Very thorough, scientific explanation and playback of events. I was expecting just a loop of the radar. But you actually had the data and program to show everything the meteorologists saw and even look at a vertical image of the tornado itself. Thanks for this man. You earned a sub.
@@carlahead5072 Around Oklahoma City they're too common. That region has seen more than 5 F5 tornados in only 5 years. 2 of them took almost identical paths through Moore; one had the highest wind speeds ever recorded and within days, the largest tornado in history touched down and just missed a nearby town (El Reno). When I saw on video how fast the Joplin EF5 started, then grew, I could barely get my jaw off the floor.
That's an isolated supercell for you. Most dangerous days are where supercells like this are allowed to develop in "loaded gun" settings with absolutely nothing blocking it's path or inflow.
Aside from this storm; the EF5 tornado that hit Joplin, Missouri on May 22nd, 2011 also developed from a storm which wasn't all that impressive on radar, but it turned into a disaster of nightmarish proportions.
That 'little rain shower' was rotating as soon as it fired. All of these had big time potential as soon as the blips popped up that day, it was all about which one would produce - or would they all. Extreme high risk that day.
This was very much needed as I've been studying the storm and can pretty much tell how the twister looked throughout its life and knowing that I can better see just how well this radar is compared to the other older one used that only had one line as it took its reading. This storm is just terrifying. A perfectly spawned stovepipe and as soon as it began grinding through residential areas was when it went into the barrel and then a monster wedge with so much debris kicking out the front and hooking to the south east and then flowing back into it amd just spit out all over filling the air with that lumber smell. Everytime I smell that smell it makes me nauseous as it instantly reminds me of looking out west to see a light haze to the south west then, blackness and debris thousands of feet up. Telephone poles. Cars. Car parts. Large sections of homes. Nothing could prepare anybody for the aftermath. God bless all the people who had been effected by this.
@@hawkeye2958another issue might be building code, out east the houses aren’t built very well Take the Hendersonville tornado from last December for example, an extremely violent tornado completely destroys houses but they were so poorly constructed the NWS can only give an EF2 rating
I believe there has been many ef5s since but they dont seem to want to give ef5 ratings as easily anymore, one example would be the mayfield tornado, extremely strong couplet, even much more than this one but luckily it stayed over open land when it was at its strongest near bremen. Its all about the construction quality thats stopping us from hearing about an ef5 rating
That’s not Lake Thunderbird, that’s east of Norman on highway 9. What you pointed at was Lake Stanley Draper. But otherwise very cool and good explanation
The only radar data available for Jarrell was taken around 100 miles away, NEXRAD data at that time wasn't great. Joplin is easy to do, as radar imagery was available for download.
On the storm motion issue, you can just go back a frame or two and decipher the direction and speed for your motion. Gr2A actually has a feature built in to do this.
I live in Oklahoma and this was one of the worst days for us. I was only in kindergarten but when we live in Stephens county they had us on lockdown till our parents came and once we got home we saw it on tv and I bursted into tears it was so scary.But I mean its Oklahoma u font know what will happen.
While the disaster was extremely scary; what balances it out is the sense of community that followed in the immediate aftermath. For those who are not familiar with it; this is a phenomenon known as the Oklahoma Standard. This term was first coined in the immediate aftermath of the Oklahoma City bombing in 1995 and was meant to reference how average everyday citizens dropped whatever it was they were doing and raced to the site of the bombing to help the first responders with rescue efforts. With regards to the tornadoes that struck Moore, Oklahoma (May 3rd, 1999 and May 20th, 2013) it was meant to reference how average everyday citizens who were not injured by the storm helped out the first responders by loading the injured into the beds of pickup trucks or the backs of SUVs and minivans and getting them to hospitals throughout Oklahoma City. Moore Medical Center had been struck and knocked out by the storm; thus rendering it unable to treat the injured.
It’s crazy how people just 1 mile west of that inflow line are in the clear but if you’re directly in that line and east of it you’re under extreme duress. Thanks for this very informative video. Weather is fascinating.
I once watched a tornado spawn directly over Hilton Head, SC. I was miles away on another island and had a good cross section view. The tornado formed at the leading edge of the thunderstorm and bizarrely had a well defined horn like protrusion from the top of the storm as well - like at a 30° off the horizontal upwards and above it.
