June 25th Devil’s Tower, Wyoming Tornadic Supercell

June 25th had a lot going for it. Strong shear, good moisture and increasing instability were present, as well as a nice boundary along the Black Hills Convergence Zone (BHCZ). Initially storms formed in the drier, well mixed air off the Big Horn mountains in north central Wyoming. These cells moved east with one storm in particular taking over and becoming a pretty high based supercell. We stayed on the back side of it east of Wright and watched it race off into the southern Black Hills.

I had a hunch that more storms would form along the boundary, and due to good moisture, these cells would not be so high based. A few storms formed south of Broadus, Montana and moved southeast along the boundary. The tail end cell, as usual, took over and became a very formidable supercell. As this storm approached the area just north of Hulett, twin EF1 tornadoes formed (Per NWS damage survey). We could briefly get a visual of one of them. Structure was superb, and the lightning was very intense. As the storm approached us, we had to blast south to Hulett to get out of it’s way. It raced eastward and we had no way of staying up with it. Other storms also formed and became quite electrified. We stayed with this cluster through dusk when they weakened. Two pretty, but very different supercells from each other and two tornadoes. Indeed, a great chase day to kick off the SLT Photo Tour #3! Enjoy the pics!

June 17th West Texas Tornado Warned Supercell

Sometimes, you just don’t care if a storm produces a tornado. It can be that pretty. Dryline supercell thunderstorms can be quite pretty, although they are often higher based. This day would give us just that. We had a high based supercell that formed along the Texas/New Mexico border and drifted slowly southeast towards Muleshoe, Texas. It spun like crazy. There was plenty of shear and instability this day and with the active dryline closeby we were hoping for a pretty storm. Active for several hours, this supercell produced incredible lightning, some of the best of 2019 to date and had nice structure.

Other storms would form later in the day and especially during the early evening as the cap was breached. Many of these storms were very electrified and intense, often being warned for large hail and damaging winds. A couple storms would become tornado warned, however no tornadoes occurred this day in our area. All in all, a fun day with a great storm and superb lightning!

June 8th Northwest Kansas Tornadoes

June 8th continued our streak of tornadoes for each tour! Two twisters formed north of Goodland along a boundary. Decent instability and moisture, as well as a wind shift boundary, would provide all that was needed to get supercells to form. One tornado formed late afternoon, and soon a second would also form as the first was dissipating. They both were on the ground for over 5 minutes as they slowly drifted eastward along the boundary. They were quite photogenic as well!

Later in the evening, a supercell came off the higher terrain of eastern Colorado and was very photogenic. Near Flagler, CO the storm had beautiful structure and quite nice colors too! Even a funnel formed briefly under the inflow side of the updraft! After a couple hours the storm eventually weakened as it moved into more stable air, leaving behind an amazing mammatus display! A great way to start the tour!

June 4th Artesia, New Mexico Tornado

What a surprise day this was! Upslope flow and terrain circulations can do magical things in the high plains and this day would be one of the best! Poor wind shear, marginal moisture, but decent CAPE would provide at least some threat for severe storms. We were in Roswell, New Mexico the night before and decided to stay around for the action on June 4th. We dropped to west of Artesia as one LP supercell formed and produced copious amounts of hail. As it moved off the higher terrain it weakened and died. However, a group of storms formed and slowly intensified as they remained anchored on the foothills west of town.

As we positional ourselves on the eastern most storm, something strange happened. The storm started to get well organized and show signs of rotation. Soon a small wall cloud formed. From this wall cloud, a funnel dropped down and planted firmly on the ground for a few minutes. However due to the higher cloud bases and lack of appreciable moisture the funnel never fully condensed to the ground, but a debris cloud rose up from the ground to show it was connected. It persisted for several minutes before weakening and dissipating. We then came back into town and dropped south to Carlsbad to watch the cell drift towards town. It maintained it’s supercell characteristics for a bit before gusting out and dying. A great day and a nice surprise tornado kept our streak of consecutive tours alive with all seeing at least one tornado!

May 27th Northeast Colorado/Southwest Nebraska Tornadic Supercells

This day had a lot going for it. Great shear, good moisture and instability, and a dryline would help set the stage for intense supercells. Our first storm of the day formed near Ft Morgan and tracked northeast along I-76. It became a rather large and occasionally disorganized supercell. However as it approached Sterling, it wrapped up hard and produced a brief, small tornado. Further to the east, a second, well organized and photogenic supercell formed. It produced a few brief tornadoes, however the structure of this storm would be one of the prettiest for 2019! As it came towards Imperial, a beautiful sculpted storm was present. At one point west of town, not only did the storm have a stunning appearance, but a partially rain wrapped tornado became visible. The cone shaped twister was on the ground for a few minutes before wrapping in rain again as we lost visibility of it. An amazing day with gorgeous storms and a few tornadoes! Enjoy the photos below!

