High Plains Drifter

Sunday was another out-and-back trip.  I decided on yet another spontaneous chase after pseudo monitoring the situation while doing some other things during the afternoon.  It looked like there was a convergence max in the surface wind field near Beaver, OK, and with quite good deep layer shear and adequate moisture + instability (despite it being near 100 degrees to achieve this instability), I quickly gathered my gear and set out south to Englewood, KS (again, much like yesterday!).  There were several small storms developing to my southwest, and it took awhile for a supercell to be born out of this bunch.  Once I reached ~ 5 miles south of Laverne, I headed west on Hwy 270 to intercept the base of what would become the "Booker" supercell.  After heading west 20-25 miles, I dropped south to Darrouzett, TX, and this was really when I could get a good visual on the storm’s updraft.  I noted a big mass/column of dust near the updraft area.  I saw a storm chaser, Steve Miller, on the SpotterNetwork located very near this area, so I called him to find out what was up with this huge area of concentrated dust.  This area was showing diffuse rotation, but nothing really all that tornadic.

Just before I reached Booker, TX, I saw a very focused, translucent vortex tube in the dust.  For a very brief time, there was a miniature dusty "debris cloud" looking thing right below this translucent dust tube.  Thinking that this could have been a small tornado, I pulled over and took a couple photos.  Not sure exactly what to call this, but it could certainly be argued that it was a very brief, very small tornado.  This was the only tornadic-like action I observed in the dust, although the whole time, I remained well to the east and southeast of this activity — I was more interested in the storm structure for photography purposes.  This was a well-sculpted high-based supercell with rather meaty updraft structure — including a few wall clouds.  I followed this south on Hwy 23 south of Booker.  At times I had strong easterly inflow winds around 35 mph blowing into this storm.  Around 7:30 or so, the storm was beginning to show signs of decreasing in intensity.  I wasn’t all that interested in continuing south, since I had to be back to Dodge for my next midnight shift.  I blew off the storm and headed back north through Booker and Beaver up to Meade. 

The drive on Hwy 23 in Meade County, KS was spectacular, as two storms to my northeast were on a collision course near Dodge City.  The "Golden Hour" photography light was just phenomenal — incredible contrast and color all around.  The Cb’s to the northeast were glowing orange-gold with rock-hard convection and a fantastic downstream anvil.  This was all more or less bonus material at this point, as my main goal at this point was just to get back home.  I stopped a few times to take advantage of this moment with the camera.  After the sun set, this storm finally met its demise, and I made it back to Dodge around 10:15pm or so.

This was another one of those spontaneous chases.  I wasn’t exactly planning on chasing today, but I kept the opportunity open given the decent  west-northwest mid and upper level flow pattern combined the increase in 60s dewpoints northwest toward far northwestern Oklahoma.  Since I was due in to work at midnight, I was on a "leash", so I couldn’t really stray too awfully far from Dodge City.  That said, I decided to drive down toward Englewood, leaving around 4:30 or so.  I was just hoping for an isolated storm to form somewhere near Beaver County, OK just to the south and southeast of Liberal.  I was banking on storm motion being southeasterly given the mid level winds.  No storms formed in my target area.  By dumb luck, a storm had formed well to my south around the central Texas Panhandle.  This storm, a left-moving supercell, likely split off from initial convection that developed across the TX panhandle.  The end result was a storm that was moving northeast, instead of southeast.  This was good!  It was basically moving closer to me as I decided to inch farther south and east.  I took some initial photos around the Logan, OK area of the distant storm to my south-southwest.  I drove down to Follett and continued east as the main updraft of this storm was coming more into view. 