This information is incredibly valuable, thank you for posting this when you did. There is an unusually violent day tomorrow in North Texas, and this information is super useful to find out when to really watch out for supercellular activity that leads to these unfortunate kind of violent tornadoes. Appreciate the upload.
The 2013 Moore tornado was every chaser’s nightmare. An incredibly large and destructive tornado impacting a heavily populated area is every weather enthusiasts worst nightmare.
Not really. No storm chaser wants tornados to hit a heavily populated area, and the tornado had quite low visability making it more dangerous to chase and less enjoyable as you can’t pick out what’s going on. For those who like taking photos, watching, picking out structure or many other reasons that storm chasers chase it was a nightmare. The only ones who would’ve enjoyed it are the adrenaline junkies which are very rare and are by far a minority. For many storm chasers a perfect tornado/ storm would be one out of a populated are ie middle of nowhere, that does virtually no damage, has a clear funnel. This storm was a HP supercell which are more dangerous than classic or LP and less visible. This really wasn’t a storm that anyone would’ve wanted.
@@hannahreid1549 Absolutely. A prime example of this aside from the Moore, Oklahoma tornado on May 20th, 2013 would be the Joplin, Missouri tornado on May 22nd, 2011. The Joplin tornado was an absolute nightmare for not only the residents of Joplin but also the storm chasers who were tracking the storm. Someone on Quora asked why the 2011 Joplin tornado was much more deadly than the 2013 Moore tornado; it comes down to a few understandable reasons: 1.) The Joplin tornado formed too quickly for the National Weather Service office in Springfield, Missouri to issue a Tornado Emergency for Joplin; but they were able to issue a Tornado Warning for both Jasper County and Newton County. 2.) The tornado formed right outside of and went through a densely populated area. 3.) The tornado was hidden in very heavy rain which made it difficult to see. 4.) The residents of Joplin weren't too concerned when the sirens were first sounded and assumed that there wasn't anything for them to become too concerned about. 6.) Prior to May 22nd, 2011 Joplin hadn't been hit by a significant tornado since May 3rd, 1971. 7.) When the tornado sirens in Joplin were first sounded at 5:17 PM Central Daylight Time it gave the residents of the city seventeen minutes to take shelter. By the time the tornado sirens began wailing a second time at 5:34 PM Central Daylight Time it was too late to do anything because the tornado was already on the ground and moving rapidly towards Joplin. Just seven minutes later at 5:41 PM the tornado enters the southwest side of Joplin and unleashes Hell on Earth. By stark contrast the residents of Moore, Oklahoma are extremely weatherwise and aware of how bad tornadoes can get because their city has become practically synonymous with large, long-track, violent and destructive tornadoes. When the National Weather Service office in Norman, Oklahoma issued a Tornado Watch for much of central Oklahoma at 1:10 PM Central Daylight Time on May 20th, 2013 the three major TV stations in Oklahoma City metro area (NBC affiliate KFOR Channel 4, ABC affiliate KOCO Channel 5 and CBS affiliate KWTV Channel 9) immediately suspended regular programming and went into wall-to-wall coverage of the weather. They stayed on top of the tornado from the time it touched down near Newcastle at 2:56 PM until the time it dissipated at 3:35 PM.
@10:29 I don't know if anyone else noticed or commented this. Right before you say the tornado disapated, you can see a smaller cell try to hook south west of that one and it merges with the monster tornado.
And with 300mph winds...it would have been catastrophic. I forgot which highway it was but there was a highway that wad backed up and it was in the path of the el reno tornado. Thankfully the tornado died before reaching said highway, if so it would have killed over 500 people, making it the worst tornado disaster in modern US history
@@nickdavis965 it was several highways that were jammed with traffic. The local news told people to flee south in their vehicles. The worst possible advice that almost killed a ton of people. There are only a couple places to cross the river south of okc and el reno. Which is why traffic was backed up everywhere. That storm could have easily spawned more tornadoes as people tried to flee in their cars.
@@johnshottie4415 The meteorologist responsible for that snafu is Mike Morgan; the chief meteorologist for Oklahoma City's NBC affiliate KFOR Channel 4. His fellow meteorologists Damon Lane and Gary England (the chief meteorologists for Oklahoma City's ABC affiliate KOCO Channel 5 and CBS affiliate KWTV Channel 9, respectively) gave advice that would have actually saved lives.
