PDS warning with this storm

Maybe strong embedded tornadoes? I'm not sure why they went 15 percent hatched, but so far there has been at least one embedded tornado doing some damage and has had a tight couplet for a surprisingly long time considering it's embedded in the line. It's also in a radar dead zone so it's hard to know for sure how long it's been in the ground.

The storm between Alexandria and Nelson has a confirmed large TOG. Has a nice TDS signature as well.

Confirmed TOG near Sinai SD.

SPC upgraded tomorrow to a moderate risk for MN.

Two warnings now and the western one has a decent couplet. Weird that they're not putting out a watch yet.

Some 95 mph bins starting to show up on velocity scans north of O'Neill Nebraska, warning out for that area is for 90 mph. Very impressive wind event underway. ASOS report for O'Neill of a 76 MPH gust, with mesonet from the area topping out at 88 mph.

SPC added an significant tornado contour in northeastern SD despite expecting things to grow upscale very quickly. Even with a messy storm mode, backed surface winds and eye-raising instability can lead to a couple of significant embedded tornadoes. Here's a cherry-picked sounding in SD from the latest HRRR.

A couple of confirmed tornadoes embedded in that line now. It's hard to stay on top of it given how fast they spin up and disappear, which is probably why they're doing this.

That monster cell took a bit of a north turn so the NWS is spreading out 3 seperate warnings in all directions. Probably smart given what some of the Oklahoma tornadoes have done today.

Absolutely vicious rotation in the cell just south of Lockett TX, hope it's not a populated area.

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.