Left-moving supercells are somewhat rare and only thrive in environments that have a nearly straight line hodograph.  Usually left moving supercells have a hard northerly component, so storm relative boundary layer winds will have a northerly component to them.  Usually air is more stable the farther north you go unless a left-split storm is isolated and within a large warm, moist sector such that northerly storm relative winds are providing inflow into the storm with ample CAPE.  Well, this happened yesterday, and this supercell was fairly long-lived for a left-moving storm.  It produced a fairly long swath of very large hail of baseball size.  Photographically, this storm was awesome.  It was all by itself against blue sky, and the convection was very crisp with fantastic contrast.  It was exactly the type of storm I look to photograph.  All sorts of color and contrast.  This was the first good supercell I’ve photographed now with my new Nikon D3 + 14-24mm f/2.8 Nikon lens.  I looove that 14mm focal length on a full frame sensor!!  No 1.5 crop factor.  Wow is it wide.  I’m going to love this on my chase trip coming up (more details on that in a blog post soon!).  I followed this highly photogenic left-moving supercell from Gage to Woodward before calling it a chase.  There were moments with this storm where a decent looking wall cloud would develop with modest cloud base rotation (anticyclonic!).  Once I got to Woodward around 8:45pm or so, the storm was beginning to shrivel up croak.  It was excellent timing since I had to start my drive back to Dodge so I could get ready for work at midnight.  Below are a few photos:

I’m not going to make this a very long post… but I’ll at least document this unfortunate chase.  Tuesday, June 10th was a day off work, and I was rather excited about the possibilities of playing with my new toy (more details in the next blog post!!) the very first day I got it.  All along, it appeared that it would be one of these marginal days for storm initiation, and if a storm went up, it would probably be all by itself, or at the very least, be some 200 miles away from the next storm.  My target for this happening was Southwest Kansas, probably not too far from Dodge City.  That isolated storm did indeed happen…. in North-Central Kansas!  Needless to say, I never made it up there, and all I could see was this tremendous back-sheared anvil way up on the northeast horizon.  This is a bust that is rather painful because I knew something like this would be extremely photogenic — tornado or not.  There were probably a handful of chasers on that storm, and only one SpotterNetwork car made it up there and that was Charles Edwards.  He actually blasted north from south of Dodge City early enough to get up there just in time before the last of the daylight.  Meanwhile, after the first Liberal storm initiated and struggled to survive — only ultimately to choke to death on the cap, I continued west in dire hope that another storm could form on the retreating dryline.   It never happened.  I ended the chase and drove back home, taking the long way… north to Garden City on US-83 then back east-southeast on 50.  I met up with Greg Stumpf and Steve Hodanish who were staying in Dodge — they also busted in the same area, so I wasn’t alone.  You win some, you lose a lot more

Here’s a StormLab screen capture from during the chase.  Note my position no where near that big red storm.  I’m at the bottom left between Garden City and Dodge City.  D’oh! 

June 2nd was the last of my 3-day mini-chase trip.  I started the day in Ogallala with Matt Crowther, Greg Brenneman, John Moore, and the "Original" Twister Sisters (Linda Kitchen and Kathy Velasquez).  Our target was west on I-80 near Sidney in anticipation of storms forming off the Laramie Range to the west.  There was a bunch of low clouds and light fog/drizzle to start the day across much of the Nebraska Panhandle, and this lingered through about midday before finally clearing off.  I parted ways with Matt’s group at Kimball, deciding to head west to the Wyoming border to monitor the first significant tower going up northeast of Cheyenne.  This first tower amounted to pretty much nothing.  I sat and waited awhile north of Pine Bluffs as weak showers/storms continued to develop around Cheyenne and points north…amounting to very little excitement.  The evening hours were waning fast and I was beginning to think this was going to be a bust.  I optioned back south closer to Pine Bluffs and continued to monitor, as I failed to give up hope.  I had a strong feeling decent storms would develop given the continued model forecast of strong convection developing in this area.

A supercell finally formed off to my southeast, and I bolted west on I-80 to a south option about 8 miles west of Pine Bluffs.  The storm showed some pretty good structure once I got far enough south.  I followed this storm east and south on unpaved county roads through the Pawnee National Grassland.  I stopped at a location east of Grover where I had a neat landscape with a few buttes in the landscape with the storm off in the distance to the north.  I managed to get a couple of cloud-to-cloud lightning images with the storm structure and the landscape with the Lightning Trigger.   I tried to get east of the main updraft area, but wasn’t having much luck.  A new severe storm was forming northwest of me, and I decided to wait for it for some more lightning images.  I photographed some long exposure structure + lightning for awhile in the southern part of the Pawnee National Grassland (north of Raymer).  I finally called it a chase at around 10pm mountain time, and headed south to Brush for the night.

