Severe WX April 11th-13th, 2020 Severe Weather Threat

[Shakespeare2016]

Is that the final rating? Or is NWS LIX still assessing the path?

I don't think it is the final rating and believe that it is still preliminary.

 

[Equus]

The second long track tornado (EF3) behind Bassfield has a path length of over 80 miles long and 1 mile wide... which is extremely substantial, though totally buried in the shadow of the Bassfield tornado

I believe the rating on that tornado is also still preliminary.

 

[Equus]

I haven't heard any survey details at all on it so wouldn't be shocking if they've barely started on that one

Just saw this on Twitter. This house with anchor bolts was completely swept away!

Nixville, SC tornado (Hampton Co) high end EF3, 165 mph per DAT (prelim still).

I think these are from the two separate monster tornadoes. One was at least two miles wide and the other one was 3/4 mile wide. I see a potential EF5 rating for both of them.

Nixville, SC tornado (Hampton Co) high end EF3, 165 mph per DAT (prelim still).

I saw that the long track SC one has the chance to go EF4 (not sure if this one below is the same one).

edit, it looks like the same one.

 

[Shakespeare2016]

Yeah I saw that the long track SC one has the chance to go EF4.

So we could potentially be looking at least 3 or 4 violent tornadoes from this outbreak.

 

[Equus]

LIX apparently has an announcement coming up from their section of the track, not out of the question the first tornado in that cell could be bumped to EF4.

 

[Equus]

Impressive number of high end tornadoes from this event... 4/12 definitely goes down in the record books

 

[Evan]

Just further proof that insane SRH and wind shear can really make up for a lack of instability in a major way.

I don't want to imagine what would've happened had we had about 500-1000 more CAPE and marginally better lapse rates.

 

[andyhb]

Gonna guess that we wind up with two EF4+ out of that lead supercell in S MS. That Bassfield path is mind-boggling (both in size and intensity at times).

I can't see why they will not go EF5 on that tornado but whatever. Even if they don't get an EF5 rating it was still an incredible event.

All comes down to construction quality at the end of the day, now matter how insane the contextual damage is. I’d say it was almost certainly an EF5, but whether it hit anything well-built enough to prove this 100% remains to be seen.

Yeah I understand what you mean. However, I do believe that is the largest tornado ever recorded in Mississippi.

 

[Equus]

It's one of those cases where we'd have probably had back to back F5s if this were the 1990s, but now construction quality is scrutinized so closely I'm sure any EF4 damage points are going to be few and far between. Makes it hard to compare events.

 

[wasatch]

I kinda feel like 165 mph is their way of saying "would have been F4 on old scale" - same with 190+ for F5...

 

[Equus]

Walthall has been upgraded to 170/EF4
