June 12th, 2018 Oklahoma Panhandle Supercells
For the 3rd day in a row, we were able to
watch a storm from initiation all the way through it’s life cycle to final
collapse. We weren’t expecting much this day, and with strong instability but
minimal shear it looked like pulse storms were the best we could do. With two
potential targets: one just southwest of Wichita and the other on the Oklahoma
panhandle near Guymon, we left Topeka and headed for Wichita, stopping there for
lunch, and by that time the panhandle option looked more likely to verify so we
headed west on Rt. 400 out of Wichita.
After making the obligatory pass through Greensburg and a
stop at the metal sculptures in Mullinsville, we were forced to divert south at
Bucklin on word that there was an ethanol fire in Minneola and that roads were
blocked and people were being evacuated. We got down to Sitka and up Rt. 283 but
stopped before making the turn towards Meade to consider options as an updraft
with a broad flat base had gone up to our southeast and was already creating and
anvil. From where we stopped, we could see the smoke plume from the fire in
Minneola. Given the proximity of the updraft and the fact that the storm was in
about as good conditions as we were going to find, we went for it, intercepting
the storm at Protection. There were actually 2 updrafts, each with hefty
precipitation cores. The two updrafts were separating and the southern one was
becoming dominant, so we headed east then south on Kansas Rt 1., passing though
the core of the north storm (all rain) then crossing the state line and stopping
near Lookout, OK to observe the storm which now had a big core with hail and
decent structure. We continued to circle the barely moving storm, stopping on
Rt. 64 north of Selman, OK, then again a few miles farther down the road for a
better look at the updraft, and noted that the storm was developing a wall
cloud, so we continued west to get a better look at the hook echo area.
After an emergency fuel stop in Buffalo, OK we headed
west out of town and were able to get in perfect position to watch the
developing wall cloud ingest scud into the base. Another stop and we found a
great vantage on E0130 road and watched as the storm developed a big, almost
vertical tail cloud (it was not rotating and was not a funnel, though it was
reported as one), and soon the storm was a beautifully striated stack-of-plates
with a big inflow band and green hail glow in the vault. Around this time the
storm became very highly electrified, dropping bolts all over the place and
starting a big grass fire to our north, while sucking in copious amounts of
inflow from directly behind us, giving the vans a nice dirt bath. We continued
along Rt. 64, stopping for a look every few miles as the storm continued to be
almost anchored in place. At Rosstown we turned south towards Laverne after
another pause to watch the rotating storm to our north, then stopped and watched
the storm as it lost supercellular characteristics, though it continued to spark
like crazy. Once the bolts started hitting behind us, it was time to go.
At that point, we decided to head for the hotel, but had
to maneuver west to clear the still strong cores to the north. Twice along the
way the storm produced wall clouds and we diverted north, once towards Gate and
once toward Mocane to take a look. Near Mocane we were getting hammered by
outflow as we got very close to the wall cloud, but while it looked good for a
few moments, it quickly fell apart once we got there. We ended up hitting a hail
core north of Beaver, OK in violent outflow winds, and then passed through two
more cores before getting clear of the storms north of Liberal, KS and finishing
the trip to Garden City, KS where we stopped for the night.
A fun day that far exceeded our limited expectations!
Miles for the day were 605.