Sunday, June 1st was a pretty good day for storm photography.  I targeted the far western Nebraska Panhandle, arriving at a location north of Pine Bluffs, WY by mid-afternoon.  Storms first formed off the Laramie Range and struggled for quite some time.  Finally, a cluster of severe storms formed just north of where I was positioned along Hwy 88 over far northwest Banner County, NE.  Ultimately, a supercell was spawned out of this cluster northwest of Bridgeport.  I repositioned myself to the southeast of Bridgeport after driving briefly through the core of the storm at Bridgeport, receiving 1" diameter hail.  I met up with Matt Crowther, Greg Brenneman, and the "Original Twister Sisters" at the junction of Hwy 385/92 southeast of Bridgeport.  I was greeted to a moderately rotating wall cloud to the immediate west southwest with dust being kicked up from the RFD.  We followed this supercell to the southeast across a gridded dirt road network between Hwy 26 and I-80…east of Hwy 385 (northeast of Sidney).  The storm had too much cool RFD air thanks to the high-based nature of the storm, but the structure was quite nice.  When I reached Chappell, I continued south for photography opportunities from afar.  The storm looked fantastic from the distant southwest.  I photographed the storm from the distant southwest for the rest of the chase…while pretty much all the other chasers were up close.  The isolated nature of this supercell was ideal for more distant structure shots given the pristine blue sky around the storm.  I finally called it a chase about 17 miles SSW of Julesburg and drove up to Ogallala, NE for the night.

This day was a bust pretty much.  I followed a very brief storm that developed near Boise City, OK during the early evening hours.  As soon as this storm tried to get organized it died a quick death.  The only photos I took were of the congested updraft tower looking east before the storm even showed up on radar.  This was a very ho-hum chase, and after this storm died its quick death, I drove north to Lamar, CO where I’m staying tonight.  Sunday, June 1st looks like a good chase day across northeast Colorado or the southern Nebraska Panhandle.  I have a feeling it will be a fairly north target, and the best long-lived storm(s) may be what forms off of either the Cheyenne Ridge or the Laramie Range.  We’ll see.  I need to make sure and not discount the Palmer Divide possibilities, because with large areal eastern Colorado moist upslope, it’s usually dumb to ignore Palmer Divide storms!

This will be real brief, and I will write a more detailed account on this blog post later next week.  I photographed a very brief tornado about 20 to 22 miles northwest of Jetmore at around 6:25pm from a supercell thunderstorm that initated east and northeast of Liberal…which tracked across western Gray County…and eventually through extreme eastern Finney County…clipping far northwest Hodgeman County…before moving across Ness County when I eventually said to hell with that storm and left it about 7 miles south of Ness City.  Of course, it went on to produce tornadoes once again, after there was a funky and complicated cell merger that I really did not like at the time (which was one of the reasons I abandoned it).  The other reason was I had developed "fatigue" with that storm… as it teased me for such a long time with "oh my God" rotating wall clouds and nascent 3-second funnels and whatnot.  I would have had a beautiful front-row seat to a high-contrast tornado at one point when I got up into Southwest Ness County, but it just wasn’t to be.  I got real deflated after that "false alarm".  Rather frustrating to be on a nice supercell like this and only get a brief 30 second tornado whereas other supercells all around seemed to be tornadic machines.  I really shouldn’t complain, this one image (below) is the first tornado photograph I’ve taken since October 26, 2006: 

