Chase Trip Day One forecast (June 16): Two targets >> first is near the colorado/kansas/nebraska tri-border and second is south-central KS
Today could be a fairly wild day for severe weather on the central and
western plains. This is the first of a number of chase days for me as
I am on AL until the 28th. I am torn between two targets right now.
Target #1 is extreme southwest Nebraska/northeast Colorado/extreme
northwest KS border region -- say Benkleman, Nebraska to Wray,
Colorado. I will be waiting for fresh storms in the 6-8pm time frame
in this area... as there will likely be storms by 4pm coming off the
Laramie Range given the upper tropospheric jet streak dynamics in play
farther northwest (right entrance region of jet). All the high-res
mesoscale models want to convect up there early... and by 7-8pm, I
fear that the western Nebraska Panhandle may already evolve into a
non-supercell severe cluster... so playing farther southeast may be
best.. right at the northern reach of the heat plume where 60s
dewpoints pull back to the west-north west north of the sfc low.

Target #2. South-central Kansas. Very interesting setup here. The
well-forecast MCS is underway as of 1140 UTC over northern KS/southern
NE. The NAM12 all along, and now the high-resolution WRF models,
indicate a signal for development of a honking, nearly stationary
supercell at the dryline/OFB intersection somewhere from like
Hutchinson to Wichita. While the mid and upper tropospheric winds
will be 20-30 knots in this area, the directional shear will be very
good and you gotta love the sfc-850mb flow...yielding very interesting
hodographs with a Bunkers storm motion near the origin. This target
is very tempting (despite the 100-degree heat). There very well could
be a tall tornado from a supercell in this environment if the dewpoint
is > 65F in this area.

At this point, I am kind of leaning toward Target #2 actually... but
this is as of the time of this post before 1200 UTC.

Supercell structure from the Garden City/Cimarron/Dodge City high-based storm of 15 June 2011
I followed this storm to the east-southeast from as far west as about
15 miles northeast of Garden City. The light was fairly harsh to
shoot in with the low sun light and the high base of the storm which
was not precipitating a whole lot. After sunset, a new cell on the
southern end took over and produced a very impressive, dense
precipitation core looking to the southwest in twilight. The color
was revealed by this precipitation core was incredible! Pink and
orange colors glowed from the precip core -- a rather surreal scene
indeed and extremely photogenic.

June 16 Chase Summary and Images (Day 1): Southwest Kansas -- Bucklin to Greensburg HP Supercell
The day started out with two targets in mind: One was around
northeast Colorado and adjacent far southwest Nebraska/northwest
Kansas and the other was along an outflow boundary from morning storms
with a minor disturbance in the mid levels moving into far southwest
Kansas. I decided to chase the southern target and had the luxury of
hanging out at my house most of the day to watch the atmosphere unfold
(both visually and remotely on the internet). Mid level altocumulus
(accas) and showers were developing over Baca County early in the
afternoon and were moving northeast into KS. The HRRR model was
aggressive and persistent in developing this area of mid level accas
and virga/showers by late in the afternoon. Soon, it became evident
that new surface-based cumulus was forming to the west and southwest
ahead of the accas. Storm chasers Brandon Sullivan and Mike Scantlin
stopped by my house to look at data, since this was their target area
as well. Separately, we departed south toward Minneola and along the
drive, towers were forming southeast along the outflow boundary.
Observations showed 66-67F dewpoint air on the northeast side of the
outflow boundary. The problem was, that surface-based air had high
inhibition since it was some 15 degrees cooler than the 104-106F heat
on the other side of the outflow boundary. This was a problem. These
storms that formed on the outflow boundary quickly moved northeast and
were essentially elevated above the outflow boundary. The storms
looked like crap, visually, and strong 25-35mph southeast winds...
very moist... were essentially blowing right underneath these storms
(one was north of Greensburg and the other was southwest of Pratt.
The storm northwest of Greensburg actually produced a small mid-level
funnel cloud, but it was totally benign. I saw this storm going
nowhere, and at the time, I was actually becoming a little more
interested in the Pratt storm since it was getting more aggressive on
radar... plus it was tail-end (even if it was slightly elevated).
Sometimes slightly elevated storms can transition to surface based if
the updrafts get extremely intense. I went to Pratt... got to the
other side of the storm...and it too looked like crap. This was
frustrating.

