That's huge

Okemah looks to be next in line, over 120 MPH GTG sheer on that.

Took an unfortunately turn north just as it entered the city, which is where most of it is located.

If it's still on the ground, it'll either pass over Seminole or VERY close to it.

Someone's asleep at the wheel, at least 2 cells east and southeast of Amarillo have tight couplets. Edit: now TW'd. The 2 cells to it's north also look pretty healthy.

It might be overtaken by the line relatively soon

All the way in far eastern OK

Starting to see embedded rotation in the line. It's a bit early but I wouldn't be surprised if QLCS tornadoes rule the day yet again. Edit; that storm is now tornado warned

Confirmed tornado in NE with the tail end Charlie

I thought we had the first two confirmed tornadoes till I remembered that Memphis words all their warnings as "tornado producing storm". Either way, looks like the current line has some decent embedded rotation, though nothing even remotely discrete for now.

12Z HRRR has quite the volatile environment over Mississippi this afternoon, though it has a bit of a tendency to overdo the extent of isolated convection. As is often the case in these setups, keep an eye out for areas a bit south of the highest risk areas, as they often produce discrete supercells even with somewhat less impressive dynamics, while areas within the main risk areas tend to grow upscale a bit quicker. Just for the heck of it, here's a cherry-picked sounding from AR this afternoon, SRH values are rather impressive.

Wild

Man, I've forgotten how pretty tornadoes are in the plains, we've been getting so many of them in the Dixie Alley and I've missed the clear tornado pictures from miles away.

This should be the first tornado warned cell of the day.

It's a bit muddied since it's so close to the radar site, I guess we'll need to wait for ground confirmation.

Tornado emergency with it now.

Large TOG north of Little Rock.

The cell near Fort Smith is starting to show some rotation, though as it is it has a solid hail core. Edit; now tornado warned

Confirmed TOG now, cool CC feature.

Supercell east of Thomasville looks to be going to town.

Nice signature but it's very close to the radar site.

Big time TDS with that cell now

It might be occluding now or cycling, it may have been impeded by some junk convection to its south.
