A major change in the weather pattern started around July 5th. An expanding ridge was developing in the west, with one lone weak short wave dropping down the eastern side of it into the southern plains. This is very late in the season to be chasing that far south, but you chase what nature gives you! We headed south on the first day of the tour and were greeted with several high based storms, some rotating, northwest of Lubbock. A couple mid level funnels occurred, as did hail baseball sized, however, due to high bases, there was virtually no tornado threat. Tons of blowing dust happened as thunderstorm outflows became quite strong, and many gustnados formed. Pretty cool sight, but this would be the last day of this tour that would chase the plains states. Summer heat and ridging came early this year.
June 25th Whitman, Nebraska Incredible Supercell and Strong Tornado
June 25th had a lot going for it. Dewpoints in the 70s, an old outflow boundary, high CAPE and convergence would get storms exploding in the afternoon hours. We targeted a pair of severe storms west of O’Neill, NE and watched them intensify and move south. However the western most storm quickly died when it moved over the boundary and the second one also met the same fate. Meanwhile towards Norfolk a supercell became tornado warned and produced a brief tornado. I always watch trends in surface observations and satellite and noticed the boundary sharpening up and angling towards the northwest to the west of us. Moisture was rapidly increasing with dewpoints in Thedford, NE rising from the low 60s into the low 70s with strong easterly winds. Soon, a storm formed along the boundary northwest of Mullin and anchored for awhile. It steadily intensified as we blasted west. By the time we got to Thedford, the storm was strongly severe and we could see an impressive mammatus field under the anvil. As we continued westward to get a better view, the storm formed a strong couplet and a hook. Structure was starting to become visible as we approached Mullin. We continued west and soon were greeted with a magnificent sculpted supercell and a rapidly growing tornado! The tornado grew to an impressive cone, then wedge as it moved south towards the small town of Whitman. We stopped about 3 miles from it as it was getting ready to cross the road and continue southward where we had no south roads! Frustrating! The sight of both the supercell with large tornado under was the best I’d seen in 2024!! Just an amazing scene! We had to back track to Mullen and drop south so we could catch up to the supercell again. We would not see the updraft again in the daylight. As it approached North Platte, it weakened and eventually died. An absolute phenomenal day! Unfortunately the tornado hit a couple of houses near Whitman and caused significant damage and 1 injury. I shudder to think what could have happened if it hit the town directly!

June 16th McCook, Nebraska Gorgeous Supercell
June 16th brought us to southwest Nebraska near McCook. A triple point focused potential storm development in the area with extreme heat (temps over 100) along the dryline with dewpoints near 70 along the warm front. Many updrafts tried to form in the area near the triple point, with one updraft succeeding in sustaining itself at the triple point. The storm sat and spun for several hours. The structure was quite pretty and periodically the storm produced copious amounts of lightning. Although never a real threat to produce tornadoes due to higher cloud bases, a couple of wall clouds formed and one bowl spun for several minutes. The storm persisted towards sunset then slowly weakened as it drifted slowly northward. An exceptional day based on how model portrayed the set up. Enjoy the pics!
May 31st Eastern Colorado Supercell
May 31st featured a short wave trough moving across Colorado, with limited moisture, but strong shear. Most models developed storms off the Palmer Divide, intensifying as they moved east/southeast. That is exactly what happened. A storm started spinning and became tornado warned west of Cedar Point, but never showed strong enough rotation to produce a tornado. Another storm formed to the south of it and ended up being the storm of the day. As it steadily intensified, a severe thunderstorm warning was issued for it. As it approached Limon a DESTRUCTIVE STORM warning was issued for hail baseball sized. We encountered hail about golfball size as we had to punch the core and get ahead of it south of Hugo. About 10 miles south of town, structure became quite nice and a lowering formed with slow rotation. I thought for a bit that it might produce a tornado, but to no avail. It never could balance its updraft and downdraft well. With the sun getting low in the sky and having to be back in Denver soon, we waived goodbye one last time and headed home. A fun day and close to Denver made it an even better treat! Enjoy the pics!
