burrel2 Posted April 13, 2020 I resisted the urge to drive to Seneca today even though it’s less than 10 miles from my house. Figure I’ll check it out in a few days after emergency services have finished what they need to do. i did drive to the pharmacy today and it appears the tornado made it to approximately 12 mile recreation area as there were dozens of trees down/snapped right there with a tornado look to them. If you plot the points from there to the Seneca damage the tornado path line intersects my house. Luckily it appears to have lifted right around the 12 mile rec area which is about 1.5 miles before reaching home. Whew! Explains the large rigid insulation panel fragments all over my property though as they must have been carried straight here from the borg plant and fell out when the tornado lifted. I didn’t see those panels/fragments anywhere else on my drive. Quote Share this post Link to post Share on other sites

brianc33710 Posted April 14, 2020 I haven't been able to keep up today. Did the SPC expand the moderate risk N & E? Much of what happened later was in the "enhanced" risk. Quote Share this post Link to post Share on other sites

JasonOH Posted April 14, 2020 Bassfield is a prelim EF4. The trailing tornado is prelim EF3. (Thanks to Andy for the correction. I got my counties all messed up) 2 Quote Share this post Link to post Share on other sites

The first tornado from the lead supercell (same that produced the Bassfield EF4) is EF2 (in Walthall County). Just wanted to clarify since this all is quite confusing indeed. 1 Quote Share this post Link to post Share on other sites

MUWX Posted April 14, 2020 The only thing holding that storm back is the quality of the construction. The vegetation damage is very high end. 2 Quote Share this post Link to post Share on other sites
DanLarsen34 Posted April 14, 2020 1 minute ago, MUWX said: The only thing holding that storm back is the quality of the construction. The vegetation damage is very high end. Had the same thought, but lest we forget that tornadoes can still occasionally get an EF-5 rating based off of vegetation damage. It’s rare, but there is precedent for it if the other contextual evidence supports such a rating. Quote Share this post Link to post Share on other sites
DanLarsen34 Posted April 14, 2020 I know we discussed this earlier, but it bears repeating: this was a major outbreak. There’s a good chance we had 60-100 tornadoes in a 24 hour period, with several intense ones. It’s even possible we end up with 3-6 violent tornadoes when all is set and done. it may not have been the multiple discrete cell outbreak some were expecting, but we still ended up having one of the higher-end tornado events of the past 20-30 years yesterday. 3 Quote Share this post Link to post Share on other sites

Wmsptwx Posted April 14, 2020 Seems like a lot of 170 type Ef 4s I believe same as Tenn tornado earlier this year and the Beauregard tornado of 2019. Quote Share this post Link to post Share on other sites
Buckeye05 Posted April 14, 2020 2 hours ago, DanLarsen34 said: This is one of the cleanest sweeps I've ever seen, and the best candidate for EF5 I've seen in years. Notice how not only is the foundation is clean of debris, the whole area is clean of debris, and there is no recognizable directional debris pattern. That is indicative of a remarkably violent tornado. Also note that all plumbing fixtures are all completely sheared off and missing as well. Most importantly, there is a close up video of the foundation perimeter on youtube, and not only is the house well-anchored, but the anchor bolts are bent flat against the slab from the force of the walls being violently ripped away. The only thing keeping me from saying with certainty that this is EF5 damage, is that there is some vegetation on the property that is suspiciously untouched, with quite a few leaves remaining. However, I'm wondering if these non-defoliated limbs and trees blew around the back side of the circulation from an area that wasn't affected by as violent of winds. Also not seeing any crazy grass scouring, but in any case, this is a candidate. We'll just have to see. 1 Quote Share this post Link to post Share on other sites
Windspeed Posted April 14, 2020 RE: Discrete, semi-discrete and QLCS cells.. They can all produce violent tornadoes when you have intense parameters like CAPE and bulk shear. There was a period of time yesterday that when it appeared convection was going to go more linear that many, myself included, imagined the event was going to bust. Some to the point of it's going to be a flop mentality. Yet clearly beyond the two main discretes that produced the preliminary EF3 and EF4 twisters in MS, we are going to be presented with numerous violent tornadoes that were produced by quasi-linear cells. We have to realize or change thinking that just because an event doesn't produce the classic string pearls or 5-10 long-tracking individual discretes, it is somehow less of an event. This one in particular wasn't just an outbreak, but a very infamously memorable one. The parameters were just nuts and what we got was indicative of them. 5 Quote Share this post Link to post Share on other sites

This wasn't just an outbreak, but a very infamously memorable one. The parameters were just nuts and what we got was indicative of them. Good point. I've noticed that in certain setups, storm mode doesn't effect the overall outcome much. When conditions are favorable enough, semi-discrete and QLCS structures can spit out numerous strong tornadoes, and even long-tracked ones. Strong QLCS tornadoes are more common than I think many realize. This seems to be especially true with Dixie severe events. 2 Quote Share this post Link to post Share on other sites
