May 11th had a lot going for it. Good upslope flow into the Raton Mesa, decent moisture and instability and great wind shear would set the stage for supercells this day. Storms formed early afternoon and became tornado warned. We blasted west from the Oklahoma panhandle into the mesa in time to watch a supercell get very interesting. Couldn’t confirm any tornadic activity, but it certainly looked like it had potential. This storm also produced baseball sized hail and high winds. It was a treat to photograph and watch spin across the mesa into the Oklahoma/Texas panhandle. Fun day for all the guests who witnessed this beauty! Enjoy the pics!
May 23rd West Texas Supercells
May 23rd brought great wind shear, but marginal moisture. Several supercells formed along the TX/NM border east of Clovis, NM. One high based storm took on the classic spaceship appearance and was visibly rotating. A little nubby funnel formed and even touched down briefly (confirmed by the NWS). It was quite pretty and also produced a lot of lightning strikes. As it moved east it became less intense so we blasted to a boundary southeast of Plainview, TX. This storm tried to produce, but low level shear was just too weak. It had great structure as well and spun hard for a couple hours before weakening. A great day with the environment we had! Enjoy the pics!
May 22nd Texas Panhandle Supercells
May 22nd brought decent moisture, good instability, a Texas dryline and moderate shear. By early afternoon, cumulus towers were forming along the dryline from Amarillo south to Lubbock. A bulge in the dryline was evident around Tulia and that’s where we intercepted our first supercell. It only took about an hour for the storm to really get organized and quickly a small funnel cloud formed. It persisted for a couple minutes. A blocky wall cloud formed and started rotating. However, it was quickly undercut as a new cell formed to the southwest. As the storm weakened another supercell formed northwest of Lubbock. We headed south for that one as a ragged wall cloud formed. As the storm moved east, it encountered higher temperatures and lower dewpoints which caused the storm to become high based, thus lessoning the chance of it producing a tornado. It did produce a high based funnel near Crosbyton and also produced hail golfball sized. Soon after, it weakened coming off the caprock and the chase was ended.
May 13th Pleasantville, Iowa Tornadoes
May 13th showed significant moisture and instability along a warm front and outflow boundary from previous days’ convection. The boundaries met and formed a triple point southwest of Des Moines, Iowa. Storms fired very early by 1pm and became tornado warned. Nothing significant formed but we stayed with them. Several false reports of multivortex tornadoes occurred, which has been the case all spring. The old philosophy of if you aren’t sure it’s a tornado, it is not one should be taken by many storm chasers! Numerous tornado warnings were issued, and the monster supercell spun like crazy. It eventually weakened as it moved east off the boundary. Another supercell formed southwest of Pleasantville and produce at least 3 tornadoes that we witnessed. A multivortex, an elephant trunk and then another multivortex that was less than a quarter mile from us! The motion was incredible right over the vans as this tornadic storm drifted northeast and produced. An overall exciting day that the guests loved! Enjoy the pics!!!!
May 12th Nebraska Tornadoes
A great set up on May 12th took us to an arching boundary across central and eastern Nebraska. Early day storms produced weak tornadoes over north central Nebraska, but since our target was further east, we decided to wait it out for what we hoped were more violent storms. The wait paid off and numerous storms formed, almost all tornado warned, from northwest of York to north of Lincoln. One particular storm became violently tornado near Scribner, NE as we watched it produced a large partially rain wrapped wedge, then another elephant trunk shaped tornado in front of it. The wedge was rated EF-2 and the elephant trunk EF-1 as they hit a few structures, but fortunately nobody was killed. It was a murky day with a lot of low level moisture in place so apologies for the murky looking photos! Enjoy!
May 11th Central Oklahoma Tornado Warned Supercells
Great potential on May 11th!! Good moisture and instability would occur, as well as lift along a dryline, would result in several tornado warned supercells and one that produced a couple of night time tornadoes near Noble, OK. We chased south of the OKC area early as a supercell formed. It eventually died off as it ingested dry air. However, north of that several storms went up and spun, becoming tornado warned. One storm took us towards Lindsay, OK and attempted to drop a tornado. The funnel came halfway down and receded. Structure was very pretty as the supercells became very well organized. In a weird ending, one of the first storms we chased dropped the tornadoes. This storm was in the middle of a line of supercells, which typically is unusual. Almost always chase the tail end storm that has no competition for air, but this was not the case today! Enjoy the pics!