This day was crazy I ran away from it, I was working in Moore on a very sunny day then I heard sirens I was so close to the tornado after that storm I became a amateur meteorologist
I agree with dmc12guage . Thank you for the information and what to look for if you have your own weather app . I have radar now and upgraded so I can see the velocity part as well as everything else but had no clue on how to read it , this helps allot . I have. Question , rather I want your opinion since you seem like you can hold an adult conversation ( very rare ) so my question : Do you think that these storm/tornado chasers are collecting more data then what you already have ? Like do u think it is necessary for them to do it or do you have all the data you need from Doppler and velocity ? I have seen many risk their lives and some lose their lives doing this and when asked why they say to gather more data so they understand how they work to predict their behavior and what paths they may take . Like I watch allot of these and have done all of the research that makes sense to me and it seams like these are completely unpredictable because there are so many different factors . I’m interested what your answer is ,or anyone’s answer who reads this . Thanks so much
I’ve used GRLevel 2 analyst for years and btw this guy did nothing wrong! The tornado and updraft is tilted in the real world. Tornados only appear straight because the wall cloud tilts and the updraft is tilted tornados usually lean into the direction of travel NE or E. If the tornado and updraft was not tilted it literally wouldn’t be possible to have a RFB
Mike Beard I’m pretty sure it is a dry line... which of course is just a different type of boundary and would essentially serve the same role in the formation of the supercells/tornado. The dry line in that area of the country causes all sorts of problems with tornadic supercells. The Jarrell TX tornado was created in a low shear environment when a cold front intersected the dry line and a gravity wave from Arkansas the previous night hit that intersection point.
Radar indicated is something we didnt hear decades ago. Ive always been weather nerd and ive watched radar advance and always keep my eye on the radar during supercell season.
5:09 I didn't know a purple TVS existed until now... Well, when I'm tracking storms on GR2 Analyst I'll definitely be on the lookout for that. The most I've witnessed is a red TVS, and that was with one of the Texas wedges in April/May.
They are pretty rare if you use the default settings in the program. You can manually modify those for the conditions at hand though (lower-topped or low-instability events, Dixie Alley events, etc).
I still can't believe how people are so ignorant to weather/storms. You could go inside a store in Texas and yell "tornado warning" and people think you're nuts or probably start laughing.
Minor nitpick: the tornado that was 2.6 miles wide was the one that hit El Reno, Oklahoma on May 31st, 2013. The tornado that hit Moore, Oklahoma on May 20th, 2013 was only three-quarters of a mile wide.
Climate Change, the way The Moore Ef5 develop so quick and a week in 1/2 later the El Reno Tornado became the biggest beast of all time with the unpredictable turns, speed and size is all due to climate change, very scary and in a quick pace of time
Can you do the April 28, 2002 EF5 (F4 as rated in 2002) Tornado in La Plata, Maryland? It’s rare we even get tornados and they said that was a Kansas/Oklahoma type storm for us. It would be cool to see that one broken down.
I remember watching this tornado was a distance away, the storm was moving north east. I looked up at the clouds and I just see the newly formed clouds literally RUSHING dew north northwest into that storm. And yes I was safe enough way.
Love the presentation! Your explanation was extremely precise! Say, where did you find this past radar information? I've searched everywhere online and I cannot find any loops from past dates.
Do you think using the correlation coefficient package would have defined the debris ball a little more clearly? Great video. I appreciate the analysis.
at 4:08 it looks like the parent supercell "ate" a thundershower to its south. did that have anything to do with the rapid intensification of the tornado?
I see you are using neowwather. Are you in Ohio? I'm asking because I'm wanting to learn radar and i have been studying quite often. I have radar omega and i have learned alot but i have alot more to learn. I love in Southern Ohio one hour east of cincinnati in a country area. I don't like living in the city. Abreast I'm fascinated with weather radar since i was around 8 yrs old. I guess what I'm asking is, will you help me or do you know if any site i can go to study and learn the advanced things about radar. Any information will be and is very appreciated thank you God bless...
What version of GR2Analyst are you using? I noticed you were able to draw lines indicating outflow boundaries and rotation to viewers. Something im not able to do with the current version i have

Its oklahoma u never know
I live in Wichita Falls TX and I remember getting hit by the supercell Over us, their was like 70 MPH winds and hail
In indiana, it starts light rain showers then starts being windy and heavy rain, it destroyed a gas station under construction, lucky didnt explode.