May 30th West Texas Supercells
May 30th brought an interesting chase. A sharp dryline and an outflow boundary would intersect over west Texas and provide the focal point for severe weather. Storms formed at the triple point but could not sustain themselves for very long as they moved out into more stable air. We ended up dropping south from Morton, Texas to Denver City, Texas as one storm formed, hooked hard and tried to produce. In the end the only storm that produced was near Midland, Texas as it dropped two substantial tornadoes. Our storms looked good, but due to a bit higher cloud bases, they could not get a circulation down to the ground. Overall a fun day but a bit frustrating as we were so close but not close enough with our storms.
May 29th Clovis New Mexico Tornadic Supercell
May 29th was a marginal day at best. Southeast Colorado looked like the place to be. However, with moisture pooling along a boundary in east central New Mexico, I had a hunch that would produce decent supercells late in the day and evening. The Colorado target got interesting and produced a couple tornado warned storms ( See the previous chase account for the Prime Time Minitour!!!), but I chose to wait and see what would happen in New Mexico. I was not disappointed!!!! By early evening as a short wave trough approached, storms developed northwest of Clovis. It didn’t take long to see they were anchored and would start spinning quickly. As we approached the northeast side of Clovis, a tornado warning was issued. Numerous images from various locals and also my defunked video camera showed what appeared to be a cone tornado northwest of town. The NWS in ABQ is currently validating the tornado based on images, video and local chasers in the area. We nearly had the storm to ourselves, which is quite rare in this day and age!!!! We dropped through Clovis and ended up north of Portales, NM and sat and watched the storm spin like crazy. It was constantly tornado warned. The structure was absolutely top notch, even in the dark and hook after hook formed on this anchored supercell! Finally, by late evening, things started winding down, so we drove to Amarillo to our hotel for the night. One of the BEST structured supercells of 2024, even in the dark! Please enjoy the pics and NO they are not photoshopped!!!!
May 29th Southeast Colorado Tornado Warned Supercells
May 29th brought the last tour day of the Prime Time Mini-tour and Mother Nature brought some nice storms for the ride back to Denver. Started the day in Lubbock, TX with a plan to chase around the Springfield, CO area. Moisture started to mix out in that area, but a nice cumulus field started to build just west of Lamar as a weak La Junta low was forming. We headed for that area and watched from just south of Highway 50 as cells developed between Caddoa and Lubers. As the cells consolidated, lightning became more frequent and we got some nice lightning photos. The southernmost cell then became severe warned and we headed towards the east side of Wiley to stay in front of the strengthening southern storm. After a short time, we had to reposition to the east again along county road 196 and then south to Highway 50. During this time, the cell just to the north of our storm became tornado warned (radar indicated). Unable to get closer to the northern cell, we were able to watch that supercell and the southern LP supercell from our position. As both supercells began turning hard right over and just to the east of Lamar, we took dirt roads to get to a great vantage point looking over open land and observing both cells. The northern supercell was once again was radar indicated tornado warned, but no tornado was observed nor reported. The storms were nearly stationary at this point, moving southeast very slowly which allowed us lots of time to watch and admire. As darkness set in, we decided to start our 4 hour drive back to Denver. Working our way around the south side of the storm, we were treated to an incredible view of the structure of the southern LP cell, causing us to stop and take more pictures. A great day was had by all, super way to end the 4 day tour!
May 28th Morton, Texas Supercell with HUGE hail
May 28th set up had a dryline in west Texas, with strong southeast winds bringing modest moisture westward. Moderate CAPE developed as well and storms formed mid afternoon along the dryline. Storms pulsed quite a bit, and due to straight hodographs, storms split and many mergers occurred. Eventually a supercell developed, anchored near Morton. Structure became better, but due to modest moisture, the cloud base was too high to produce tornadoes. As it moved east it encountered a boundary and spun nicely. After several cycles, it produced 5 inch diameter hail west of Lubbock! We blew it off as it weakened and played further south with a supercell that had softball sized hail. The tornado threat this day was quite low due to high bases, but with strong shear in place and low freezing levels, storms were prolific hail producers.
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!
