June 12th Wyoming and Nebraska Tornadic Supercells

June 12th had the potential to be a record breaking event for eastern Wyoming, as well as the Nebraska panhandle. At the end of the day numerous tornadoes formed across the landscape! Very high moisture, extreme CAPE, very strong wind shear and upslope into the Laramie Range would cause several supercells to form. We chased the first supercell of the day, which produced a couple of tornadoes near Lingle, Wyoming. This storm was tornado warned for many hours as it moved northeast across eastern Wyoming and western Nebraska.

Later we would drop south towards Scottsbluff, Nebraska and catch a tornadic storm that came out of Colorado (See the next chase account from SLT co-owner Caryn Hill!!!!!). We witnessed 3 tornadoes from this storm. Later in it’s life cycle, it would become one of the most photogenic supercells of 2017 as it rolled across the Nebraska Sand Hills headed for southern South Dakota where it dissipated after midnight. For an event to be this strong, this far west, it was almost unprecedented. SPC even had a Moderate Risk for eastern Wyoming, only the second one in history! They were also forecasting strong tornadoes, which did occur. Hail and lightning in these monster supercells were incredible as well! Enjoy the photos!!!!

June 27th Southwest Nebraska/Northeast Colorado Tornado Warned Supercells

The first day of the Reunion tour provided a decent high plains set up. Upslope flow into western Nebraska would push 60 dewpoints along a boundary as moderate westerly mid level winds would help generate enough wind shear for supercells. Two such storms formed along the northwest/southeast oriented boundary and would produce giant hail to softball size. Both supercells were tornado warned with the second storm producing a confirmed tornado near Eckley, Colorado. Structure was decent as well. We came back through the area the next day to find thousands of acres of cropland shredded to the ground, mostly corn. Sometimes hailstorms can produce more significant damage than a tornado can. This was the case with these storms.

July 18th Nebraska Supercell and Funnel

July 18th took our Great North Tornado Hunt towards the North Platte area. Modest shear, great convergence, good instability and moisture would result in numerous storm developing. We targeted a cell northwest of Hershey that ended up anchoring itself there for a couple hours as it intensified. The structure on the storm was quite nice, and as it moved towards Hershey, a long slender funnel formed near the clear slot of the supercell. We stayed with the storm until it decayed near dusk. Overall a great chase day and results for the tour. Something about Nebraska in July produces very pretty storms often!

July 22, 2014 – South Dakota Beautiful Supercell

As if often the case on this particular tour, storm structure and quality was amazing this day. We started in Rapid City and spent the entire day with one supercell that formed early afternoon. This storm rolled over the Black Hills and turned due south into northwest Nebraska where it became tornado warned. It did not produce a tornado, but the structure was simply a photographers delight! It produced very large hail and an incredible amount of lightning. This was our last tour day of 2014, and a fantastic way to finish the season!

June 16, 2014 Northeast Nebraska Tornado Outbreak

First, our heart felt sympathy goes out to those who suffered losses on this day. When we awoke on the morning of June 16th, I had butterflies in my stomach. I knew there would be potential for strong to violent tornadoes in Nebraska. Unfortunately those fears were realized as at least a half dozen strong or violent tornadoes would ravage the area east of Norfolk. The town of Pilger would be particularly hardest hit. We spent a good chunk of the day around Columbus analyzing data and watching things unfold. With a temp of 83 and a dewpoint of 78, stiff east winds buffeted the area along a warm front. Conditions were ripe for powerful supercells and tornadoes. Mid afternoon storms formed along and north of the warm front. They moved into colder air and weakened. We knew it wouldn’t be long before storms would form along the warm front and ride it eastward with extreme shear. Southeast of Norfolk the first tornado formed and tracked near Stanton. Another tail end cell developed and produced the rest of the tornados this day with twin EF4 tornadoes destroying Pilger and other locations northeast of there. We watched from the back side of the tornadoes, about 1-2 miles east of us as the event unfolded. An event we’ll never forget! Tornadoes of every shape, size and strength occurred. The last time twin violent tornadoes occurred so close together was nearly 50 years ago! Amazing, and devastating to say the least!

June 13, 2014 – Nebraska Beautiful Supercell

June 13th appeared to be a decent chase day. An approaching shortwave would induce a lee cyclone that would in turn draw moisture northward into western Nebraska. A developing dryline would be the focus for several storms that would form. We played the tail end storm as it developed eastward and spun very hard. Due to fairly high cloud bases, this storm became a tad outflow dominant and never could produce a tornado. It was tornado warned twice in it’s life cycle. It did have very pretty structure and also produced very large hail and high winds. The sandhills of northwest Nebraska provide an amazing foreground for storm photography!

May 11, 2014 – Southern Nebraska Tornadofest

What can be said of this day! Caryn ran a private tour and this was one of the final days, and an amazing event it was! A warm front lay across southern Nebraska, while a dryline extended south from the surface low. By late afternoon several storms formed north of the warm front in the cold air where there was not a capping inversion in place. Finally the triple point storm formed, and rapidly became severe. It didn’t take long for the supercell to nearly anchor and become violently tornadic. It produced several tornadoes, including a huge wedge near the town of Sutton, Nebraska. It also produced numerous tornadoes Caryn and the tour were able to witness, of about every shape and size imaginable! Roger was in Oklahoma City with a new tour arriving this day and managed to run north into Kansas and capture a couple very pretty supercells, one of which likely produced a brief tornado.

October 4th, 2013 – Northeast Nebraska/Northwest Iowa Tornadoes

October 4th looked crazy on paper. Great shear, super lift, great instability and moisture for Oct spelled big trouble for the folks in eastern Nebraska and western Iowa. We left early morning in heavy snow and fog from our home in Colorado, and headed towards Lincoln, NE where we’d decide to head north or east. A supercell formed north of Columbus and was moving away from us so we decided to play the patience game for something further east. Soon a wedge tornado formed from the first supercell and we were feeling pretty bummed. Finally our storm got going as it crossed into western Iowa, dropping a large tornado west of Sloan. After an occlusion, a second, third and fourth tornado formed and the latter becoming a large 1.5 mile wide wedge heading near Climbing Hill northeast towards Cherokee. We had to stop the trip as we encountered a destroyed farmstead north of Climbing Hill, where our search resulted in no injuries, except farm animals. Fortunately, no fatalaties occurred that day, but a lot of destruction of property. Here’s a 10 minute video from this day:

July 9th Central Nebraska Tornado and Supercell

July 9th appeared to be a marginal set up. Shear wasn’t very good, and moisture was fairly lacking. However, moisture pooled along a boundary and winds on the north side of the boundary were easterly, giving a bit of enhanced low level shear. By mid afternoon, several storms developed, with one cell north of Cozad becoming a monster supercell very quickly. The rapid development stretched low level vorticity very fast and a nonsupercell type tornado formed. It persisted for about 5-7 minutes before dissipating. Please excuse the poor quality of the tornado shots as they were taken out the windshield while moving. Other cells become photogenic (and severe) as we chased till mid evening.

May 17th Hyannis, Nebraska Tornado Warned Supercell

What a surprise this day was! After a cluster of weakly organized storms formed over the sandhills early afternoon, another storm, a rotating supercell, developed near Hyannis. Shear increased as evening came and so did the structure! A very pretty tornado warned supercell that was quite photogenic and electrified continued until near midnight.
