5/19/10 REPORTS OK

[Ben_Jacobi]

Wow! Great reports everyone. I chased with Jason Brock in OK. Our original target area was Fredrick, OK. We were hoping there would be something in the cu field, but nothing happened. So we headed north to Clinton, OK hoping to beat the storm. It passed over Taloga and we headed to Watonga, OK and chased it almost to Guthrie. Never saw a touchdown, but we saw some awesome structure and a few fuinnels.

Chase report on my blog.

Hope it's not too late for a quick log.

Chased the Watonga /Hennessey/ Kingfisher / Stillwater storm cells, caught the cone everyone saw near Hennessey and had fun a little later on a road that was marked as being paved on my GPS but was little more than sandy gravel in reality.

I was also on the Kingfisher->Payne county OK storm. Documented several tornadoes, including the large tornado NW of Hennessey, and a couple of tornadoes east of I-35 along Hwy 51.

Tracked the Wynnewood storm from its inception and followed it several hours after dark into Ada, Ok. Actually got a pretty good persepective west of I-35 where we encountered trees down in the road and a house damaged and had to reroute around the damage. We could see power flashes from that point and a rapidly rotating wall cloud. I was able to catch some photos earlier in the day before light became a problem.

If you are wondering how one can fail at this chase my log is now posted.

Got on the storm that tracked south of OKC...it may have produced as we were in the bears cage. Gotta love the amazing terrain south of OKC [not]

The easiest tornado intercept I have EVER had in my life. It was just like the tornado had an appointment with me, and met me at the exact location at the exact time!

My wife and I are both Skywarn. We drove up from Dallas as SOON as I got off work at 6pm. Drove straight up I35. Could not make it to the Stillwater storms, so we started watching the storm farthest South that was headed to Wynnewood. Driving exactly the speedlimit (no kidding), the storm literally MET us at I35. All we did was pull off the highway exit, sit there for 10 minutes and a tornado formed RIGHT in front of us! Slow moving as can be. HD Video at YouTube:

Amazing day early for us (College of Dupage) since we watched the Leedey storm from a TCU to tornado in a field just to the north of our location! After the tornado, we got back into position, but with the chaser convergence and the storm becoming rainwrapped, we drove south for more potential storm development. We eventually chased the Noble HP, and were in the notch, but never did see a tornado. Congrats to those who observed tornadoes with the Hennessey and Wynnewood storms, they sure looked good from a far visually!

Sorry post late .

As the storm went Tornado Warned , I checked in with Murray County E.O.C. and headed west . I stopped at Midway Hill ( between Davis and Sulphur ) and watched a area of rotation in the rain free base . After a few minutes a multi-vortex tornado formed to my northwest ( the Rubby Rd. and I-35 area ) . Soon the tornado went rain rapped and I headed west to Sunshine Rd. After about 4 mile's , I watched what looked like a Stovepipe tornado rapped in rain to my north with a few power flashes . E.O.C. ask that we all move east , so I headed east then, northeast on the Chickasaw Turnpike . About 5 mile's past the pay booth , I watched a cone funnel to my north for a few minute's till a group of chaser's stopped . I pulled off at the Roff exit and joined a group of Roff Firemen watching a series of power flashes a few miles north of the turn pike . With the rain moving in I dropped south into town and took cover as a brief burst of 1" hail fell. As I got ready to move the In-flow stopped and I got hammered by 60 mph wind from the west that lasted a good 5 minute's. At that time chase was over for me and I returned to Sulphur . After getting to town I stopped to talk to a fellow iMap live streamer Paul from Fla. and the Denmark Chase Team.

EF Rating : EF1
Tornado Track : started in Garvin co. and was on ground for most of Murray co.
Tornado Wideth : widest point 200 yards wide.
Damage : 20 home's.
Destroyed : 1 home
Hurt : 0

Having finally had a few hours to look over video from the season I found I captured another Large Tornado about 45 minutes after the Wynnewood Multi-Vortex Tornado. It was a sparsely populated area so I was lucky to get one power flash, even luckier to have had the camera trained on that spot. These were video grabs I captured.

I adjusted the contrast on this image to give a better view of the tornado.

Sorry for the delayed report on here. I had a great day chasing and was able to snag at least 4 tornadoes on camera. Here are a couple of them....

 

[Matt Gingery]

I finally edited my compilation of events of my 5-19-10 chase day in Kingfisher County, Oklahoma. I chased without any data at all, and had the help of a local on camera meteorologist to give me real time data i.e. temperature spreads, bulk shear, and composite index variables. By the time I arrived in the El Reno area I spotted the tower that I drove 5 hrs to chase. Timing was perfect and execution was exceptional on a day without radar or instrumentation.

5/19/2010

Long story short my first high-risk chase day. I left Dallas around 3:00 p.m. and arrived at Paul's Valley/I-35 I believe at 5:00 p.m. I got inpatient and left for the cell that was going to hit Purcell. I arrived around 6:00 p.m., In the midst of the chase I took the wrong turn (SR 74) and core punched receiving golf-ball size to my mint Honda Civic . Afterwards I was able to take some pictures looking northeast. I pulled off the Purcell cell and shot back on I-35 to catch the cell in my original target area. I arrived at the time spotters were reporting multi-vortex tornado. Never saw the tornado and didn't get in good position to view the storm. Nonetheless I was happy with the Wynnewood storm structure

Dover, Oklahoma Tornado

I finally posted my video of the Dover, Oklahoma Tornado:



2010 May 19 Dover, Oklahoma Tornado - Direct YouTube link

SHORT: Gene Rhoden and I chased the Leedey-Dover-Guthrie, OK tornadic supercell and then Purcell-Lexington supercell towards sunset. Saw brief tornadoes near Loyal and another rain-wrapped tornado near Dover.

LONG: Gene Rhoden and I first observed the Leedey-Dover-Guthrie, OK tornadic supercell when it was crossing Roman Nose State Park north of Watonga. The storm had a very low base, looked "cold," and had outflow problems. We lost radar Verizon data at this point, but the storm visually looked HP.

We drove east out of Hitchcock and parked just west of Loyal, OK. There the supercell developed a rapidly rotating wall cloud just to our west. I saw a brief needle funnel touchdown out the back window as we drove east out of Loyal and then the meso wrapped in rain curtains while we were parked next to Rich Thompson/Roger Edwards a few miles east of Loyal.

We saw the rope stage of a rain wrapped tornado several miles to our WSW when we were parked on E0730 RD about 2 miles southeast of Dover.

We next saw a rotating wall cloud to our WNW, but no tornado while parked a few miles west of Guthrie. At this point, the storm appeared to be gusting out, so we decided to drop south after a new storm which had a tornado warning for Norman.

We intercepted this supercell from the southwest side near Purcell and followed it east a few miles east of the Lexington, OK prison on OK39. The storm had serious outflow problems and began to line out. We saw one last strongly rotating, but undercut meso to our northeast as the sun set.

Neither of these ever had intense mesos (that we could see on radar) and both had outflow problems.

The chaser storm of the day was the Hennessey-Stillwater storm. The warm front appeared to bow-northeastward and the storm was able to ride warm front for a few hours. We debated whether or not to intercept this storm, but as of 22Z OK mesonet and Visible satellite images indicated it would move into cool, stable air and die. Wrong! VORTEX2 was on the Leedey-Dover-Guthrie storm and perhaps their results will explain why this storm struggled compared to the eastern supercell.

Meanwhile, the Wynnewood, OK tornadic supercell continued to chug along as I type this. Radar indicates it is a cyclic tornadic supercell. Too bad it occurred after mainly dark and in the trees.
