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

He also posted some damage footage from Bassfield, which is quite bad, although I would guess from the contextual damage that the homes that were swept away weren't anchored properly.

 
Strong rotation just west of Ellicott City, MD. That's headed up toward the Baltimore metro area.
 
If that produces, it's going to be a problem because that's a pretty densely-populated part of the south/west Baltimore suburbs.
 
Keeps cycling in and out between scans...

Trees and power lines down in Montgomery Co., MD (northern suburbs of DC). Probably straight-line wind damage.
 
EF3 confirmed in E Chattanooga.

4/27/14 was the Vilonia, AR EF4 that was subject to so much controversy over the rating.

There was & still is some controversy over the 27 Apr 11 Tuscaloosa-Bham tornado rated EF-4. Many storm survey experts said they saw EF-5 destruction. But the storm still stands as a strong EF-4.

So far, just from the naked eye, it's hard to identify any EF-5 damage indicators along the damage path, despite numerous wind estimates exceeding 200 mph on radar. However, on TWC just now, Mike Seidel just reported from the foundation of what was once a house. Looked like it was just about swept clean.

Just based on the pictures I've seen, I'd be shocked if the houses it swept away were constructed well enough to merit an EF5 rating. The vegetation and vehicle damage near those clean foundations isn't indicative of EF5 intensity, so those homes were probably of relatively weak construction and/or not anchored to their foundations properly.

Given recent trends, I'll be impressed if anything in the outbreak gets rated higher than 165mph EF3. In many WFOs it would probably take a skyscraper being reduced to dust scattered thousands of miles for EF4 to even be considered

I could see the two big Mississippi tornadoes getting EF4. I just don't think there are many EF5 damage indicators for a tornado to hit in rural southern Mississippi.

Wait, did you say a skyscraper being reduced to dust and scattered for thousands of miles? Sorry, at best that's a 130mph EF-2 in LZK's territory. Maybe 120mph. Depends on the PSI of the concrete poured for the building.
