June 10th Northwest South Dakota Tornado Warned Supercell

We expected a good day this day in South Dakota! Great instability, near 70 dewpoints, good shear and a dryline/outflow boundary intersection would set the stage for intense supercells late in the afternoon. By mid afternoon, a cluster of congestus formed in northwest South Dakota south of Buffalo. Soon several cells tried initiating there, with one dominant storm taking over the show. It quickly grew to 60,000 feet tall and became severe warned. Structure was decent and a wall cloud, complete with clear slot formed as it became tornado warned. This cell would weaken and intensify several times, but it never seemed a major threat to produce tornadoes. The tornado warning on the supercell continued for several hours, as broad cyclonic rotation occurred. It just never seemed like the rotation tightened enough to produce more than a weak funnel or two. By early evening, the storm lined out with a really pretty shelf cloud that had embedded mesocyclones that also became tornado warned. Still, a fun day, giving us many hours of chasing time on this pretty storm!

May 29th Northern Oklahoma Tornado Warned Supercell

May 29th took us to northern Oklahoma. An outflow boundary and advancing cold front across Kansas would provide the focus for supercell thunderstorms this day. Good moisture and extreme instability, as well as good wind shear would provide the ingredients needed for storms to sustain themselves and be intense. The first supercell formed over northern Oklahoma west of Alva and become severe. Later it would be tornado warned and produce a weak tornado. The structure was quite pretty and the storm exhibited decent rotation from time to time. However it could not focus in one spot and usually had broad rotation. Nonetheless, it was a good long lived supercell and provided us many photographic opportunities along the way for Tour 5 and the Photo Tour #2! Enjoy the pics!

May 28th Eastern Colorado Tornado Outbreak

May 28th had good potential. An outflow boundary laid across eastern Colorado from north of Seibert, Colorado to Colby, Kansas and points east. Great shear, instability, moisture and lift along the boundary, as well as the dryline extending south from Oakley, would allow numerous storms to form. A couple became tornado warned in far eastern Colorado. One particular supercell anchored itself north of Seibert along the boundary and became a tornado machine. We were on the scene early and watched as numerous tornadoes formed, with up to 3 on the ground at the same time (Total of 11!!). Several of the tornadoes were actually landspouts (nonsupercell tornadoes), however a couple certainly had mesocyclones and were therefore supercell tornadoes. It was an amazing sight for our guests to witness as we were able to get within a mile of a few tornadoes, and within a half mile of one stronger tornado! Please enjoy the photos from this amazing event!!!!!

May 23rd Roswell, New Mexico Large Tornado

It’s not often you wake up in Roswell, New Mexico with screaming southeast winds and 67 dewpoints. Low stratus clouds were racing west towards the Sacramento mountains! Even though mid and upper level winds were not particularly strong this day, there was sufficient speed and directional shear to get a supercell to form. We weren’t expecting tornadoes, but with high dewpoints and strong instability we knew the potential existed. Funny thing was most chasers were racing north to play a system in the central plains, but we couldn’t pull ourselves away from Roswell. In the end, we’re certainly glad we did! There wasn’t another chaser that witnessed what we did this day, with a quarter mile wide strong tornado under an amazing sculpted updraft! This cell produced huge hail as well and rolled across the countryside for hours all the way to Roswell. One of the most rewarding surprise days of 2018 for the tours!!! Enjoy the pics!!

May 18th Northern Kansas Supercell

A complex, but decent set up occurred on May 18th. A dry line, warm front and cold front would be big players this day, but the question was which would produce the best storms. The dryline fired up early and often producing numerous storms with huge hail. The cold front fired up in Colorado with clusters of storms moving into western Kansas. But it would be the warm front in northern Kansas that would produce the longest lived supercells, nearly anchored along it. Unfortunately, none would produce significant tornadoes, but a couple would produce hail baseball sized and as well as one landspout tornado. We chased a cell south of Oakley that would have pretty structure, tons of lightning and even a cone funnel that would could not determine if it touched down or not due to the angle it was from us. I fun and exciting day ended with a fantastic lightning show in Garden City, Kansas.

May 14th Southern Kansas Tornadic Supercell

May 14th took the May Minitour to southern Kansas. A storm formed near Arkansas City and anchored itself. Due to extremely high dew points and CAPE, the storm grew very large quickly. Wind shear was enough to start it spinning as well. It became severe and soon also was tornado warned. As the base lowered and a wall cloud formed, an elephant trunk shaped funnel dropped down and touched down for a couple of minutes before roping out. The storm maintained its structure for a couple more hours before it merged with a line of storms coming in from the west. A surprise event as it wasn’t forecasted, but nonetheless was pretty intense. Large hail also accompanied this supercell during its lifetime.