This is a brief initial account.  Will write a more detailed account on ths post later.  I left work at 3pm and decided to chase the dryline instead of the warm front because a) storm motion would be a bit slower and b) I didn’t want to be a part of the zoo of chasers that were targetting the I-70 corridor.  I did not see a tornado yesterday, but I’m not really disappointed with the chase.  I observed a very nice but small supercell from southwest of May to Buffalo, OK to near Coldwater, KS.  I observed large hail at to different locations 1) 1.25" diameter hail about 4 miles ENE of Buffalo and 2) up to 2.5" [tennis ball size] hail 8 miles east of Coldwater.  The storm took on excellent rotation as it crossed the OK-KS border in approach toward the Coldwater area, but the overall size of the storm and dewpoints only in the 62-63F range really prevented a significant chance at a tornado.  Nevertheless, the storm cycled through numerous classic RFD occlusions, etc.  It was very photogenic toward the mid-evening hours.  

Another day another chase close to home!  These are much easier on the wallet.  My chase route on May 8th was very similar to that of May 6th — starting out northwest of Garden City and following the supercell east-southeast through northern Finney County into western Hodgeman county.  In fact, in Hodgeman county, I traveled some of the same dirt roads I did just two days prior — and had a similar "deja vu" experience of racing a storm back to Jetmore…and effectively ending the chase *in* Jetmore.

I had not planned in advance to chase May 8th, which was Thursday, in between my 1st and 2nd 9pm to 5am shifts.  Only very rarely will I be able to chase on a day where I have to be in the office by 9pm.  Typically, for this to happen, a storm has to form about an hour to an hour and a half west of Dodge City, and I basically chase it back east towards the direction of home.  I also need to find out if the office is going to need me in early in case they were short-staffed for working severe.  All the ducks were in a row for me to chase before work, so I set out for the Garden City area.  Just after I left Dodge around 2:40pm, landspout tornadoes were already occurring in the Selkirk, KS area to the southwest of Leoti.  A 1000 J/kg CAPE axis was positioned across the Garden City area to go along with very strong cyclogenesis just west southwest of Garden City.  The low level and deep layer shear was excellent for supercells.

A formidable cell finally established itself south of Leoti which was heading for southern Scott County.  I made my way to to Friend where I headed west then north on county roads for the intercept.  The storm was a dry-classic supercell by this point with a fairly nice wall cloud.  I opted to go north a bit to stay out of the sun, and viewed the updraft region from the northeast (instead of the traditional southeast).  Contrast was excellent here, and I was able to get away with this due to the lack of precipitation with the storm at that point.  Eventually, the new mesocyclone was taking shape along Hwy 83 and I had to get east… but beforehand, I optioned south to get back to the proper positioning south of the main updraft.

I reached the Finney-Scott county line road and continued east on this road for quite a distance, as the main updraft and mesocyclone rotation was about 6 miles north of me moving almost due east at the time.  Cloud base rotation was becoming a little more prominent, but rather broad.  Inbound winds on radar were approaching 70 knots (ground relative), so I knew this was a necessary ingredient for a future tornado.  You could see this inflow visually at cloud base upstream… it was impressive east to west motion.  Time at this point is about 5:10pm when I was positioned a few miles east of the Finney-Scott-Lane county tri-border.  By 5:15 to 5:20 or so, precipitation was falling in the rear-flank downdraft region, and a huge pendant echo on radar was becoming well-established.  I was running GR2Analyst and looking at higher slices, the bounded weak echo region (BWER) was incredible — one of the most prominent BWERs I have seen — and I’ve seen a lot of them.  This was just a classic supercell in all aspects. 

The RFD precip was approaching the county-line road, and it was fortunate that Hwy 23 came when it did.  I did stop a few times prior to continuing south on a couple of one-mile legs.  The first time I stopped at a T intersection with Mennonite Rd, I was observing some wild rotation in two different area to my immediate northwest and again to my more distant north.  I was preparing to see tornado-genesis at this point.  Time at this point was around 5:30 or so.  The 2nd time I stopped at a 1 mile south leg prior to reaching Hwy 23, the RFD precip was bearing down on my location as a number of chase vehicles rounded the corner to go south.  I got some decent images of the chase vehicles with the RFD precip in the background. 

