Severe Weather Threat May 17-19, 2025

Ridiculous vegetation damage.
Edit: This was not from the Greensburg tornadoes from last night, it was a different tornado. Not sure which one.

Only thing I see near McKinney is a small shower.

Mistaken, apologies

 

[Ebaad Jaffery]

Cell near Olney, in the general area of Wichita Falls is severe-warned, and is showing rotation.

Isn’t significant tornado EF2-EF5

Yeah, you can look at it that way.

This chart will help. Ignore the box over "significant", I have a script on Wikipedia that highlights potentially promotional words.

That is a good chart.

Quite a bit of veer back veer in that sounding and the cap explains why storms are struggling, although I can verify it is absolutely juiced outside with very gusty winds. This first round struggling some and not becoming fully established is probably worse news for later this evening, theres still a lot of sun in the warm sector across Oklahoma

 

[OH-IOan]

That is a good chart.

The top row is "official" rating classifications from the NWS, and the second and third are overarching classifications. Not sure where the last one comes from, but it works nonetheless.

Looking at Skew Ts, inversion layer is honestly a bit more stout to modeled. This, along with sufficient mixing in the PBL, could help in keeping crapvection in check and actually allow for storms to stay a little more spaced.

This was the second tornado produced by this supercell if I remember correctly, no debarking visible in this area.

Curious to see how intense the contextuals are with the last and strongest tornado are, according to radar.

This also means that it may be more difficult for storms to rise up on the dryline, in North TX right? Or am I lost

That's just an old corn field. I dont really see any damage in those pictures.

At the least, that means that today's ceiling has gotten at least a little bit higher.

Yeah a bunch of corn stalks from last years crops getting blown over isnt that wild

Suns out on the backside of those storms in south tulsa.

No, this is only relevant for OWS convection. The dryline is going to convect once the forcing mechanism arrives regardless if the inversion layer is there or not.

The forcing mechanism for the OWS convection is a mid level cold front, if the inversion layer holds, it will be beneficial for individual supercells in keeping them discrete. Emphasis on the “if”.
