* Primary threats include...
A few tornadoes likely with a couple intense tornadoes possible
Widespread large hail and isolated very large hail events to 2
inches in diameter likely
Scattered damaging wind gusts to 70 mph likely

SUMMARY...Bands of severe storms, including embedded supercells,
will continue through the evening as a low-level jet intensifies

environment will support the threat for tornadoes, potentially
strong, and large hail and severe gusts into the overnight.

Could warming of the climate actually be an issue …?

I can't imagine any conclusions could be drawn from the records. In 2003, NWS enacted a policy that led to lower ratings for tornadoes, because they required specialized teams to go survey the area. The rating standards also changed around the 1970s due to Fujita. During the pre-Fujita period, tornadoes were usually over-rated.

Oof. I have a dear friend in Tulsa and I was hoping he wouldn't be in the line of fire.

By that time it'll probably be mostly linear, but the tornado threat will remain, and straight-line winds as well.
 
Was just about to say I'm not sure where the meso is here but this just went TORR.

Makes you wonder if in the near future, we could measure tornado intensity officially in real-time, similar to hurricanes, using all the tools we now have available, instead of relying on damaging a populated area to get the most accurate ratings? I imagine the public could be greatly served by hearing "Level 4 tornado (or whatever) coming into downtown OKC right now!" and could help convey the seriousness of things.
 
Forcing must be beginning to act on atmosphere as well as LLJ increases as cells are blowing up to the south of OKC in Carter and Garvins counties.
You just got to have that sunshine in most cases to break that Cap. Those anvil covering's earlier contributed to keep things suppressed IMHO.

this would explain a lot. That capping at 700 mb is surprisingly resilient and the forcing is too distant to overcome it.

There's also some additional tweets between those two where it is mentioned the cap was gone at 18z but advected back in by 00z. Delayed trough ejection difficult to overcome with the thick cloud cover.
 
This sucker is starting to ramp up more as it approaches OKC metro, because of course it would.