Amazing isn't it.
That's an isolated supercell for you. Most dangerous days are where supercells like this are allowed to develop in "loaded gun" settings with absolutely nothing blocking it's path or inflow.
Who would have thought an EF5 tornado would develop from such a small rainstorm. Incredible!

When you get six EF5 tornadoes on one day in 2011, but then zero EF5s (supposedly) for the last decade or more, then maybe the rating system sucks.

Did it develop in a hurry?
Yes. Very
That other cell in Stephens county was the scarier looking storm for a min then the one at moore just exploded.
This is a GREAT video!
Your Dual Polarized Radar scan will show the debris ball way better.
grlevel 2 Analyst is the program.
The second I saw the little rainstorms on the radar, I pictured the scene in Into the Storm where it starts raining at graduation and a tornado comes.
I remember watching this tornado was a distance away, the storm was moving north east.
I looked up at the clouds and I just see the newly formed clouds literally RUSHING dew north northwest into that storm.
And yes I was safe enough way.
No clue what you just wrote.
Great video!
What program did you use to see the radar like that?
It's called GR2A... It's a Gibson Ridge product
@@Neoweather okay
Thanks for this!
Love the presentation! Your explanation was extremely precise! Say, where did you find this past radar information? I've searched everywhere online and I cannot find any loops from past dates.
You can download the data from the NWS website: www.ncdc.noaa.gov/nexradinv/
Do you think using the correlation coefficient package would have defined the debris ball a little more clearly? Great video. I appreciate the analysis.
Geez, a small rain cloud caused destruction eventually. Weather is crazy
The terrain on map where the hills end and Moore thunderstorm converted to meso looks like the lift mechanism
That thing became a fricking monster so fast. It still shocks me every time I see it.
that tornado cost damage
Great video man love it
Who saw the face at 5:15
back here 2 years later and how did i see that
Storms are scary!
Best example of a hook echo ever.
What program(s) are you using?
GR2Analyst, $250 from www.grlevelx.com/
Great info thanks for sharing
at 4:08 it looks like the parent supercell "ate" a thundershower to its south. did that have anything to do with the rapid intensification of the tornado?
Is that little, round, “ground zero” lookin thing east of Moore the actual radar location?
Sorry for such a late comment, Loved the video and analysis. One question. What placefile did you use to get road labels from that?? Thanks!
What app is this
6:33 looks like a Bigfoot skull staring down at the ground! When will we realize the only mostly safe place to build... is underground.
Radar en casos de tornados es verdad
I like how suspense music started playing when it grew to EF 2
Cause it’s so quick. These things intensify so quick. If it’s that powerful from the start it’s probably gonna keep going.
I remember watching it live. I was only around 30-40 minutes away
By any change we’re you in Ardmore?
5:13, look at the face in the radar on the back of the storm. I dont really believe in that sort of thing but that image is uncanny.
“Yeah,” a face... Lol
i saw lighting and then BOOM!. a tornado🌀
Thats just one spinning cloud , low precipitation is an understatement
The Jarrell tornado could beat up the Moore tornado.
What software is this???
GR2A
I see you are using neowwather. Are you in Ohio? I'm asking because I'm wanting to learn radar and i have been studying quite often. I have radar omega and i have learned alot but i have alot more to learn. I love in Southern Ohio one hour east of cincinnati in a country area. I don't like living in the city. Abreast I'm fascinated with weather radar since i was around 8 yrs old. I guess what I'm asking is, will you help me or do you know if any site i can go to study and learn the advanced things about radar. Any information will be and is very appreciated thank you God bless...
What version of GR2Analyst are you using? I noticed you were able to draw lines indicating outflow boundaries and rotation to viewers. Something im not able to do with the current version i have
do an el reno video
Would that line that developed be considered a squall line?
Neoweather What program you use, that allows you to draw?
abver09 GRlevel2 Analyst
Well Done!
What radar software do you use?
What are you using for radar?
Anyone know this color table?
Just wait 4 days...
Where is it charrlot
do you still have the color table for that for the BR.
+SevereWeather WxAnalysis Unfortunately I no longer have this file. :-( - Mark S.
PS: Sorry for the late reply!
How can I get volume explorer?
I'm so excited about this one
