We made a long hard dash from North Dakota to Illinois on June 22nd for what appeared to be a setup that had high tornado potential. Extreme instability, upper 70s dewpoints, strong wind shear and a warm frontal boundary would set the stage for a pretty decent tornado event. By late afternoon we arrived near Moline as storms finally got going along the boundary. Several supercells evolved along the warm front and several became tornadic. We intercepted two supercells that produced tornadoes, albeit weak tornadoes. Surprisingly there was only one tornado rated EF2 this day, which occurred well after dark. We chased along and north of I-80 from east of Moline to north of Peru, Illinois. Too many cell interactions made for a sloppy event, although the first tornadic supercell we intercepted near Hooppole had very pretty structure. I was sure this storm would drop a significant tornado. It produced a weak tornado that skipped along the ground for a couple minutes. As it continued east, it produced another tornado, a short lived multiple vortex tornado northwest of Peru. Later another supercell we saw in the dark produced the EF2 southeast of us. We couldn’t stay up with it. A long day, but a rewarding day for the tour!
May 24th Southwest Kansas Tornadic Supercell
May 24th had the best of both worlds. As Photo Tour #1 went to Colorado for its rewards, Tour #4 had a special day along an outflow boundary south of Dodge City. As Tour #4 moved north out of Oklahoma, hard cumulus towers formed along the boundary near Minneola. Soon, a storm emerged from these towers and would become an intense tornadic supercell as it drifted north towards Dodge city and spun like crazy. It took it awhile to really get going good, but when it did, a huge wall cloud formed, and started spinning wildly. The first of a dozen tornadoes would form of every shape, size and intensity, and at some point as many as 3 tornadoes were on the ground at the same time. Dodge city eventually came under a tornado emergency as a large multivortex tornado hit the west side of town. As the supercell moved north of town, many other storms formed and eventually turned into a huge cluster of severe storms that moved across Kansas. As that happened, we left the storm and went to Garden City for the night. An amazing day, with a dozen tornadoes from this storm and the fact both of our tours capitalized on the days potential was even more special!
May 24th Eastern Colorado Tornadic Supercell
May 24th was a day that had huge potential. Unfortunately there were two pretty clear targets. Play the upslope in eastern Colorado for what would certainly be a pretty tornadic supercell, or play southwest Kansas with high instability along an outflow boundary. Fortunately we had two tours going at that time, Tour #4 and also Photo Tour #1. After considerable discussion Photo Tour #1 headed for Colorado while Tour #4 headed for southwest Kansas. Both tours scored big this day! Upon arrival in Colorado Photo Tour #1 intercepted an intensifying supercell east of Denver. This storm would become a formidable supercell that would cycle multiple times and produce a half dozen tornadoes. As this storm approached an area south of Ft Morgan it began it’s tornadic phase as it intercepted better moisture and instability and the storm’s base came down. the Photo Tour, true to its name, found numerous beautiful places to photograph this supercell and it’s tornadoes all the way out towards the Kansas border. It kept producing tornadoes off and on the rest of the day and into the evening. Nothing wilder than night time tornadoes. Finally as it moved into northwestern Kansas, the Photo Tour dropped off it and headed to their night destination.
November 16th Texas Panhandle Tornadoes
November 16th was an amazing day and night. Numerous tornadoes occurred in Texas through Kansas, with the most intense tornadoes centered on two supercells in the Texas panhandle. We had the privilege of witnessing them both. A couple hours before dark dryline storms erupted and organized near dark, producing several strong tornadoes between Groom and Pampa, Texas. We watched an elephant trunk shaped tornado, followed by a large cone, then a wedge as storms raced off at 60 mph. An incredible way to finish the year for us as well as the guests that were on this tour!
July 19th Western Kansas Severe Storm
July 19th took us to southeast Colorado and southwestern Kansas. Although the set up wasn’t stellar by any means, there was enough shear, instability and moisture to support severe storms, including supercells. Mid afternoon south of Seibert, CO a supercell formed and tracked southeast. It eventually merged into a line of storms with embedded supercell structures as they marched all the way to Garden City, Kansas. Near the town of Tribune, Kansas on cell in the line spun pretty strongly and produced 80 mph winds, baseball hail and even a funnel cloud. This was a nice way to wrap up the Great North Tornado Hunt tour as the guests got to see a little bit of everything on this tour!
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!
June 25th Chugwater, Wyoming Tornado
June 25th looked like a mess on paper. Lots of moisture, good CAPE, good lift, but little shear would be the story this day. We headed up towards Kimball, Nebraska for the initial convention developing, only to be taken west towards Chugwater as numerous storms formed. Splitting and left moving storms were the norm, with a few showing rotation on the northern side of the cells. As we approached Chugwater from the east, a rope tornado formed and planted itself on the ground for about 3-4 minutes. It was something we really weren’t expecting but were pleasantly surprised to see! It was our 7th tornado on Tour 8 this year!
June 17th East Central Wyoming Tornado Warned Supercell
June 17th had a short wave trough moving across the northern high plains. Decent moisture and instability was in place to fuel significant storms. However a capping inversion kept storms from forming until late in the day. A storm complex moved out of Montana into eastern Wyoming, and it was this complex that developed significant rotation as a storm in front of the line became absorbed into it and caused it to rotate rapidly. A tornado warning was issued for the western Black Hills as the storm approached Beaulah and into the Spearfish area. The structure as dusk was quite nice and the lightning was amazing! One of the best lightning displays all season so far!
June 3rd Wyoming Supercell
June 3rd was a day we felt had decent severe weather and tornado potential. High CAPE, great shear and good lift along the higher terrain of the Laramie Range we felt would result in a few tornadic supercells. Unfortunately nature had other plans. Nothing of significance formed until just before dark and even then what happened is still up for debate. The storm spun nicely, and just as darkness hit several blocks and columns of scud clouds formed under the updraft, of which some folks called tornadoes. I am a pretty firm believer there were no tornadoes from this storm, but was certainly suspicious! Still, Tour 5 and the Photo Tour #2 had a great time with it!
June 1st South Dakota Supercell
For Tour #5 and Photo Tour #2, June 1st took us to the Black Hills area of South Dakota. Good upslope flow coupled with high CAPE values, would produce a very nice supercell storm that anchored itself to the east side of the Black Hills. This storm spun nicely, even tried to produce a tornado, but didn’t quite have enough low level shear to become tornadic. It did,, however, produce tons of very large and damaging hail to baseball size south of Sturgis. The storm persisted for several hours before decreasing in intensity just before dark. Both tours had a very nice treat on this day, and along with great structure, the storm produced some incredible lightning!
