June 19th took us to the upslope area of the Big Horn mountains in southeast Montana. These mountains are notorious for producing beautiful supercells when upslope conditions occur with decent westerly flow aloft. This day would be no different. Mid afternoon, a cluster of high based storms formed near Sheridan, WY and slowly tracked northeast. One storm on the southeastern side of the cluster tapped into better moisture and instability and eventually became the storm of the day. There wasn’t a tornado threat due to limited moisture, but between wind shear and instability, it developed into a jaw dropping gorgeous storm! As the storm passed into the southeast corner of the state near Baker, it had beautiful structure and also hail the size of golfballs. In the evening, it slowly weakened as it moved into southwest North Dakota. Just a stunning storm on a day when all the ingredients weren’t there! Montana is one of our favorite states to chase in during late spring. Enjoy the pics!!
June 15th Southern Oklahoma Tornadic Supercell
June 15th featured very high dewpoints and instability, as well as good shear and several boundaries for storms to form on. A cluster of storms formed in southwest Oklahoma later in the afternoon and became severe. We followed them towards Lawton as another storm developed on it eastern flank. As we approached Commanche it became tornado warned. Just north of town, it developed a rather large wedge tornado that persisted for over a half hour although it became rain wrapped. If was briefly visible near Loco, OK and caused EF2 damage along the way. After the storm weakened we dropped south on a tail end supercell that was just gorgeous and also tornado warned. Our thoughts and prayers for the town of Perryton, TX that was also hit by an EF3 tornado that day causing much damage and a few fatalities. The down side of storm chasing.
June 11th Raton Mesa, CO Tornado Warned Supercell
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 19th Texas Panhandle Tornado Warned Supercell
May 18th featured a short wave trough moving into the Texas panhandle. It also had a dryline extending along I-27 south and north of Amarillo. Storms started forming mid afternoon along the dryline. Although they couldn’s sustain themselves and eventually died off, they did produce some severe weather. Late afternoon a cluster of storms formed northwest of Amarillo. Due to weaker wind shear, we hoped something would emerge from the cluster due to storm interactions. It certainly did! A supercell emerged west of Chunky, TX and drifted slowly east. It tried to produce a tornado a few times, and was tornado warned. It could never keep a rotation couplet tight enough to produce one. The storm produced baseball sized hail and had very pretty structure. Whenever you get that stack of plates look, you know it is a special storm! Moving very slowly east, it kept it’s intensity for several hours before finally decaying mid evening. A great day and a fun chase! Enjoy the pics!
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!
May 9th Central Kansas Supercells
Surging outflow would be the big deal this day. Storms would form on the cold side of a boundary and have very little tornado threat. However their structure was quite pretty. Elevated supercells would produce hail up to softball size and torrential rain. We chased one storm from near Larned, Kansas east towards Hutchinson. A couple other elevated supercells also formed just to the southwest and became hailers as well. With the elevated nature of the storms, the tornado potential was near zero. Hopefully the huge hail didn’t cause too much damage to the farmlands and ranchers in the area!
May 5th Central Texas Intense Supercell
May 5th brought deep moisture into central Texas, along with moderate instability and decent wind shear. Storms formed west of Hamilton and moved southeast. One storm right turned as it started spinning and moved all the way to the north side of Austin before weakening. It had good structure, monster sized hail and was very electrified. It produced stunning mammatus clouds as well. The rotation buried well back in the core was very strong, and it may have produced a tornado that would have been not visible due to the heavy precipitation. Nonetheless, it was a treat to watch and enjoy!
