June 21st Palmer Divide Briefly Tornadic Supercell

We weren’t expecting anything significant on June 21st. However, as often happens in the upslope regions of Colorado combined with terrain features, a decent supercell formed north of Colorado Springs along the Palmer Divide. Good directional shear due in part to strong easterly winds helped the storm to organize and rotate. As the cell approached the town of Kiowa, the low levels started spinning strongly. You can see a hook forming visually and rotate pretty rapidly. A tornado warning was issued by the NWS and soon an area of rotating debris was seen under the hook area of the storm. This weak tornado only lasted a couple of minutes.

As the cell moved further east, it encountered less surface moisture and instability, which caused it to steadily weaken and eventually dissipate east of Limon. Several other storms initiated in the cold side of the first cell’s outflow and never could really intensify for long periods. A fun chase and right in our backyard.

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!

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 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 1st Seymour, Texas Tornadoes

May 1st was a great setup. An outflow boundary lay in northern Texas with 70 degree dewpoints to its south. High CAPE, strong shear and lift along the boundary would cause several tornado warned supercells to form. However, only one would produce any tornadoes. We sat in Seymour for a couple hours waiting for initiation to occur at the triple point just southwest of town. Soon, a storm developed and shot to 55,000 feet in height. We blasted south through intense rain and lightning only to be greeted by the first tornado about 7 miles to our west. Poor road networks prevented us from getting close to this beauty! It lasted about 10 minutes and dissipated. Not long afterwards, a new meso formed to the east and started rotating intensely. A multivortex tornado touched down and lifted several times before a slender cone tornado formed. It bounced around the ground for a few minutes before lifting. We were about 1 mile from it when it occurred! You could hear the waterfall sound of the rear flank downdraft winds as it crossed to highway just north of us. Eventually the storm weakened as we blasted west to another tornado warned supercell. This storm became high precipitation quickly, but it tried hard to drop another tornado to our north. I cannot confirm if it did or not based on our position, but it spun wildly. Enjoy the photos!

April 30th Red River Area Tornadic Supercell

A day of big hopes was April 30th. Great moisture, high CAPE and strong deep layer shear would set the stage for supercell development. We started the day in Wichita Falls, Texas only to move across the Red River into southern Oklahoma. It appeared that storms would form along a cold front and intensify as they crossed the river into Oklahoma. We played with a cell near Randlett, OK initially, which never did much. It was severe, but never looked like a threat to produce tornadoes. Eventually a couple of cells formed in front of the cold front and rapidly became severe. One storm near Byers, Texas dropped a significant tornado just across the Red River from us. We figured since the storm was moving northeast at 35 mph that we would stay on the Oklahoma side of the river (since there are FEW crossings!) and wait for the storm and tornado to approach. To our much surprise the tornado dissipated and the supercell died as it came to us! There was NO reason for the NEW supercell to abruptly diminish! However it did, but not before we were able to get some photos of the structure and of the tornado in the distance. It was only about 8 miles away when it’s demise occurred. Fun day, frustrating day, but we all enjoyed ourselves!

April 3rd Southwest Oklahoma Supercell

April 3rd took us to southwest Oklahoma to film a commercial for Chevy Silverado trucks. After 2 days of intense filming in Colorado, we took the film crew to southwest Oklahoma in search of a supercell storm. It did not disappoint! Late afternoon a storm formed southwest of Wellington, Texas and moved into southwest Oklahoma near Hollis as it intensified into a formidable supercell! Fantastic structure, hail the size of tennisballs and nice lightning greeted us and the film crew. We stayed with the storm till sunset south of Snyder and then let it go. The tv crew was astonished at the sight of the supercell and came away with fantastic footage to use in the commercial. It will air late spring first on CNN and then later on other channels.

July 10th Killdeer, Saskatchewan Canada Tornadofest

July 10th lived up to the potential forecast models showed! A strong shortwave trough would traverse across southern Canada and Montana, as a dryline/cold front and associated warm front would slide slowly east. Strong shear, deep moisture, high CAPE and several boundaries would be the focus on severe storms. The question would be whether or not they would be isolated or clusters/linear. Fortunately a cluster of supercells formed over southern Saskatchewan and the tail end cell anchored along the warm front west of Killdeer. This storm would become a tornado machine as it produced at least 11 tornadoes we counted. More may have occurred as multiple occlusions occurred and some were quite messy with low visibility. This was one of the best tornadic events we’ve witnessed in Canada in 20 years of tours! Fortunately the tornadoes stayed over rural countryside and did little damage. A couple of these were quite strong. This storm slowly moved east riding the warm front all the time and eventually was choked off by outflow from a linear complex over Montana. Amazing event and a great way to end our tour season! Enjoy the photos and video stills!

July 9th Northeast Montana Tornadic Supercell

July 9th had big potential. It wasn’t clear whether that would be across the international border into Canada or if storms would right turn along a warm front into northeast Montana and northwest North Dakota. Fortunately, for ease of chasing, storms crossed into the US and gave us quite a show! An intense supercell cycled and really ramped up as it crossed north of Plentywood, Montana. Due to high CAPE, strong deep layer shear, dew points in the lower 70s and the aforementioned warm front, the stage was set! This supercell became a monster, the storm of the day, as it rolled through Plentywood, MT and into far northwest North Dakota. Huge hail to baseball size, microburst winds of nearly 120 mph and an EF1 tornado that hit Plentywood, would be the highlight this day. A second supercell soon followed the path of the first and had just amazing structure as it rolled through Plentywood. Highways ended up being blocked due to debris from downed trees, power lines and houses through town. Fortunately there were no fatalities. Check out the photos below. Enjoy!!!