Then, in no time, the Dodge City storm all of a sudden back to the
west (which I had not originally gone after because I thought it was
becoming a linear piece of garbage) was taking on a different
character. I drove back west through Pratt and on my way to
Haviland-Greensburg. I arrived at Haviland and observed some fairly
decent HP supercell updraft structure to my northwest. I photographed
this for a little bit then continued on west to Greensburg as
supercell was really getting its act together near Bucklin. I drove
west on Hwy 54 to near Mullinville where I set up the tripod for the
first series of images. I then back-tracked to Hwy 183 at Greensburg
and shot south about 7 or 8 miles to a nice viewing point along a
county road. My best images of the day came from this spot with
fairly classic supercell storm structure. The storm went on to
produce a menacing lowering/wall cloud, but I never noted any
significant cloud base rotation (plus, the visibility back in there
was rather poor). After this sequence of events and the storm
continuing to move east... I decided to head south to the
Kiowa-Comanche county line and go east a bit where I took my last set
of images from along the county line east of Hwy 183. The supercell
structure was becoming a little bit less impressive and the rear flank
gust front shelf cloud was kind of overtaking the structure from my
perspective. I then proceeded to let the storm go by me as I drove
back north toward Greensburg on Hwy 183. As I approached Greensburg,
I was buffeted by 60+ mph east winds behind the storm... which was a
difficult cross wind to drive in (even at a reduced 50 mph). By this
time, the sun had already set, so I was too late for behind-the-storm
photography in waning sunlight. There were some nice anvil zits
(lightning) behind the storm, but low clouds were interspersed among
the storm's backside faint mammatus/lightning and unfortunately did
not make for good photography. I ended the chase at this point and
headed back home.

Chase Trip Day 2 - June 17. Target: Eastern Colorado downwind of the Palmer Divide for early-mid evening high based supercell potential.
Day 2 target I will first drive out to Lamar for lunch and then
re-evaluate from there. More than likely I will drive northeast
toward Limon for the first storms coming off the Palmer Divide. CAPE
will be marginal at best for severe weather/supercells with 800 to
1200 J/kg expected in marginal moisture of mid 40s to near 50
dewpoint. The deep layer shear is great, however, and the early runs
of the HRRR model depicts supercell looking simulated composite
reflectivity "blobs" in east-central Colorado later this afternoon.
So there is some hope.

Outlook: Day 3 (Saturday) will be in the same general area, so
wherever I end up tonight, I will probably lodge near there for the
night (Burlington or Goodland?) instead of driving back to Dodge only
to go right back out there the next day. After Saturday's chase, I
will drive back to Dodge City to pick up Jay Antle who will drive to
my house late Saturday night or early Sunday morning. Sunday and
Monday look like definite chase days as a nice trough approaches the
plains. Tuesday could be another chase day farther south along the
trailing front in northwest Texas/southern Oklahoma or it could be the
beginning of a nice long drive to the northern High Plains (Montana?)
to get ready for the next Pacific jet to impact the northwest yielding
chase opportunities way up northwest by Thursday of next week. This
is still speculative, though, with a lot to potentially change (and it
probably will).

chase update 145pm cdt. in Lamar, CO just had lunch will head northwest toward Punkin Center/Karval area (S of Limon) will shoot for southernmost organized storm

