View Full Version : Interesting phenomenon from Monday

I found this radar loop from Monday. Aside from the ridiculous hook in the return and the purple debris ball as it moves through Moore, notice the fast-moving storm that overtakes the main cell from the southwest and is ingested into the storm. As soon as it gets that energy snack, it explodes into the monster. Also, if you look at the little clipper storm, you see the beginnings of an inflow notch on the SE flank of it. So it looks like the little guy was also starting to rotate before it got munched.

Is that Draper Lake it hits right at the end of its cycle? I thought it was odd how quickly the tornado died that day, but this is just what happened the day before when the tornado went over Arcadia Lake. That one later reformed, though.

Yes, that is Draper. This storm also re-formed (albeit in a weaker state) out close to Meeker.

I am a former radar tech for the USAF I was ATC but I know weather returns. Looks to me like the mesocyclone sucked in upper air from the smaller storm and created a greater updraft. When it passed over Draper cooler air at a low level lessened the affect.

If there is someone here that knows meterology please correct me if I am wrong.

You've pretty much got it, Flag.

And Jaun, that pic is ****ing bull****...you should NOT be openly posting that stuff here. Next time, use it as a link and put "disturbing tornado injury photo" tag on it.

That was a bit disturbing, but maybe we needed to see it.

Sorry if that offended anyone. It appeared on my facebook page this morning from Huffington Post. Seemed to fit the discussion of what a monster of a storm it was.

Here is the lady whose leg was pictured, and the story behind it:


http://i.huffpost.com/gen/1152524/thumbs/o-SUZANNE-HALEY-IMPALED-570.jpg

When Suzanne Haley was gravely injured in the Moore, Okla., tornado, she didn't panic. Instead, the teacher's aide tried to allay her first-graders' fears by asking them about the sparkly stickers and rubber stamps they were using on their end-of-year scrapbooks.

Haley, a first-year paraprofessional at Briarwood Elementary School, said she focused on her students even after the metal leg of a desk impaled her right calf.

She was trying to protect the children, who took cover under half-moon-shaped desks when the EF5 tornado, which killed at least 24 people and injured about 240, demolished their school Monday. She described the roof of the school blowing off and the walls falling inward, trapping and burying them in the classroom.

At first, Haley, a 35-year-old single mother of two, thought her leg was simply stuck under something heavy -- until her daughter, who attends Briarwood and was in her classroom, let out a loud scream.

Luckily, the desk leg hit her calf muscle instead of major nerves, bone or arteries, Haley said.

She managed to unscrew the desk leg from the desktop, all while calming her students and daughter. All the children escaped unharmed, she said.

"Suzanne is probably the most selfless person I know. She didn't even think twice to put her body over those children and put her life in danger," Haley's close friend, Michelle Allain, told HuffPost.

According to Haley, a handful of first responders came to the rescue, freeing her and her students from the rubble and administering an IV to her. She was going into shock, she recalled.

She was put in the bed of a truck with her leg stabilized by cinder blocks, and her rescuers initially took her to Moore Medical Center, only to find it leveled. They then drove five miles south to Norman Regional HealthPlex.

Once at the hospital, the teacher's aide underwent anesthesia before a surgeon used a saw to cut through the desk leg. "One of the last things I heard them say was 'hacksaw' before going under," Haley said.

Recovery should take about three months, Richard Kirkpatrick, the Norman Regional surgeon who treated her, told HuffPost. She'll be discharged Thursday, likely with a post-operative boot, and will have to use a walker or crutches.

"We've seen a lot of things and this is certainly unusual, since people don't usually come in with foreign objects still in them," Kirkpatrick said. Since the rescuers couldn't safely remove the impaling desk leg, he added, it "needed to be removed in surgery."

The surgeon said Haley was lucky that the metal object didn't go through any vital parts. "I'm optimistic she will basically have a full recovery," he said. "The muscle will heal as well, and we don't expect her to need lots of follow-up surgery. It's fortunate considering it was a graphic injury."

Following the tornado, he noted, he treated mostly broken bones and lacerations.

Haley said she knows she's lucky and feels love and support, especially from her friend, Allain, who has been at Haley's side since the accident. The two friends also lived through the EF5 tornado that struck Moore in 1999, one of dozens of twisters that killed 44 people across Oklahoma.

Allain said she knew from the 1999 experience that Monday's storm was also an EF5.

"This tornado wrapped and dropped from the sky so fast. I knew it was an F5 when I was watching TV. There's certain ways that things get twisted," she said. "I saw the tornado hit the school on the news, and that's when I knew I had to help [Haley]."

She took off from her home on the north side of Oklahoma City to get to Moore, dodging loose concrete, steel bars and back-to-back traffic. A trip that would normally take 30 minutes, she said, took her four hours.

"I was driving on the highway about 100 mph to get to Moore with my lights flashing, honking and being psychotic," Allain recalled. "Every cop I saw tried to make me turn around. I said, 'You're not God. You're not going to keep me from my friend, who was one of the teachers who was hurt.' I could have driven to Dallas and then some."

Allain noted that Haley's students have come to visit, one giving the teacher's aide an angel necklace and a big hug.

"People wrote on my Facebook wall saying, 'I pray to God that's the type of teacher my kids have -- one who treats my children the way I'd treat my children,'" Allain said.

HOW TO HELP:

Haley told HuffPost that any donations she receives will go toward medical expenses and the purchase of a new vehicle. Hers was found crushed outside the school. "I am a single mother, and unfortunately money is already tight as it is," she said.

A fund has been set up in Haley's name. Donations may be transfered on PayPal.com, directed to the email address: [email protected]

The picture is disturbing, but the woman is a hero.

Anyway, what amazes me about the radar loop is that when the hook hits I-44, the inflow is incredible.

I have a question for you weather guys, if the storm hadn't hit Draper, would it have kept going? I know it would eventually die out, but when I was watching it live, it seemed like as soon as it got to Draper, the tornado stalled, then collapsed. Is there a correlation, or was it just a normal occurrence and the lake had nothing to do with the tornado dying?

He said the cooler air over the lake stalled it.

I guess since water does not hold/release heat the way the ground does, it interrupts the cycle of warmed air rising to feed the storm. Surprised that a smallish lake like Draper could have that effect, but I guess with all the rain this year Draper has swollen some. As big as that tornado was I'd have thought it would push right over that lake and keep churning.

Fickle beasts, for sure.

I would have expected it to keep grinding, too. The Shawnee storm on Sunday sat over Shawnee Reservoir for several minutes and strengthened before it moved on and killed two people. Bottom line is that something killed the inflow and weakened the updraft temporarily. I'm guessing that the water temp in Draper is lower than usual as well, since the spring was so cool for so long. Maybe it was the second fast-mover that comes up over Blanchard?

Water makes no difference...it was just when the storm ran out of gas...nothing more

From what I've gathered, the Joplin tornado was similarly fueled by the inflow of a system that came out of nw Oklahoma and met up with one coming out of Kansas. It was fueled incredibly fast into an F5.

Thanks for sharing that vid clip, Prrriiide. That is interesting.

I'm also interested in further debate about storms passing over small lakes. I know some people who live just north of Lake Texoma claim that the lake affects the local weather (lower rainfall and less intense strong storms than surrounding areas), but I haven't heard any of them explain exactly why they believe that.

In the interest of starting drama on the board, yes I am! ;)

It has to be a decent sized body of water to effect a storm of this size...and Draper doesn't qualify. Now if the storm had run into Lake Michigan...