I finally made it to Hwy 23 where I blasted south…but the hook echo precip beat me.  I was blasted by roughly 60mph west winds and large rain drops on the way to my next east option, which was Lake Rd. through Ravanna (which isn’t a town, all Ravanna is is ruins of one building).  I had to keep blasting east to get a decent view of the new mesocyclone area.  All this while, I was probably thinking there was a rain-wrapped tornado way back in the old occlusion.  I never saw any evidence of such, though.  At one point though, I did see what looked like a large old "tornado cyclone" cloud mass reaching the surface.  That was interesting!  It faded quickly though, and I only got photos of the break-up of this feature.  As I made it into western Hodgeman county, the storm was transitioning fairly quickly into an HP storm as it was making its bead on Jetmore.  I traveled east on a farm road a couple miles north of Hwy 156 on my way to Jetmore.  The structure was quite good, despite the storm being very wet now just to my north.  I eventually made it to Hwy 156 and then to Jetmore before the large hail hit…and I continued south on my way home.  I ran into my co-worker, Scott, who was out chasing with his son south of Jetmore as we watched the now HP supercell travel east away from us.  New storms were forming to the northwest, and I managed to get a few images of this before finally calling it a chase.  When I finally called it a chase shortly after 7:30pm, I was only about 10 miles from home — still having almost an hour time to spare before going into work!  A very nice "spontaneous" chase to say the least!

My chase target on Tuesday, May 6th was west-central Kansas somewhere with a starting point of Scott City in mind.  I set off for Scott City around midday, reaching the Scott City area around 2:30pm.  There were already storms developing between Lamar and Holly where convective temperature was being reached in the 83-85F range.  A cluster of small storms had eventually evolved as they moved into the Syracuse, KS area.  This activity was moving into 2500-3000 J/kg surface-based CAPE environment with dewpoints around 58-59F or so.  I expected an organized severe storm to form out of this stuff.

After monitoring things for a while just outside of Scott City, I drove south to intercept the primary strong updraft north of Highway 50 between Syracuse and Lakin.  I eventually reached a stopping point about 5 miles north of Holcomb where I got a pretty good view of the high-based updraft at around 4:00pm.  The storm rapidly strengthened by this time and took on supercell characteristics.  Inflow was excellent into the storm with south-southeast winds around 25-30 mph.  A high-based wall cloud showed periods of interesting rotation to my northwest, and as long as the rear flank downdraft wasn’t cold enough, tornadogenesis would be possible.  Of course, that wasn’t to be.  Around 4:15pm, I started to get nailed by cooler west winds denoting the more stable rear-flank downdraft.  Once I felt this, I knew tornado prospects were done.  I drove east a few miles before noticing a number of dusty spin-ups (RFD gustnadoes) at the inflow-rear flank downdraft interface.   I was fairly close to a couple of them and got a few photos.  It was time to keep heading east and focus on the structure of the storm.

Around 5:00pm, the storm developed another classic RFD clear-slot, albeit still high-based.  Around this time, looking to the north-northwest, the rotation in the wall cloud was probably about as good as it ever got with this storm, and a nascent funnel (albeit quite brief!) developed beneath this rotation.  This feature quickly fell apart, and I continued east along Hwy 156.  By 5:30, several other storms were developing immediately northeast of the initial supercell…all spewing out cold outflow as well…so it wasn’t long before this whole system was severely outflow dominant.  Around 5:45, I manged to stay far enough east to get one decent set of images of the original supercell updraft with a long high-based shelf cloud extending northeast.  I wallowed about western Hodgeman county through 7pm photographing the storms along and north of Hwy 156.  Another strong updraft surge developed northwest of Jetmore around 7pm or so which revealed interesting structure, of course about 10-12 miles north of the outflow boundary.

I drove back to Dodge, but instead of heading home, I continued west to Cimarron then north a few miles to photograph some lightning at the west end of this complex.  Not much success with the lightning, but managed to get a couple images.  I was back home by 9:15pm or so.