June 17 Chase Summary and Images (Day 2): Eastern Colorado to Southwest Kansas -- Long-lived High Precipitation Supercell from Calhan, CO to Tribune, KS
Day 2 was a successful day of storm chasing and photography. My
target was southwest of Limon where I thought the southeastern-most
storm would form and thrive in unrestricted east-southeast inflow air.
Once I arrived at the target area along Hwy 94 near Rush, CO, a storm
was already in progress. I first went north on a county road north of
Rush about halfway to Simla when the storm took on supercell
characteristics. It had classic structure at first and revealed a
slowly rotating wall cloud for a little bit as it approached my
location north of Hwy 94. It then became outflow dominant quickly as
it continued east-southeast south of Limon. I followed it east along
Hwy 94 stopping occasionally to photograph the shelf cloud structure
of the rear flank gust front of this now well-established HP
supercell. Some of the best HP supercell structure came when I
stopped at a location a couple miles northeast of Wild Horse on a
county road photographing the storm with a dilapidated looking wheat
field in the foreground. I then continued to Kit Carson and stopped
again a mile south of town to photograph the multi-tiered shelf cloud
and updraft of the HP supercell with the town in the foreground. I
continued south to Eads and met up with the storm again east of
Sheridan Lake. At this point, I went north and east on some dusty
farm roads with the menacing storm to the north. I stopped for a
quick "grab-and-go" shot of some outflow/shelf cloud structure and
then got my butt back south to Hwy 96 near Towner, CO. I stopped one
last time to photograph the incoming dusty storm with the town of
Horace in the foreground then let that storm finally go after chasing
it for 160 ground miles from roughly 2100 UTC (4:00pm CDT) to 0145 UTC
(8:45pm CDT).

To complete the chase, I stopped to get gas Syracuse, KS then
proceeded to follow another storm (to the southwest of the original
long-lived supercell) east to Lakin. At Lakin, I let the storm roll
over me with some pea size hail and 50 mph winds. Once the storm
cleared, I drove east of town about a mile or two and photographed
some amazing anvil/updraft lightning complete with mammatus and a
pristine clear sky in the storm's wake with stars visible. This was
quite the treat to complete this exhaustive chase! I drove back to
Dodge City watching a fairly amazing lightning display along the way
home.

Chase Trip Day 4 (June 19) Summary: Northeast Colorado target failure leading to miss of Benkleman/McCook supercell from the inflow sector
Below are a few images from the backside of the Benkleman/McCook
supercell from south of McCook looking east-northeast at around the
time of sunset. It was all around a frustrating chase day as our
target around Last Chance to Akron failed to produce supercells.
Supercells did form east of the target and we were caught too far west
playing catch-up for a long time... and never really getting into any
good viewing perspective of the storm from the east/southeast side.
We ended the chase near Red Cloud and headed south to Wakeeney, KS for
the night. Managed to get a couple images that were decent from the
backside of that nice supercell, but the results of the day could have
been far better if we made a better forecast.

Chase Trip Day 5 (June 20): Target KS-NE border early afternoon Stockton KS to Alma NE then north toward Central Nebraska late afternoon into evening.
We sit in Wakeeney this morning with an elevated supercell producing
baseball size hail near Oakley at 7:30am CDT. It's going to be one of
those days. There could be a tornadic supercell as early as noon or
1pm not too far north/northeast of where we sit this morning in
Wakeeney. It could be a long, tiring day of storm chasing.

Mon, 20 Jun 2011 12:43:45 -0500

chase update 645pm. well, it is all shelf clouds around here in far southeast nebr/northeast ks.. so we will jump ship and call this a chase day and head back to dodge
After some discussion, we have decided to call both Tuesday and
Wednesday down days with the potential for resumption of chasing with
a better looking pattern by Thursday and especially Friday.. Will try
to get the windshield replaced tomorrow in Dodge then depending on how
long that takes, may head to northeast new mexico for wednesday's down
day for some sightseeing and whatnot.

Below is a map I have constructed of the route Jay and I took as we
followed and documented the significant, long-lived tornado from
northern Graham County into Norton County, Kansas. Also on this first

Summary & Images (part 2)
The sequence of images below are during a 1 minute and 40 second
period of time as the tornado strengthens rapidly and changes
character significantly as it approaches Highway 283 north of Hill
City. White specks in a couple of the images are distant giant hail
stones falling in front of the tornado(es). The lower left image

Summary & Images (part 3)
After driving north a couple miles on Highway 283, we stopped again to
photograph the now well-established wedge tornado after it had crossed
the highway behind us. This is looking south-southeast. Right about
the time of the third image in this sequence (2:03:30) is when we
turned east on Highway 9.

