May 21st Southwest Iowa Tornado Outbreak

May 21st was a high potential set up in Iowa. A strong dry line, with fantastic shear, high CAPE and deep moisture would create a very dangerous environment in Iowa. By early afternoon storms exploded along the dry line and intensified as they moved east. Initial storms were not tornadic, but as the afternoon progressed, low level shear increased and tornadoes occurred with many storms! Our first tornado intercept was near Red Oak, Iowa as a supercell started spinning hard. The tornado went from a slender elephant trunk to a stovepipe and persisted for several minutes. The second tornado formed southwest of Carbon. It started as a big bowl, then vortices spun up and wrapping rain curtains were rotating violently around it. With motions of 60 mph we had to get out of its way as it approached us within a mile. The next tornado is now probably the most well-known. A strong multivortex tornado formed to our south near Corning and intensified as it moved northeast. It eventually turned into a raging F3 tornado that caused significant loss of property and life in the town of Greenfield. Our heartfelt sympathies go out to those who suffered losses there. Always the downside of significant tornadoes.  Another tornado occurred to our southeast as a cell raced north towards Creston but we lost it due to storm motion and another core with huge hail causing us to have to slow down. Crazy, wild day that most will never forget.

May 20th Akron, Colorado Tornado Warned Supercell

May 20th took us to eastern Colorado for what appeared to be a decent set up on paper. High based storms formed before moisture could work its way west, however they did not last. By later in the afternoon a storm developed rapidly southwest of Akron as a cluster of cumulus deepened. The storm hit the better air and became severe. Structure improved, and soon a lowering developed with RFD dirt wrapping around it. A merry go round ensued. The developing rotation could not tighten enough to produce a tornado, but it was fun watching it try. Lightning became intense so we had to vacate our position and move east and south. Eventually the storm became quite messy and we chose to leave it since we had to be in Iowa the next day on a far better set up (see the next chase account!!!). Enjoy the pics!

 

May 19th Butler, Oklahoma Tornadic Supercell

May 19th had a lot going for it. Good shear, instability and moisture, as well as a dryline in the eastern Texas panhandle set the stage for intense storms to form. By mid afternoon numerous storms formed and it wasn’t long before one updraft became dominant. Structure became quite good, and quickly a very slim tornado formed and disappeared in less than a minute. This just attested to the shear that was present. As the storm moved into Oklahoma, structure became amazing! A big soda can updraft with striations and a wall cloud were visible. As the storm approached Butler, it became tornadic and produced a cone tornado, near Custer City followed by w wedge north of Hydro. We got in intense RFD and had trees coming down around us, so we had to get out and move them ourselves so we could continue the chase. As we later past ElReno, we stopped at an exit and filmed the storm coming at us, complete with rapid rising and twisting scud, which soon a debris cloud appeared. We were trying to get through OKC and head north for the night and didn’t want to chase in the city as a substantial tornado touch down south of ElReno. Chasing at night is a challenge, but around a larger city, it is dangerous. We drove north to spend the night in Salina and get ready for the next day which would be a chase day. Enjoy the pics!

May 15th Ponca City, Oklahoma Supercell

May 15th featured a boundary across far southern Kansas into northern Oklahoma. Strong convergence, decent moisture and good shear would set the stage for supercells to form along it. By mid afternoon, storms did just that. One main supercell developed and right turned into northern Oklahoma. Structure was very nice and at one point it even produced a funnel halfway to the ground. The supercell was a prolific hail producer with stones falling as large as softballs. As it moved east, it eventually out ran the instability and weakened near dark. One of the prettier supercell of this year so far, and even though it didn’t produce a tornado, the guests loved it! Enjoy the pics!

May 8th Springfield, Tennessee Tornadic Supercell

May 8th had a lot going for it. Strong instability, good shear, high CAPE and several boundaries played into the end result. We caught several tornado warned supercell, including one near Springfield, TN that produced a cone tornado. Between slow, curving, winding roads, low speed limits and slow traffic, it made it difficult to get in front of storms. The Springfield supercell spun like crazy and produced a cone, causing damage. It took us what seemed like forever to get in front of it. As we broke through the core, we could see the cone tornado behind us in the distance. It had been on the ground over 10 minutes. As we got into a better position to see it (due to hills and trees!), it dissipated. We then blasted south to catch a supercell near Columbia, TN that showed signs of strong rotation and was tornado warned. As we approached Nashville, insane traffic slowed us down by 30 minutes. And of course the supercell produced a violent wedge tornado that became rain wrapped by the time we could get to it due to traffic. Frustrating day, but we DID see a tornado! Tennessee and Kentucky are extremely difficult to chase in!!!! Enjoy what pics we could get!