May 10th Akron, CO Tornado and Supercell
May 10th had great potential in eastern Colorado. Upslope flow, and approaching short wave, good moisture and moderate instability would set the stage for intense storm formation by early afternoon. Initial storms would cluster and produce copious amounts of hail around the Denver metro area and just east. A boundary draped along I-76 eastward towards Wray would be the focus for a few supercells that would produce a couple tornadoes. We were heading towards Akron when we encountered a HUGE line of chasers stopped at construction red lights. This delayed us almost 30 minutes! We ended up watching a tornado from the construction back up and had no way to get east due to flooded and extremely muddied dirt roads. A frustrating day, but at least we managed to catch a tornado!
April 22nd Doole, Texas Potentially Tornadic Supercell
An interesting set up with northwest flow aloft on April 22nd. A weak low along with a sharpening dryline and warm front, set up a triple point northwest of San Angelo, Texas. Moisture would be the issue as dewpoints were in the 50s. Shear was good and convergence at the triple point would fire off a storm that became a long lived supercell. As the storm turned along the boundary, it started spinning strongly. After an interaction with another weak cell which it destroyed, it developed intense rotation, and on radar a classic scorpion tail hook echo formed with a good velocity couplet. RFD dirt was seen wrapping around the southern periphery of the storm and soon a large dirt bowl formed and persisted for about 5 minutes. Tornado? Possibly. But the storm also had hail the size of softballs. It soon moved east into less unstable air with lower dewpoints and it slowly decayed over the next couple of hours. A GREAT way to start the 2023 official tour season with Tour #1, the Close Encounters tour, witnessing this supercell. Enjoy the pics!!!
April 4th Pleasantville, IA Tornadic Supercell
April 4th was a complicated day. A powerful upper level low would pivot out onto the plains late in the period. Low level moisture was fairly shallow for a big event, with pockets of dry air mixing out the better moisture. It seemed like two areas would be the best targets: 1) southwest Iowa as the forcing came out, however moisture was forecast to mix (and did!), 2) southeast Iowa and western Illinois in the free warm sector. We sat in Ottumwa for a couple hours waiting for one target to become clear. It never really did. A cluster of storms formed in eastern Missouri and consolidated into a few supercells as they moved into western IL. We started to head that way to chase, but it would have been a long way back to Kansas City that night as several guests had to be back in Denver by late afternoon the next day. Shortly after we headed out to go to IL, the Iowa play started forming. A line of storms, now severe, formed along the dryline west of Osceola and moved east. The tail end storm really started getting it’s act together so we quickly turned around and headed toward Pella (where we saw a tornado 2 years ago!). As we approached Pella, a tornado warning came out with a confirmed tornado towards Pleasantville, which was another 15 miles west. We did all we could to get there, but were only able to get a glimpse of the pretty tornado before it dissipated. We stayed with the supercell as it approached the warm front and became tornado warned again. A brief spin up happened south of Malcom. The storm continued its path across the warm front, weakening in the colder air. Here’s a few pics of what we saw with the supercell, distant tornado and the second spin up. Enjoy!!!!
July 16th Central Nebraska Tornado Warned Supercell
July 16th featured very high dew points in the mid 70s and CAPE values over 3000 j/kg. Shear was modest, so we weren’t certain we would get supercells. An early day supercell over eastern Nebraska laid out an outflow boundary over central Nebraska from Valentine southeast towards Grand Island. Storms formed along this boundary and moved east into the cool stable air and died. Later in the afternoon a cluster of storms formed on the boundary and the tail end storm anchored. It immediately started spinning and became a formidable supercell! As the storm right turned on the boundary and moved towards Burwell, it was rotating strongly and was extremely electrified! I thought it had a decent chance to produce a tornado, but it did not. A couple of weak funnels did form. As the storm continued southeast, it became tornado warned with strong rotation continuing. Another supercell formed west of this and rotated down towards I-80 near Gibbon and also became tornado warned. The structure was incredible with one of the best shelf clouds I’ve seen in years! As the storms pushed south of I-80, they gusted out and became a wind machine. A great day with far better results than we were expecting! Enjoy the pics!