Below are the sequence of images of the large tornado approaching
Highway 9 as we race east to get east of it's path. At 2:06pm, we
were in the tornadoes path at around Edmond, KS and maybe a mile or so
east. We safely made it far enough east before the tornado(es) made
it to the highway and the last image of this sequence of images at
2:12pm shows the incredible rain and hail-wrapped beast to the
west-northwest by only a few miles.

Chase Trip Day 7 (June 22): Drive day to tomorrow target near Billings, MT. Leisurely drive up I-25 reaching Casper, WY by 7pm MDT or so. May be a Bighorn Mts storm early evening to observe

Wed, 22 Jun 2011 23:37:25 -0500
In Buffalo, WY this evening (June 22) after a 700 mile long drive starting from Clayton, NM. Nice steak dinner in Casper, WY. South-central MT tomorrow

Thu, 23 Jun 2011 09:41:51 -0500
Chase Trip Day 8 (June 23): Today is a chase day in south-central or central Montana. Will head to Billings by early afternoon and re-evaluate and go north or west from there.
Starting off the day in Buffalo, WY where Jay and I stayed at the Big
Horn motel... a favorite that Vince Miller and I frequented during
2007 and 2008 June chase trips.

Brief Summary of Chase Trip Day 6 and Day 7

Day 6 -- Tuesday June 21. Jay and I hung around Dodge City most of
the day as I had my windshield replaced out of my Jeep due to a very
large hail stone impact. We then decided to drive to Clayton, NM for
a couple of reason. A) we love Clayton and love green chili and we
heard that the Eklund Hotel and Saloon had re-opened. Jay and I were
very pleased to find out that that indeed is the case and we actually
stayed at the Eklund (despite $$). B) There was a chance at northwest
flow storms in eastern New Mexico and the TX Panhandle per the GFS and
the NAM that we were watching as a potential to chase for Day 7
(6/22).

Day 7 -- Wednesday June 22. After it became clear that the northwest
flow chase potential had dried up, we decided to make this a drive day
to what looked like a much better setup for severe storms over
southern Montana. We left Clayton mid-morning and drove north all day
reaching Casper early evening for a steak dinner then on to Buffalo,
WY for the night.

Chase Trip Day 9 (June 24) Summary: Part 1 -- Casper, WY Supercell, Guernsey left split storm, followed by Laramie Peak storms
Summary & Images (part 1)
Jay Antle and I intercepted the first storm of the day as we drove
south out of Buffalo, WY. We met the first storm near Casper and
followed it southeast along I-25 stopping occasionally for
photographs. At Douglas, we decided to continue south as the southern
end of the storm was supercellular and another more linear storm was
beginning to tear off more toward the east and northeast. This
northern storm actually ended up becoming dominant as it rolled east
through Lusk and Harrison (our original target area) and eventually on
into northern Nebraska later in the evening. Other storms forming off
of the southern Laramie Mountains were moving northeast while the
supercell we were following was moving southeast. This interacted
with the southern storms and the process ended up being destructive to
pretty much all convection in terms of supercell structure. A cool
looking left-split storm moved northeast quickly toward Guernsey which
had a pretty white hail core to our southeast. We let all this stuff
try to sort itself out around Guernsey, but it never did and it all
eventually just died. New storms were forming over the Laramie
Mountains near Laramie Peak which caught our eye, so we went back west
to the interstate at Dwyer Junction. We drove north a few miles and
stopped to watch one of the storms roll off Laramie Peak. The
cloud-to-ground lightning was infrequent, but I managed to capture one
of the flashes to the west with Laramie Peak in the background.
Afterwards, we followed this weak storm east as it sputtered along the
way to Torrington and Scottsbluff... where we ultimately called it a
chase and had mexican dinner. While eating, a new supercell formed
just southwest of Scottsbluff, and we took a peak outside every so
often during meal to observe the incoming storm. We drove back to the
motel and watched the storm roll over us with some 1/2" diameter hail
at our motel on the east side of Scottsbluff. Later in the evening,
new storms formed to the west of Scottsbluff which we set out to chase
for lightning photography. See part 2 below.

