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 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 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!

May 4th Crowell, Texas Tornado Warned Supercell

May 4th was a strange day. A decent threat of severe storms and low end tornado potential existed. High based storms formed off the caprock by mid afternoon and moved east. Bases never lowered. Another couple of storms, eventually supercells, formed along a boundary a bit further east southwest of Crowell, TX. Within a few minutes a lowering formed and exhibited some rotation. As the storm moved east, a line of storms formed in front of it, thus limiting the quality of inflow air into the supercell. It caused it to slowly weaken over time. The storm produced baseball sized hail, high winds and was tornado warned for a couple of hours. It showed a fantastic hook echo on radar, but it just couldn’t sustain with cold inflow from storms ahead of it.

May 2nd West Texas Supercell

May 2nd wasn’t expected to be a big severe weather day. Limited moisture would cause storms to be higher based with little tornado threat. That’s exactly what happened. Mid afternoon, storms formed along the New Mexico border ad became severe. They produced hail golfball size and high winds. Lightning was pretty after sunset as well. A fun day on a day we didn’t expect anything substantial to happen.

April 25th Sweetwater, Texas Stunning Supercell!!

April 25th featured a short wave trough approaching Texas. This lead to a surface trough in eastern New Mexico that helped bring moisture northward from the gulf of Mexico. Southeasterly surface winds raced northwest towards a dryline in west Texas where a weak low had developed. Models were fairly consistent developing storms, some supercells, near the Snyder/Sweetwater area and they nailed it. We approached Sweetwater later in the afternoon as cumulus towers were seen. A high based severe thunderstorm produced a couple shear funnels due to strong motion at cloud base. This storm became a prolific hailer as it moved towards town and eventually to the southeast.

South of town, the structure was magnificent! A sculpted updraft with striations showed just how well organized this supercell was. As darkness fell, the storm maintained its intensity as it moved southeast. Lightning illuminated the structure in the dark and made for quite the scene. Finally, about 10pm we let it go as it weakened and we drove towards Abilene where we spent the night. We came across copious amounts of hail, some close to tennisball sized.  A fun day and it’s always amazing to see nature’s artistic side in a gorgeous sculpted supercell! Enjoy the pics!
