The final tour day of our 2020 season brought us into southeast Wyoming to play in the upslope flow into the Laramie Range. Several storms formed in this region and tracked southeast towards Cheyenne and points east. Decent moisture and instability, coupled with moderate shear, would help storms become organized and develop into some pretty structured supercells. Our first storm, north of Chugwater, had nice structure and produced a lot of hail. It spun hard a couple times and at one time we thought it had some tornado potential. It get really messy so we decided to target a new cell southeast of Cheyenne near Carpenter. This storm was a treat to watch! We found an old abandoned car that became the centerpiece of our photos/video as the cell slowly dropped towards us. The storm’s structure was that of the classic “stack of plates” and was fun just to watch as it drifted towards us. Both of the storms we chased this day had great structure and were very photogenic. Enjoy the pics!
July 19th was a spectacular day! Good moisture, high instability, good wind shear and a boundary along the Wyoming/Montana border would set the stage for intense supercell development. One such storm formed northwest of Devil’s Tower and drifted southeast. As it crossed Devil’s Tower we had quite the lightning show! I managed to capture a bolt hitting the top of the tower! As the storm moved southeast near Sundance it became extremely electrified producing a CG every 3-4 seconds! At one point, it had an appearance like it was ready to produce a tornado. We lost visibility in the hills and could not confirm one way or another if it did. Later, a second supercell tracked southeast from near Buffalo, WY down to Lusk, WY. This storm constantly spun hard, had pretty structure and was also tornado warned numerous times! It’s structure was top notch and had various rotating wall clouds throughout it’s life. But, as continued to be the theme for 2020, storms had great structure but just couldn’t produce significant tornadoes. Overall it was my favorite day in July for chasing, and one we captured some incredible photos! Enjoy!
July 14th kept us in Colorado to chase off the Palmer Divide into southeast Colorado. A sagging cold front we push moisture westward into the Palmer Divide, causing storms to develop by mid afternoon. Those storms produced copious amounts of hail, but became undercut by outlfow and died. The boundary pushed south as more storms formed along it east of Pueblo. Near the town of Sugar City, one storm formed and spun hard. It quickly became tornado warned and stayed that way for a few hours. A couple of times, it had the look like it wanted to drop a tornado, but it never did. As it merged with numerous storms west of Lamar, the storm interaction with others caused it to produce a quick 1 minute spin up. The structure with this supercell was quite nice. It was also quite electrified! Eventually this cluster of storms pushed into western Kansas and weakened as we followed it east to Garden City. Great day! Beautiful storm and it certainly tried to get very interesting! Please click on a pic for a larger image. Enjoy!
July 13th was the second day of our Tour 9, Great North Tornado Hunt tour, and it took us east of Denver towards the Kansas border. Decent shear, limited moisture and CAPE, and an approaching dryline, would set the stage for high based storms to form. As the storms moved into Kansas, they intensified and the bases came down. We had a couple very pretty rotating storms in far western Kansas that were quite electrified. The final storm of the day was a very nicely structured LP supercell near Leoti, that spewed out numerous lightning strikes and intercloud discharges. I thought for a minute that it had some tornado potential, however the base lifted, the wall cloud dissipated and it eventually died as well. A fun day, great storms and super lightning.

July 6th was an inbetween day for our tours. However, as we often do, if there is a decent set up, we’ll run one of our on call tours. That’s exactly what we did the 6th and 7th! On July 6th we started in Denver and blasted to southeast Montana where storms were forecast to form along a boundary with good instability and shear. We’ve seen numerous tornadoes in this region over the years and some outstanding supercells! Today would be no different! We made it south of Broadus, MT and turned east on a dirt road near Biddle. We had a great view of the developing supercell. As we continued east, the forward flank core caught up with us so Caryn had to push it a bit to get out of the heavy rain so we wouldn’t get stuck. Low and behold as we were blasting east on muddy roads, trying to get south of Alzada to head south towards Hulett, WY, our wonderful storm tornadoed. Couldn’t see it from our location, thanks to horrid road network. However, if you were north of Hulett, you had a decent, albeit distant view. We stayed with the storm as it crossed the Black Hills near MT Rushmore and onto the nearly plains. It became a stunningly beautiful supercell as it tracked towards the Badlands. Gorgeous!
On the 7th we played southeast Montana again. However moisture quality was much poorer than the day before. Storms formed along a boundary and became a squall line as they moved east. They were still pretty and offered some very photogenic moments! We stayed in front of them back to Rapid City, SD where we spent the night before returning to Denver the next day.

July 3rd brought us back to Colorado for the final day of the Photo Tour. Nature decided to give us some pre4th fireworks! A boundary set up north/south of a line from Ft Morgan to east of Limon. Intense storms formed along it and with a wind shift in place, two landspout tornadoes formed that we were able to witness. They lasted several minutes each before dissipating. Storms were quite sever with hail tennisball sized and lots of lightning as well. We intercepted the first cells on highway 71 south of Brush and followed the southward building line from there. Good shear, moderate CAPE, but limited low level moisture fueled the severe storms till eventually they gusted out and weakened. Fun final day of chasing for the tour before returning to Denver later in the evening. Please click on a pic for a larger image. Enjoy!
