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 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.

April 21st Western Kansas Supercell

April 21st didn’t look great on paper. However, storms erupted along a lee trough in far western Kansas and intensified as they moved eastward. A couple of embedded supercells would produce 70 mph winds and golfball sized hail. With the pretty Smoky Hill River badlands in the foreground, it sure made for a pretty scene! Bases of the supercells were quite high, as much as 8000 feet off the ground. Structure was pretty and lightning became frequent. We stayed with the storms until they weakend mid evening and then headed south for the night. I nice surprise chase for us on a day when it didn’t look very good at all!

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 9 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!

June 28th Southeast Montana/Northwest South Dakota Tornado Outbreak

An incredible day! The most significant tornado outbreak of 2018 to date occurred from one supercell this day! Southeast Montana and northwest South Dakota was the scene for this cyclic tornadic supercell that produced at least 8 and possibly more tornadoes in that area. The highest CAPE values I’ve seen in this area in 33 years of chasing occurred with 8000 joules of CAPE! Strong shear as well as mid 70s dewpoints, and throw in an awesome Black Hills Convergence Zone boundary and it would be only a matter of time before this supercell formed and morphed into the best storm of 2018! By mid afternoon several cells fired along the boundary and drifted north. All but one cell continued on this trek, with the one lone cell quickly becoming a supercell, which right turned along the boundary and turned into a beast! The structure was top notch and the tornado event that unfolded was incredible. Tornadoes of every shape, size and strength would form from late afternoon through sunset as the cell continued its slow march into northwest South Dakota. At one point we even had an anticyclonic tornado that developed on the south side of the updraft and raced directly towards us. Caryn would see it and take evasive action quickly as it passed in front of us. Then a large half mile wide wedge formed directly in front of us and roared across the countryside getting an EF3 rating! An amazing sight to behold!!! The storm continued into northwest South Dakota south of Camp Crook and continued producing tornadoes in the dark. Lightning would illuminate them making for some of the most spectacular storm photography this season! Please enjoy the pics!

 

June 26th South Central Kansas Tornado and Supercellfest

June 26th looked iffy. A mistimed short wave would fire numerous storms early in the day. However it also left an outflow boundary across southern Kansas. Extreme instability, mid 70 dewpoints and moderate shear would fuel and organize storms along the boundary. The first supercell produced a fast rope tornado that was on the ground for 1-2 minutes before dissipating. A second boundary intersected the outflow boundary just east of Wichita and that triple point would be the focal point for 4 distinct and strong supercells. They each produced very large hail to baseball size, copious amounts of lightning, a couple tornadoes and some of the best storm structure one would ever want to see!!! These supercells fired one after the other, and tracked east and southeast along the boundary. The last one of the day by early evening had insane structure and was firing off cgs every few seconds as it was tornado warned for hours! It would rage on for a few hours before dying off as a line of storms formed west. Incredible day for what could have been a total bust due to subsidence behind the early day wave! Enjoy the pics!

June 19th Prospect Valley, Colorado Tornado

June 19th had tornado written all over it. It didn’t disappoint either! Fantastic wind shear, high CAPE, good moisture for the high plains and upslope flow into the foothills provided all the ingredients needed to get tornadic supercells to form. An amazing sight, 3 significant supercell storms formed at the same time, situated about 50 miles apart. Usually the tail end storm is the cell you want to target, however, an old outflow boundary existed in which the middle cell developed on. It would be that cell that would go on to have amazing structure and produce the Prospect Valley tornado. All 3 storms would become tornado warned during their lifespans. The middle storm we watched grow from a smaller storm to a well structured tornadic supercell as it crossed I-25 and moved eastward. Various wall clouds, each time showing rotation, formed until finally rotation tightened to produce a tornado. A long snaking tornado was on the ground for nearly 10 minutes before roping out. After the tornado, the storm still spun as it moved across eastern Colorado before dying south of Ft Morgan. At that time, we blasted south to Limon and points east as the tail end storm took over the show. It also was tornado warned and may have produced a rain wrapped tornado north of Genoa. Structure was beautiful HP supercell, and it also was highly electrified. By early evening the storms lined out as they moved into Kansas producing high winds and heavy rain. A fantastic day for the tours as nature gave us quite a show!

June 18th Notheast Colorado Supercellfest!

Days like June 18th don’t happen very often.  With good moisture, shear and instability, it was a pretty good bet supercells would form. However, we didn’t anticipate the shear number of supercells that would actually form! A boundary laying east/west across the northern Denver metro area extending into northeast Colorado would provide the needed focus for storm development. One supercell after another formed and tracked along the boundary.  Every different type and structure of storm occurred and made for a photographer’s delight! Sculpted updrafts with good lightning, wall clouds, colors, possible tornadoes, and hail happened! Storms would rage on through the late evening hours before diminishing just before midnight. SLT co-owner Caryn Hill’s intercept of the Roggen, Colorado storm superseded the structure shot she got from the night before near Otis, Colorado! Absolutely stunning sunset supercell! Please enjoy the photos! They were gorgeous!