Chase Trip Day 9 (June 24) Summary: Part 2 -- Scottsbluff, NE area late night supercells
Summary & Images (part 2)
Jay and I noticed new storms forming west of Scottsbluff at around
10:00pm CDT. We packed up the gear again and set off, first, for just
west of town as we tried our hand at lightning images with the first
storm. It was moving east fairly quickly and we followed it east of
town and let it go east of us. More storms were forming, though, to
our south and also again back to the west. We drove south from
Melbeta through some of the bluffs southeast of Scottsbluff and
stopped for awhile to photograph some nice lightning-illuminated storm
structure of multiple cells oriented west to east to our north.
Mammatus was visible through some of the flashes in the wake of the
first cell in this sequence. More organized storm structure was
photographed through lightning flashes with the bluffs in the
background through about 12:20am CDT. Once the storm structure lost
some of its interest photography-wise, we drove back to Scottsbluff.
This was a fun late-night shoot!

Chase Trip Day 10 (June 25) Summary: Kimball-Sidney, Nebraska high-based supercell
Summary & Images (part 1)
Jay Antle and I intercepted an awesome supercell on Day 10 of this
storm chase trip. Our target was east of the Laramie Mountains as
fairly high CAPE was lurking over the eastern Nebraska Panhandle with
upslope winds increasing by late afternoon and early evening. After
spending some time at Scottsbluff National Monument early in the
afternoon, we set sights on mid afternoon storm development northeast
of Cheyenne. The first storms developed over northern Laramie county
and we drove southwest from LaGrange along Hwy 85 to observe these
first storms. The storms sputtered along as they moved east toward
the Harrisburg area. At Harrisburg, we had to make a decision what to
do next. There were storms trying to get organized up in the Lusk, WY
area well to the north, but what caught our eye more were new towers
forming to our southwest along the outflow boundary left behind from
the first storms that we were following. As a result, we went south
to Kimball. This ended up being a very good call as the group of
towers to our west-northwest organized into an awesome supercell. We
navigated farm roads northeast of Kimball with the storm updraft to
our west-northwest. We tried to remain in the sweet spot
east-southeast of the updraft about 8 to 10 miles to get the good
structure shots of the storm. The supercell cycled through numerous
mesocyclones with a number of wall clouds and occlusions observed. We
also saw a number of dusty spin-ups, mostly caused by RFD hitting the
surface, but one or two of them were fairly intense and cold have been
tornadic. Several persistent mid-level funnel clouds were also seen,
particularly as we were driving south back to Highway 30 northwest of
Sidney. But it was the structure of the storm itself that stole the
spotlight with amazing hues of aquamarine. The bell-shaped nature of
the updraft and the vault just downstream of the updraft itself were
amazing. As the sun was getting lower in the sky, we dropped south
toward the Cheyenne Ridge south of Sidney. More laminar banding of
the updraft was evident, taking on the classic "mothership" appearance
to the northwest. Anvil lightning was frequent overhead with the
persistent, harmonic sound of grumbling going on way up in the upper
troposphere. We continued to stay ahead of the storm south and east,
through the very large Peetz wind farm, and eventually down to Hwy 138
with darkness increasing after sunset. The supercell eventually faded
away late in the evening as it approached the Julesburg, CO and Big
Springs, NE area, but not before putting on a nice display of anvil
zits (short, intense spurts of lightning within the anvil). This
ended up being, for me, the most photogenic supercell of the 2011
season to date.

Below is a sequence of images of the early stages of the supercell
from north of Kimball to northwest of Sidney while we were on the farm
road grid north of Hwy 30:

