Good day all,
Below is my detailed chase log for this day... Again - God Bless the victims, including great chase comrads of mine, Tim & Paul Samaras, and Carl Young. Pictures are below.
Above: Wedge tornado approaching El Reno, Oklahoma on May 31, 2013. This view is looking WSW from a cemetary in El Reno and the tornado is a few miles away.

Above: Wedge tornado - Near El Reno, Oklahoma on May 31, 2013. This tornado is rapidly intensifying and part of as larger circulation that will eventually become a 2.6 mile wide EF-5 tornado with 296+ MPH winds.
Above: Yes - I'm scared - And close to being killed in this picture. I am trying to race southward on Highway 81 (south of El Reno, Oklahoma) to get out of the outer circulation of a rapidly intensifying EF-5 tornado that would quickly become 2.6 miles wide and pack winds near 300 miles per hour. I am in the 100+ Knots inflow and looking back, the massive tornado looms behind me in the extreme wide-angle shot. Holding the camera (GoPro 3) was almost impossible, and the raindrops caused abrasive-like scrapes and cuts on my wrist. Scientists Tim Samaras, Paul Samaras, and Carl Young were behind me somewhere and lost their lives in the tornado. This is May 31, 2013 and the view is looking N to NNW.
Above: Wedge tornado moving away and to the east of Highway 81 and southeast El Reno, Oklahoma on May 31, 2013. This is at the point where the EF-5 tornado grew from a mile wide to 2.6 miles wide in 30 seconds! Most likely, this WEDGE tornado might be a "sub" vortex rotating around the large circulation! The actual left "edge" of the 2.6 mile-wide tornado is far out-of-frame to the left and not visible in this picture. Windspeeds were near 296 MPH at this point!
Above: Quick shot of the flooding in suburban Oklahoma City late on the evening of May 31, 2013 ... Note the cars floating just upper-right of the center near the yellow hydrant. Trees are down and flash floods are ocurring, with rushing water in the streets! All this in addition to record-breaking tornadoes.
-- Storm Details --
1). May 31, 6:00 PM - Interception, observation, and penetration of an extremely severe and violent tornadic thunderstorm near and to the south of El Reno, Oklahoma in Canadian County. The storm was a violent classic / HP cyclic supercell storm, and produced at least three tornadoes (most of these being mile-wide multi-vortex / wedge type). The storm also contained grapefruit sized hail and 100 MPH winds in addition to heavy rains and tornadoes. The main core was avoided. Conditions encountered during this storm were winds over 100 MPH (tornadic inflow and RFD), frequent lightning with close hits, hail to baseball sized, and extremely heavy (horizontal) rains. The storm caused damage and deaths in El Reno. The large tornadoes were observed with this cyclic supercell, along with a very impressive striated updraft, wall cloud, inflow bands, RFD clear-slot, and supercell structure. The tornadoes were all wedge tornadoes / multi vortex, a mile wide in some cases. The outer circulation of the third wedge tornado (during its development stages) passed very close to, if not over, the chase vehicle (nearly blowing it off the road). Other storm chasers had their vehicles destroyed from this storm. Conditions causing the storms were surface heating, low pressure area, a dryline, stationary frontal boundary, and strong upper trough. A 2013 Kia Sportage was used to chase the storms. Documentation was digital stills, audio, and HD video. A PDS (particularly dangerous situation) tornado watch was also valid for the area until 12 AM CDT.
