There were similar trends at this range for the 3/2/2012 and 4/27/11. But you are right, this doesn't happen often and its rare.

Yes it did, it was probably the most accurate in terms of how it depicted the warm sector and the airmass recovery between the waves of discrete. Also, while other models were trying to congeal the stuff quicker to the south like in Arkansas, the RRFA kept everything discrete or semi-discrete. The helicity swaths it outputted yesterday morning was almost a carbon copy of what was experienced. The HRRR has also done great with these last 2 outbreaks too.

Important to note that the NAM suite was horrible with yesterday's outbreak and was also horrible leading up to the Rolling Fork incident. NAM suite has been getting out-performed this year.

Radar velocity scans were showing 3 couplets with TDS. That was a potential trio, one of them would of been rain wrapped.

We are all focused on the current, on going major outbreak. There will likely be no post made until after this current outbreak is over.

Confirmed by Brandon Copic, dual tornadoes on the ground near Keota

The 00z HREF spits out a “super outbreak”. Curious to see the next updated HREF run.

09z RRFS-A and 10z HRRR helicity swaths

10z HRRR

09z RRFS-A is insane, don’t really have the words to describe that scenario. About as high end as you can get. Even tries to get some supercells going out east from northern VA up into PA.

That is pretty extreme. Between the HRRR and the rest of the CAM, this is as an extreme/high-end as you can get outside of a super outbreak scenario. The parameter space and warm sector is indeed impressive.

Dynamics can compensate for lack of instability (high shear/low cape outbreaks). In fact some of the higher end, more substantial outbreaks have featured such setups. Though I live in the Midatlantic (Virginia), I can testify that overcast and 60f temp means very little in the way of hindering the setup. I chased the 2/24/16 outbreak here in VA. There was an overcast all day and temps were bouncing between 50-70 all day. 2 devastating high-end EF3’s struck Appomattox and Essex. Also, our state record tornado that struck Petersburg on 8/6/93 was a high-end F4. That day also featured an overcast and thick cloud deck.

Florist shop in Rolling Fork, made of brick, completely slabbed. Most of the slab was wiped clean. One of the anchor bolts was completely removed from the slabbed and bent. Also notice the tree damage in the background.

Let’s hope it was a drone

A vehicle got sucked into the tornado and lifted into the upper most portion of the vortice. Adam Lucio has video of the vehicle getting sucked into the vortice, won’t share it due to sensitivity but here’s a screenshot of the vehicle going up into the upper most portion of the vortice.

The fact it was close to the radar yet still getting 260mph+ velocities is ridiculous.

Both the debris ball and couplet exceed 2.5mi in width. This is a potential record tornado in progress for width and a potential top-5 violent tornado in terms for velocity. Really hope this isn’t mixing to the surface but given debris is exceeding 40,000ft it’s likely this is an EF5.

Wow….260mph+ gate to gate. It’s been a very long time (since Moore and El Reno 2013 EF5’s) that Ive seen radar velocities this extreme.

Starting to see velocities increase with a tighter gate to gate. Debris ball back on radar now. Don’t think the main/parent violent tornado ever weakened, it obviously moved into a rural area and now beginning to move into a more populated area. This tornado now has a historic feel to it, for all the wrong reasons.

As of what has already happened wasn’t enough, new tornado now going up 30mi back to the SW behind the long tracked violent tornado. Following the same path as the main tornado we been tracking. Debris signature and gate to gate signatures evident.

Very impressive that this tornado been on the ground as long as it has. Definitely a textbook situation to teach concerning what happens when a supercell matures and can get surface based/rooted.

Yeah the duration of this TORE is approaching rare territory.

Very indicative of a EF4+. Not a good thing to see on radar.
