Entire low pressure system is taken on that classic comma look with the comma head centered in the St. Paul, Minnesota area.

A middle of the night QLCS spinup whack-a-mole at that. Better grab some caffeine heh

Bowing segment headed this way, number of severe warnings have ticked up in the last little while. Hearing distant thunder now. Tornado watch extended til 5am and a few more counties to the east are included in it.

Oh joy, warned for 70mph winds and baseball sized hail. This won't be fun.

Lots of lightning and some strong wind gusts but looks like the hail diminished and the remnants of that core passed north of here. Time to finally sleep.

Update: A friend in Jonesboro tells me 22 injured, only two that required hospitalization and none life-threatening. The coronavirus shutdown ironically probably saved a lot of lives.

Tim Marshall is out and about in Jonesboro. Going to be an interesting survey.

Preliminary rated low end EF3, 140mph. Let the disagreement begin

To be fair most structural damage didn't seem TOO high end, and I'd agree mostly on structural damage alone, but I have never in my life seen anything below a mid EF4 cause vehicle damage anywhere close to what this one did.

Maybe it wasn’t as strong as it looked. Tuscaloosa is a little bigger than Jonesboro. The tornado *looked* similar in size and strength as the Tuscaloosa tornado. Only about a dozen injuries where as Tuscaloosa had several hundred injured and 52 fatalities.

Yeah the lack of fatalities certainly gives credence to a lower intensity, structural damage alone would line up with it as well as only a couple houses were damaged to a more than EF2 level from what I've seen. Not at all surprised really but I wish vehicles were a more widely standardized DI since I've seen photos of multiple cars mangled far beyond structural damage would seem to indicate. Seemed like an extremely narrow core of highest intensity so maybe the strongest core didn't hit anything major?

On another note check out the massive swath of wind damage in Tennessee from last night, those bowing QLCS segments probably did more damage than the early day MDT and ENH combined

1630z verification not including the Tennessee swaths (occuring after verification cutoff times)

The severely mangled vehicle that was shown was a mail truck, not a typical vehicle. Obviously constructed differently, and lots of non-structural metal paneling to rip apart. Lots of surface area too.

I don’t agree with Tim Marshall’s reputation of being overly conservative. He’s very objective and middle of the road if you actually take the time to read his surveys. Also I never saw any clear cut EF4 damage in any of the photos or videos posted. I feel like a lot of the EF4 speculation is a result of how the tornado itself looked. Just because it looked like Tuscaloosa, doesn’t mean it was capable of that caliber of damage.

My only real argument was vehicle damage and claims of unusually high TDS height, so if no more 'standard' vehicles were thrashed in that manner then the structural damage lines up pretty well with the rating. I'm kinda surprised there wasn't worse structural damage but this seemed even narrower than Cookeville, so while I'm sure there was probably low EF4 potential somewhere along its path I doubt it hit anything with that core at its peak. I'm way more impressed with how fast it went from wall cloud to Tuscaloosa 2.0 than the damage dealt anyway lol

Also unlike Cookeville, everyone survived in the homes that were hit, and usually in EF4 your chance of survival in even a well built frame home heads rapidly towards nil... I suspect Covid-19 actually SAVED some lives as the commercial district seemed harder hit and most non essential retail businesses hardest hit were apparently closed due to virus quarantines etc