Chase Trip Day 11 (June 26) Summary: Shelf cloud in the Sandhills (near Hyannis, NE)
Summary & Images (part 1)
Overall, this was a rather frustrating day in terms of supercell
interception. A day that started out with a lot of hope and potential
with very high moisture leading to extreme CAPE over western Nebraska
turned out to be largely a dud of an event. The atmosphere decided to
convect early in the day in the sandhills of northern Nebraska with a
large area of elevated severe storms that moved southeast across
central Nebraska and leaving in its wake a rather large cold pool.
The best surface-based airmass was found to be over extreme
northeastern Colorado and southwestern Nebraska, but this area was
very capped. Jay Antle and I decided to target the area from Oshkosh,
NE to Julesburg, CO. In this area, towering cumulus flirted with
development into storms at times during the afternoon, but the low
level convergence was weakening due to winds responding more to the
elevated heating over the Laramie mountains. Cold frontogenesis was
occurring over central Wyoming, and storms eventually formed over the
Laramies along this front. We gave up on the capped airmass from
Oshkosh to Julesburg and drove west toward towers forming near
Cheyenne. Other storms were visible in the distant northwest through
north. Ultimately, we decided to go after a nice looking storm (both
visually and on radar) well to our northeast near Rushville, NE
entering the sandhills. It was supercellular in nature, and visually
it revealed rock-hard towers with some corkscrewing to the convection.
We blasted east on Hwy 2 from Alliance to make an intercept on this
southeastward moving storm and would be in good position by the time
we reached Hyannis. Problem though. It was moving into the cooler
airmass left behind the earlier day storms. In fact, the airmass was
so moist and not all that warm that low stratus was developing ahead
of the storm. Bad news for photography!! This was really
frustrating. Nevertheless, we continued north to intercept the storm.
It became more elongated on radar, and we were finally greeted to a
wonderful multi-tiered shelf cloud about 15 miles north of Hyannis.
We stopped for a bit to photograph the approaching shelf cloud over
the landscape of the sandhills. We then backtracked to Hyannis and
continued south on Hwy 61 stopping again to let the storm approach us.
We found a decent spot to pull off that had some adequate views
looking west amidst grazing cattle and a small pond. At sunset and on
the other side of the approaching shelf cloud, the sky lit up in
intense orange and magenta hues. The light was incredible, but I wish
it was a bit closer to us! Nevertheless, we got some good photos of
this amazing light with the shelf cloud approaching. This would be
the last of photography for this chase, but at least we managed to
photograph something out of this overall frustrating day. We headed
back to Ogallala, NE for the night.

Chase Trip Day 12 (June 27) Summary: Northeast New Mexico supercell from near Raton to near Gladstone
Summary & Images (part 1)
On the second to last day of my storm chase/photography vacation with
Jay Antle, we decided to target the area around the Raton Mesa for the
potential for supercell storms by late afternoon and early evening as
a cold front pushed south overnight and during the day down the high
plains with post-frontal moist upslope winds developing. From
Ogallala, Nebraska, we made the long drive down I-76 and I-25 down to
Raton, arriving mid-afternoon. Showers and weak storms were
developing over the mountains and we decided to monitor this
development from just south/southwest of Raton. Finally, a strong
storm did emerge southwest of Raton which visually had a
well-developed base. It was moving east-northeast toward us, but the
track of the storm appeared to be such that it would go between Hwy 64
and Hwy 56. We decided to take the northern route once the storm
approached I-25. This took us, unfortunately, out of position for
quite awhile, as the storm turned more to the right and was moving due
east if not south of due east a bit. Once we reached Capulin along
Hwy 64, we took an unpaved road south, which we could only average
about 30 mph on due to the rocky nature of the road. We were well out
in front of the storm, but as we headed south on this road, the storm
was rapidly approaching. As Jay drove, I managed to capture a few
images of the storm approaching to the west with decent supercell
structure and dense precipitation core. Once it was clear we were
south of the track of the storm, we finally were able to stop and take
some photos. The storm was on a downtrend, however, as it was getting
close to sunset. We let the storm continue on to the east as we
reached Hwy 56 finally and photographed the backside of the weakening
storm. This essentially sealed the chase day and we drove back west
on Hwy 56 back toward I-25. Before that, however, we stopped one more
time to watch and photograph the world's smallest rotating updraft.
This was rather bizarre, but it was so small, yet the updraft revealed
some barber-pole twisting structure to it. All in all, it was a
successful day in that we photographed a supercell storm, however, I
believe that we would have had a better perspective of the storm had
we dropped south early in the chase south to Hwy 56. We were
positioning ourselves for later in the chase once the storm got into a
better road network, but it just wasn't to be since the storm died
sooner than we had hoped.
