and I wouldn’t be surprised if it strengthened a little before it died as it shrunk due to conservation of angular momentum.
 
Tornado watch got extended east, into DFW:
To quote Yukari from Persona 3:
"This thing won't give up!"
Never thought I'd see a Persona reference on a tornado thread, but there's a first time for everything, I guess (LOL!).

Mesoscale Discussion 0868
NWS Storm Prediction Center Norman OK
0820 PM CDT Sun May 18 2025

Areas affected...Parts of north-central Texas

Concerning...Tornado Watch 288...

Valid 190120Z - 190215Z

The severe weather threat for Tornado Watch 288 continues.

SUMMARY...The supercell tornado threat continues, though it is
unclear how far east the risk will spread.

DISCUSSION...A well-established supercell with a history of
producing tornadoes and very large hail continues across parts of
north-central TX. This storm is still in a very favorable
environment -- characterized by 270-300 m2/s2 0-1km SRH (per nearby
VWP data) and strong surface-based instability. Given this
environment and the ongoing strong mesocyclone, the tornado,
large-hail, and damaging-wind threat continues. It is unclear how
long this supercell will maintain its current intensity with
eastward extent, as it gradually encounters increasing inhibition
(sampled by FWD 00Z sounding). However, the aforementioned strong
mesocyclone and large storm-size may allow it to persist -- with an
accompanying all-hazards risk.
