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!
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.
May 29th Central Nebraska Tornado Warned Supercell
May 29th was the classic “day before the big day” type set up. Moisture and instability were rapidly increasing along a lifting warm front in Nebraska, and shear was quite strong. Models showed late afternoon and early evening supercells forming north of Broken Bow and that is exactly what occurred. It took awhile from the main supercell to root along the boundary and get organized, but once it did, it became a formidable storm! Eventually it became tornado warned as it moved to the northeast and stayed warned for a few hours. Due to storm motion and poor roads, it became virtually impossible to stay with it. Near O’Neill we had to let it go and head to Sioux Falls, SD for the night. The storm had good structure, and it had a well defined rotating wall cloud. It just couldn’t tighten enough to get a tornado to form. Enjoy the pics!
May 24th San Angelo, Texas Supercell
We weren’t expecting big things this day. An advancing cold front was pushing south across the area near San Angelo and the fear was it would undercut storms that would develop. As we arrived, one storm rode the boundary for a couple hours before being undercut and became for formidable supercell. It dropped hail the size of softballs and had some really pretty structure. However, as feared, the cold front continued to push south and undercut the storm. From then on it was a battle to stay ahead of anything that wouldn’t be undercut as the front continued its steady push southward. A quick end to the day, but still a fun day w
ith a great supercell!