May 1st Kansas Tornadic Supercells

May 1st had a lot of promise. However there were certainly some issues with the set up. Storm mode was unclear near the front in northern Kansas and a strong capping inversion southward along the dryline could result is very short storm lives in that area. We started near Great Bend and jumped on a storm that formed northeast of Dodge City. It quickly became tornado warned. Based on initial visuals of the storm, it had little tornadic threat at that time. As the storm moved northeast towards Interstate 70 it really ramped up, getting tornado warned for nearly 3 hours. Rotation was visibly increasing and the structure of the supercell became quite nice. Unfortunately a left moving split further south came crashing into it and basically killed it. Other storms formed north and south, and opting for the usual tail end storm this day proved to be the wrong play. As the tail end supercell moved east away from the dryline, it showed a nice hook on radar and became tornado warned. As we raced south, leaving the messy northern play to get on the tail end storm, it weakened and eventually died. Before dying, it gave us a very nice look at the updraft as it became a low precipitation supercell. 9 out of 10 times this play works. However this day it did not as a cluster of storms north of the interstate rotated and one dropped a significant tornado.

Enjoy the photos as it was a pretty supercell!

October 6th Central Kansas Tornadic Supercell

October 6th had us running an on call tour. The setup looked higher end for a fall event. Good shear, abnormally high dewpoints, moderate CAPE and a dryline/triple point would set the stage for numerous storms to form. We jumped on the first storm southwest of Garden City, Kansas, which took us all the way to south of Salina, Kansas! It was the long lived supercell all high res models showed would form. Structure was decent and it certainly produced copious amounts of huge hail to softball size! As evening approached the cloud base lowered and the fun really started. Several funnel clouds formed and one tornado occurred from the storm. Motion was absolutely crazy with this supercell and I was pretty surprised it didn’t produce a large tornado! Nonetheless it was a fun chase day and great results! Drop us an email if you would like to be added to the “on call” storm chasing email list! They are QUITE successful!!

July 13th Central Alberta, Canada Tornadic Supercell

After our adventure in North Dakota on July 11th we knew we had to head well into Canada. A strong upper level low with great flow aloft, good moisture and instability, and lift along a dry line /Canadian Rockies foothills, would keep us in this region for several days. However, July 13th was by far the best set up in the area! We spent several nights in Red Deer, Alberta and chased west and north of there each day, capturing everything from supercells and tornadoes, great lightning, large hail, clusters of storms, and even a superb Aurora Borealis display on night!

July 13th looked like the peak of action and it certainly was. We targeted a boundary and foothills intersection west of Drayton Valley and we were on the storm as it developed west of there by mid afternoon. We watched the storm cycle several times until it finally intercepted better moisture and instability and took off. It rapidly intensified and started rotating. Soon the roar of the winds with the RFD of the supercell could be heard, followed by the winds from the tornado it produced. It started as a multivortex and morphed into a cone before it completely wrapped in rain. It was rated EF1, the strongest tornado in Alberta in 2017. The storm had fantastic structure, and throw in the canola fields of Canada and it was stunning! A great day and 4 day period for us in Alberta. Beautiful countryside there! Enjoy the pics and the Aurora as well!

July 11th North Dakota and Minnesota Tornadic Supercell

July 11th took as to eastern North Dakota. An advancing dryline, strong moisture return and extreme instability would set the stage for numerous supercells, some tornadic. We started the day just west of Grand Forks, ND as convergence caused cumulus towers to explode. It didn’t take long for severe and tornado warnings to be issued! We played with the first to do so northwest of town. It had decent structure and very large hail. A large wall cloud formed and spun strongly. An occasional shear funnel would occur, but nothing imminent to touch down. Soon, a supercell formed on the southern end of the line and quickly became severe. It developed a strong area of rotation and a hook on radar. we quickly dropped south to intercept the storm, driving through blinding rain and hail golfball sized. As we cleared the core, a large circular updraft came into view and it was obvious it was spinning strongly. A mulitvortex tornado occurred back in the core that we couldn’t see. It stayed on the ground for over 20 miles as it approached the Minnesota border.

We stayed with the storm all the way to northeast of Fargo is the structure was jaw dropping! At one point, the rain cleared enough to get a brief glimpse of the large tornado! (pic below) Eventually it weakened as upshear convection would form and interfere with the supercell. The lightning was extreme, intense and very close numerous times. Several times we had to get back into the vans for our safety and to keep our guests safe. Finally near sunset, we let the storm cluster go and headed west for what would be several days of chasing in Canada!