May 26th Southeast Colorado Tornadic Supercell

May 26th ended up being an exciting Colorado storm day! We captured a tornadic supercell just north of Lamar that had a brief pretty white elephant trunk shaped tornado. The day started out really messy as numerous elevated thunderstorms formed over eastern Colorado. An existing boundary that was visible underneath the elevated storms would set the stage for late day supercells, one of which was long lived and quite nice. By mid afternoon we were watching storms west of Lamar. They were in drier air with high cloud bases and could never really get intense.

Further east towards Lamar one storm rapidly developed along the boundary and tracked northeast. Moisture, instability and wind shear was much better in this location! It quickly dropped a funnel that persisted for nearly 10 minutes, touching down a couple times but causing no damage in the rural areas. It moved northeast and weakened as a second storm approached from the southwest and became tornado warned. It tried hard several times to produce but in the end it never did. We followed it northeast to the Kansas border before dropping further south and east into Kansas for late evening lightning. An exciting day in Colorado and western Kansas! Enjoy the pics below.

May 22nd Northeast Oklahoma Tornadoes

May 22nd featured incredible surface moisture and very high CAPE values as well. I was a bit concerned with upper level winds, but down low it appeared sufficient for tornadic supercells, especially with vertical stretching due to strong instability. We started the day heading towards northeast Oklahoma in the Tulsa vicinity. By mid afternoon storms exploded near I-40 well southwest of the city, so we headed that way. We arrived west of Okmulgee as a tornadic supercell approached. It produced a nice multivortex tornado about 1 mile to our west, followed by a cone just north of us. As the storm moved northeast it weakened as a second tornadic supercell approached town. This storm would produce at least 2 more tornadoes that we could confirm and possibly a 3rd brief tornado northeast of the city. Structure was nice and for last May storm motion wasn’t extremely fast. All in all a fun day. Later in the evening a couple intense tornadoes occurred in Missouri that fortunately did not cause any loss of life. Enjoy the pics below!

May 20th Texas/Oklahoma High Risk Day

My 20th looked downright scary on all models. SPC issued a HIGH RISK for long tracked violent tornadoes and had a greater than 95% probably of numerous/violent tornadoes on their tornado watch box they issued. Schools closed, Air Force bases evacuated aircraft, lots of safety precautions were made. It ended up being a major, major bust. Very few tornadoes occurred and there were no violent tornadoes. Fortunately we played the dryline in northwest Texas where strong heating and good convergence would result in a couple of supercells forming by mid afternoon. We blasted down to Paducah, Texas from Childress and watched one storm produced two tornadoes. One was on the ground for about 5 minutes and the other about 10 minutes. They were fun to watch skipping across the countryside! Chaser convergence was horrendous this day, as expected being close to Oklahoma. We opted for another target later in the evening instead of fighting with the mobs in Oklahoma, but neither target panned out. Fortunately we got tornadoes this day as many, many chasers did not! Fun day, frustrating day and a disappointing day in the end. No lives were lost, very little injuries occurred. Good news for the plains!

May 17th Southwest Nebraska Tornadic Supercell

May 17th was an amazing day. Storms formed along a dryline in northwest Kansas and northeast Colorado and pushed into southwest Nebraska. One supercell approached McCook, NE and dropped a few tornadoes along the way. Strong wind shear, great instability and good surface moisture set the stage for this and other storms to form. The first tornado was quite pretty as it tracked just west of town. A couple more formed in the hills where roads were bad and thus not greatly visible from where we had to intercept them. None the less the storm was a very pretty supercell and long lived. It persisted for several hours before weakening north of Kearney, Nebraska.

May 7th Texas Tornado Warned Supercells

May 7th was advertised to be a strong tornado threat. In the end of the day, there really weren’t many tornadoes and none that were strong/violent. Too many storms would form and create a competition where none were able to be long lived tornado producing machines. We were able to chase 3 significant supercells, one near Stinnett, Texas, one near Amarillo and another near Tulia, Texas. The Tulia storm was the only one that produced, and even that was not significant. We arrived near Tulia a few minutes too late to see a weak bowl with a couple condensation fingers and also another small tornado. As we arrived, video caught a tornado in the distance about 10 miles away. The storm was high precipitation and very messy. We stayed with it as long as we could, however the caprock escarpment has few roads off of it and it made it impossible to stay with the storm. Later in the evening we chased 2 other tornado warned supercells in southwest Oklahoma near Hobart and Vinson. Fun day, a bit frustrating, but we still had several tornado warned storms to chase!