2). May 31, 7:30 PM - Observation and penetration of another very severe and tornadic thunderstorm from near Mustang, OK in Canadian County and eastward to Will Rogers International Airport in Oklahoma County along State Road 152. The storm was an HP supercell storm, and took a direct hit on the town of Mustang. While in traffic, with people panicking, a car struck me in the middle turning lane damaging my front passenger door and wheel, destroying the tire. After that, the other motorist left and I was forced to retreat behind a church / gas station before the storm hit. I never saw the person who cut in front of me again. The vehicle could only do 20 MPH after quickly changing the spare tire. A tornadic circulation passed over my vicinity, and had gusts near 80 MPH with flying debris and power poles / signs down. This HP supercell evolved into a very large cluster of severe thunderstorms. Other conditions encountered were 80 MPH winds, hail to golfball sized, frequent lightning, and torrential rains. I had to "limp" to the airport to take shelter during the storm in their parking garage. After finding out I could not get any help from their car rental facility (power out and not same company / franchise), I had to hobble 10 miles to a motel off I-44 in heavy rains, flash flooding (cars were floating in rushing water in some streets), and hail to golfball sized. The storm ended after arriving at the motel off I-44 and Penn in NE Oklahoma City. Many trees down, power outages, and flash flooding were observed with this storm. Conditions causing the storms were surface heating, low pressure area, a stationary frontal boundary, and strong upper trough. A 2013 Kia Sportage was used to chase the storms and sustained damage (from the accident in Mustang). Documentation was digital stills and HD video. A tornado watch was also valid for the area until 12 AM CDT.
-- Summary --
May 31 was the final chase day of this expedition, and certainly was not for the faint of heart. At least 4 tornadoes were observed in SW Oklahoma, with 3 of them significant (wedge tornadoes), and with another toll on human life and property. I left Wichita along Highway 400 to I-35 south after doing a thorough forecast, with the primary target area being in the general vicinity of El Reno, Oklahoma. I continued down I-35 to Guthrie, to finally fix the slow flat tire, and continued to Edmunds to look at more data, get a quick lunch, and start heading west around the OKC area along Edmund Road to Highway 3, then eventually Highway 81 into the "target" city of El Reno, where I stopped. Many chasers were in El Reno, including Howie Bluestein, Melanie Metz, Bill Hark, Dan Robinson, Mark Robinson, just to name a few. The SPC was volatile in their outlooks, with a moderate risk in place, and probabilities of tornadoes at 15% hatched, wind at 30% hatched, and hail at a staggering 60% hatched. A surface frontal boundary intersected the dryline west of El Reno, with dewpoints in the upper 70's! Mesoscale discussion 907 and subsequent PDS (particularly dangerous situation) tornado watch box 262, valid until 12 AM CDT. Supercell storms (and strong wedge tornadoes) were intercepted west and through El Reno, basically around I-40 and Highway 81.
At one point, a developing multi vortex tornado developed nearly on TOP of me while struggling south on Highway 81. I continued east towards Mustang on State Road 152. This is where the traffic was very bad, and people were running around and panicking in their vehicles. I decided to turn around, as another supercell was rapidly intensifying and moving ESE towards Mustang. In the middle turning lane, moving at about 20 MPH to find a good place to make a left turn (with bumper to bumper traffic in the right 2 lanes), BANG! Someone pulls to the left out of the traffic jam and hits me, blowing out my front passenger tire and causing damage to the door and passenger side of the vehicle. I stopped, but looked back and could not see who hit me. I pulled off (with the broken wheel dragging), and went left into the backside of a gas station / church. I scurried in 70 MPH winds to replace the tire with the spare, but as I drove again, the right wheel was clanking and I could not go more than 20 MPH. At this point power went out, powerlines fell, and NO one was on the roadways. I saw an intense swirling of debris across the roadway with rotating clouds and rain-wrap all around (possibly the 4th tornado).
Heavy rains, hail to golfball sized, and strong winds ensued, driving all the way to Will Rogers airport to wait out the storm in the parking garage. Power was out everywhere, and there was no one at any rental car facility. I contacted my rental car company, and arranged for a pickup of the vehicle, but this had to be at a hotel off I-44, and a slow limp another 10 miles was required, through flash flooding and severe weather. I finally arrived at the motel off I-44 by around midnight and since they had power, stayed the night there. The next day was to wait for a vehicle replacement to be brought down from Tulsa and return to Denver, CO to leave back to FL June 2.
