2012 Summer Wildlife

I have been photographing wildlife near my parents house most of the summer when I have had downtime from chasing and moving.  Enjoy some images below of critters in their natural habitat.

Turtle Trio!  But...can you find five painted turtles?

6/8 - 6/12 2012 Check Yo' Mileage


Mid June provided a lot of driving with few opportunities for classic supercells.  Alas, Walker and I trekked to the northern and central High Plains for storm photography chances, as chasing opportunities were dwindling for both of us (I have one more trip coming up in mid-July).  It is nice to take personal chasing trips, as logistics of tour-guided chases be stressful (e.g., lodging for 18 folks, forecasting pressure, bathroom stops, food).  Personal trips often provide unique opportunities to become close with Ma' Nature, especially when your daily average mileage for the trip nears 800 mi.!   Along the way, we were able to take in some beautiful landscapes including:  Teddy Roosevelt National Park, Pikes Peak, Great Sand Dunes National Park, Sangre de Cristo Mountains, Collegiate Peaks, and Capulin Volcano National Monument (second trip there for me in less than a month!). 

I love guiding people into the Plains, but it sure is nice to have a personal trip once in awhile...

5/25/2012 LaCrosse, KS HaboobNado

Friday contained feelings of disappointment and amazement.  Highlights included a few brief dusty tornadoes just northeast of LaCrosse, KS, including a large dusty haboob-like rear flank occlusion.  The local environment was primed for tornadic supercells, characterized by a northward lifting warm front with backed easterly flow, adequate deep-layer wind shear, plenty 'o moisture, and steep lapse rates contributing to modest instability.  The small limiting factor were the dewpoint depressions, contributing to less than ideal LCLs/LFCs.  Thus, parcels were not "convecting" in the lowest portion of the atmosphere and taking advantage of the excellent low-level directional shear.  As the boundary layer began to cool around sunset, supercells near LaCrosse and Hays began became more tornadic with a 46 minute tornado occurring near LaCrosse.  Unfortunately for us, we stuck with the first storm and just could not understand why it could not get its act together despite the favorable ingredients in place.  We followed this storm east of Hays and new convection began to fire further to the southwest on the now stalled warm front.  We gave it a look initially on radar but figured it was best to just stay put and try to take lightning photos as the sun began to set.  Stupidly, I sat out of the car for about 30 minutes enjoying the sky and taking photos and was not watching radar. Hence, I failed to navigate us to the LaCrosse storm as it began to produce a tornadofest.  I was angry with myself at first, but I realized that it is impossible to see every tornado even if one makes a good forecast (our morning target was LaCrosse and we sat there all afternoon; shoot!).  While I had a bad taste in my mouth most of the night, Craig and Tony were absolutely fascinated with the initial supercell to the northeast of LaCrosse.  Honestly, it was great to see them so excited.  Sometimes experience can immune one to the real joy and excitement that is being on the Great Plains observing convection.  The UGA guys reluctantly head back tomorrow, but it has been great having them as company.  As for me, I will give it one more shot in KS/NE tomorrow before heading home for Memorial Day.

5/24/2012 Wilson Lake State Park

Tony, Craig (UGA graduate students), and I decided to call off Thursday's chasing possibilities in southeast KS due to a strong cap and instead ventured to Wilson Lake State Park in north central KS to camp.  It was a very picturesque location (especially for KS!) and provided a perfect location to set up for our Friday chasing opportunities near Hays, KS.  We enjoyed a fire and a few beverages before calling it an evening.

5/23/2012 COnvection

We targeted a marginal setup for supercells in eastern CO on Wednesday with limited moisture in an upslope regime.  One of the supercells sported some nice structure and treated us with a pretty sky just before dusk.  We stayed in Colby, KS on Wednesday night and made it to our hotel before getting a nice hailstorm.  Check back for a timelapse of this setting in the near future...

5/19/2012 Kingman/Harper, KS Tornadoes

We did it!  CoD Trip 2 had everything on the line Saturday after a quiet week in the severe weather world.  We had been watching Saturday's setup for a few days and knew it would be our only hope to bag a tube before heading back to IL.  We awoke at a nice Fairfield Inn in Hays, KS (first time staying there actually; however, I've stayed in Hays numerous other times) with maps printed and ready to analyze.  John Monteverdi (SFSU professor) chatted with us in the morning and was excited to see our students performing hand analysis of the morning observational data.  You could sense the excitement amongst the students, even though it was admittedly not one of the best tornado setups.  Optimistic would probably be the best way to describe our feeling about the day because we were sure there would be storms due to the forcing for ascent, but moisture was limited and upper-level wind vectors were aligned parallel to the surface initiating boundary.  Given these caveats, we were worried that storms in central KS would interact with one another and congeal into an MCS rather quickly.  In days leading up to Saturday, we talked about targeting the Woodward, OK area due to better shear vector orientations relative to the dryline.  However, we noticed this area beginning to fold over and surge southeast due to a building surface ridge on the lee side of the Rockies related to subsidence behind the advancing vorticity maximum. The boundary instead sagged in more of an east/west fashion leading to similar problems of what we were expecting to happen in central KS.  Instead of heading to western OK for the later show due to a stronger cap, we instead hung out most of the afternoon in Pratt, KS watching visible satellite.  It was decided that a better chase strategy would be to play the tail end of bubbling cumulus just west of our location.  These storms quickly became prolific hail producers, but it was apparent that the strength of the forcing and cap were leading to a non-supercellular convective mode.  What happened next was amazing...  We started noticing several high-based [LCLs were near 3 km] funnels just west of Kingman, KS.  A couple of these funnels eventually turned into tornadoes, but they were not associated with mesocyclones.  Instead, I'm assuming that preexisting vorticity near the surface boundary was being stretched by the rapid vertical acceleration near the surface due to the nearly dry adiabatic lapse rates.  Numerous tornadoes were being reported west of Kingman by late afternoon.  We kept dropping south/east with the storm motions and witnessed a long-lived tornado near Harper, KS.  Looking at radar, this tornado appeared to be more of a hybrid with a clear inflow notch and a supercell-like hook echo appendage.  Either way, this tornado was very pretty and the students were fascinated.  The group on this trip was one of the best I've ever had and it was great to get to know them / learn about their lives.  Ten days that I will not soon forget...

Getting creative with the CoD Van.  Kudos to Amy for thinking of this! 
 After creating the legs of the Wicked Witch, we found the TIV and decided to make a funny photo opportunity.  It was quite a hit with the ROTATE folk.

5/17-5/18 2012 Hangin' in CO

Thursday and Friday were also "down" days for severe weather as a pesky low pressure system across the Gulf Coast created offshore flow.  So, we decided to head to the front range to enjoy the scenic view of the Rocky Mountains.  We ate great food and enjoyed some beverages after visiting the Garden of the Gods and catching a Colorado Rockies game on Thursday.  We had a great time in the center field bleachers! We stayed in Denver Thursday night and ventured to Bloomfield, CO on Friday morning to visit the Aviation Research Facility branch of the National Center for Atmospheric Research (NCAR).  This was cool as I have never visited before.  Mike Daniels was gracious enough to let us tour the facility and the aircraft hangar.  All students were able to climb up into the research C-130 cockpit and view all of the instrumentation.  Very cool! We overnighted in Hays, KS to position for expected severe storms on [Saturday] what appeared to be the best setup for severe weather of our ten day trip.