May 4th Davis Mountains Tornadic Supercell

Even though May 4th was the last day of the tour, we could not pass up the chance to chase the set up this day. Upslope flow, good moisture and instability, along with good shear provided the needed ingredients for supercells and potential tornadoes this day. We knew storms would start out high based, but their bases would lower as they moved east off the mountains into the lower lands where better moisture resided. That is exactly what happened. A cluster of storms formed, of which the tail end cell took over and became dominant. A quick spinup occurred as low level rotation cranked up under the updraft We had to vacate our position due to huge hail falling and drove east of Ft Stockton to a south bound road that would be give a view. The only issue is there just aren’t many roads in this part of Texas.  As we drove south, rotation increased as the supercell dropped a rather large cone. It became rain wrapped after a few minutes so we continued southward to where the road put us directly in front of the supercell. Soon cgs started raining down from the updraft and rotation became focused. Several tornadoes formed and rotated around the wall cloud. It was quite the sight!!! After becoming strongly HP, we blew it off since we had a 600 mile drive back to Oklahoma City that night. 3 am arrival, but everyone was stoked due to the excellent day we had! Enjoy the pics!

 

May 3rd Southwest Texas Tornadic Supercells

May 3rd kept us in southwest Texas near San Angelo and vicinity. Strong instability, good moisture, high CAPE ad decent shear would set the stage for several supercells. A tornado occurred near Silver, Texas early on as we tried to get over to the supercell. Due to one lane roads and closed roads, we could not make it in time, so we dropped south towards San Angelo and played another supercell that had formed and anchored on a boundary east of Town. It had a very pronounced clears slot with rapid rotation in the mesocyclone, and dropped a quick brief dusty tornado.  As we pushed east near Eola and watched couple brief landspout tornadoes. RFD was wrapping hard to our north and we decided to explore it. A big bowl formed with tons of blowing dirt, and eventually a brief tornado occurred. Soon numerous storms exploded and things became messy and outflow dominant. At this time, we decided to get away from the mess and call it a day. Fun day, a bit frustrating due to closed roads, etc, but another day with supercells and tornadoes is always a good day! Enjoy the pics!

 

April 30th Red Oak, Iowa Tornado Warned Supercell

April 30th provided a fast moving, but strong upper level system across the central states. Moisture was sparse, but racing north of southerly low let jet winds. We knew it would be close to get enough good moisture to allow cloud bases to be low enough to produce tornadoes in Iowa. By mid afternoon clusters of storms for in southeast Nebraska. One such storm intensified as it moved into southwest Iowa. It became severe as it moved further east and eventually became tornado warned. On radar it looked like a classic tornadic supercell, but in real life, it’s base was just a tad too high to produce tornadoes. It was a prolific hailer and had nice structure. At one point it had a very large wall cloud that had the look. However, it could never maintain tightened rotation, only broad slow motion. A pretty storm, but just couldn’t produce any tornadoes. A fun day nonetheless!

 

April 26th Iowa Violent Tornado Outbreak

April 26th had the appearance of a major tornado outbreak. It certainly lived up to the hype! We had spent the night in Salina, Kansas and targeted Nebraska City, NE to Creston, Iowa for tornadic supercells. Strong wind shear, with dew points in the lower 60s and surface based instability of 2500 CAPE would set the stage for the event. We arrived in the Nebraska City area mid afternoon, as a supercell produced a couple of tornadoes between Lincoln and Omaha, Nebraska. Due to storm motion and speed, we could not catch up to it, so we decided to stay put. An hour later storms erupted along a confluence line near the Missouri river and quickly gained rotation. Near Council Bluffs we decided to go east and get in front of a tornado warned storm. When we saw it, it was ready to produce a tornado. As it approached a cone shaped tornado formed, turning into an 800 yard wide EF3 wedge tornado as it crossed the road within a half mile of us. It completely destroyed 2 farmsteads along highway 92 and as we approached them, nobody was there to help the residents. We immediately stopped and went into search and rescue mode. We found a family trapped in their storm shelter as their home collapsed on them. After removing a lot of debris as a few other chasers stopped to help, we were able to get them freed. Shook up, but healthy, attention turned to the other farm. An elderly woman and her dog were buried in debris as her house was demolished except for the walls. They also were able to be rescued. Soon paramedics and the local fire department arrived as we directed them to the residents and told them about propane tank leaks. At that point, it was time for us to leave and let the authorities do their jobs they did so well!

By the time we were able to depart the scene, it was too late to keep chasing as the tornadic supercell was 15 miles north moving away. It went on and produced more strong tornadoes near Minden and Harlen as we turned south to make the journey back to Oklahoma City. I do NOT regret missing the other tornadoes to stop and render help to those in need. Given the opportunity to do it again, there would be no hesitation!!! People are far more important than weather. Thanks to all who stopped that day to help families in desperate need of assistance.

April 23rd Sweetwater, Texas High Based Supercell

April 23rd promised some decent severe weather opportunities. However due to lack of good moisture, storms were high based. We intercepted one storm northwest of Sweetwater and stayed with it all the way south of Abilene where it gusted out. Structure was pretty and the hail up to golfball sized. It was also a pretty decent lightning producer. As it reached maturity and started weakening an haboob developed spewing red dirt all over. Winds were gusting over 70mph. All in all a decent day for the ingredients available to produce intense storms. Enjoy the pics!
