Close But No Cigar

Yesterday added a tenth new state to the list for me: Wyoming!  We hung around Sterling, CO for most of the morning and then in early afternoon, finally decided on a northern target and took off for the Wyoming/Nebraska panhandle border.  While en route, we were alerted to a violent tornado near Chugwater, WY but unfortunately we were just too far away to  make any sort of play on it.  There was a brief point where we thought we could make it out off in the distance, but we can't be completely sure because there were a lot of hills and a pretty intense precipitation curtain.  This tornado ended up destroying five homes, derailing a train and injuring one.  Crazy.

We did make it to a beautiful supercell that looked promising for quite a long time.  It had an incredible structure and lowering wall cloud.  We saw a huge funnel and according to the DOW radar data, it briefly touched down on the road behind us; however there wasn't a condensation funnel visible all the way down.  It was by far our most organized chase yet so we all felt a little victorious last night.  We stayed in Ogallala, NE (try saying that five times fast) and this morning, we are racing north to near Rapid City, SD where the models are looking really, really good!

I think pictures are probably the best way to describe the chase yesterday...

Chasing Close to Home

Well as the title of this post implies, we are chasing in eastern Colorado today, just as we did yesterday.  It's a weird meteorological setup which involves this phenomenon known as the Denver Cyclone.  It involves upslope flow and doesn't require quite the same level of atmospheric ingredients for severe weather that we are typically inclined towards.  Yesterday we didn't quite play aggressively enough and missed out on some big hailers and even a few tornadoes.  Even though our target city wasn't quite in the right sweet spot, the storms were nearly stationary for hours and we could have made a play.  Instead, we ended up at a Super dee Duper Motel 8 in Sterling, CO that smells like cow manure and has a lovely view of the penitentiary.  Today we are considering two plays, one North and one South.  The northern play is in the Nebraska panhandle (better moisture, not much instability and a pretty decent punch from a shortwave.  The southern play is southeast of Denver where all the CAPE is found.  It's one of those days where we just have to flip a coin and have no regrets about where we choose to target.  I was fortunate enough to have a long forecast discussion with Tim Marshall (an icon in the storm chasing world) this morning.  He's feeling the southern play...so we'll see!

Update on the new Scout 1 driver:  Marcus is awesome!  He's another TIV driver, in addition to being a surgical PA, owning a film company and clothing line, producing music videos, avid surfer...  It's unreal the people you meet while storm chasing.  I'm glad he is joining our team for the next couple of weeks!

One final note for this morning, I'm attaching some pictures from a beautiful hike we did on one our down days in El Dorado Springs State Park in Colorado.

Those three pesky, little words...

Back to Boulder. Yup, it's true.  We've been back here already for a few days; and well no promising weather on the horizon either.  There is a little glimpse of hope in the form of a shortwave through Montana and Wyoming by Wednesday but I'm not holding my breath just yet.  I say this every time... Boulder is a beautiful city with lots of fun things to do.  But if I wanted a Colorado vacation, I would have just taken it.  I want to be storm chasing!  But nonetheless, contrary to what many people think (drunk college students), meteorologists cannot actually control the weather.  So why not make the most out of a bad situation and enjoy the beauty of the Rocky Mountains.  The first "down day" in Boulder, however, I spent sick in an urgent care clinic and then my hotel bed.  According to the doctor, I was severely dehydrated and had a nasty sinus infection.  Antibiotics and coconut water to the rescue!

By our second down day, I was feeling a bit better.  So I took advantage of the morning "heat" (yeah, right...obviously these people have never spent a summer in Tallahassee) and went for a jog around Boulder.  Then in the afternoon, a bunch of us went up into the foothills to do some hiking and fishing.  The trail was at about 7280 feet and it was a pretty strenuous/technical trail; you know the kind, part hiking/part rock climbing!  But the trail ended up at this remote little beach where a creek with rapids slowed and emptied into the inlet of the Gross Reservoir.  It was absolutely stunning.  It felt so isolated and untouched. There was a little beach and some beautiful storm clouds lifting over the mountains in the distance.  Spectacular.

Today, unfortunately, was a work day so back to the hangar!  Scout 1 and 2 were given a special mission to check the validity of our wind measurements from the Russell, KS tornado.  Our task was basically to drive up and down I-25 a bunch of times, side by side, taking measurements with our anemometers.  Needless to say, we pissed off a few drivers taking up the only 2 lanes for many miles.  I felt like we needed a sticker on the back of the Scouts saying "For the sake of science, don't tailgate!"  When we got back to the hangar, we were greeted by a beautiful storm.  The way the topography up here morphs the cloud bases is unlike anything I have ever seen.  It gives the sky this random, paintbrush texture.  Can you tell I'm in love with the mountains, or what?

The Science Speaks

So today we had our official May 25th tornado track update from Josh and Karen.  They analyzed radar data, lat/lon coordinates, Scout 1 mesonet data, the house damage and more to establish the "real story" of last Friday night.  We all had our own versions; how we saw that night in our minds as we remembered it.  As with any eyewitness testimonies, we all had certain aspects of the event that were truth and some that may have seemed differently than they really were that night.  Adrenaline and shock play a huge role in the way we recall traumatic experience.  I am proud to say that my memory actually passed this test fairly well.  So here's the scientific story...

Scout 1 got hit twice by the tornado believe it or not.  In my post I mentioned two periods of really high winds that our vehicle took on.  The first go around, we received 70mph winds from the developing tornado on the strong southern edge.  The tornado then dissipated a bit, jogged back west, and we moved up the road farther North.  When we were about 230m from DOW8, at the intersection where the house was, the tornado redeveloped and headed due east...right at us.  We received a direct hit with cross winds out of the west at around 100mph.  The tornado then headed up the road due north before jogging east one more time at the intersection.  DOW8 received winds from the weak side of the tornado, but at its peak intensity.  Pretty crazy stuff.

Once again, I am updating from the car fighting very spotty internet connection so unfortunately this post won't have any more pictures.  I'll try to add some tonight since we will be staying in Amarillo (a big city with wifi!)  Two days ago we chased in Texas and got caught in some gnarly outflow.  There were 40mph winds and blowing dust that limited visibility to zero in some places.  The sky was that green color you always hear about on television and movies.  There was some fairly large hail too.  In fact, the last couple of days we might as well have been hail chasing rather than tornado chasing.  Yesterday, Ronan left to go on to his next job.  I had a bit of a sad day because he was the one person I felt the closest to on this trip (a big part of that being the experience we had Friday night).  But the chase goes on.  Yesterday we were in Oklahoma, which is quickly becoming my least favorite state to chase in.  We had the most beautiful and "perfect/textbook" supercell yet but the cell phone and therefore internet coverage is really spotty and there is always this major chaser convergence!  It is impossible to drive anywhere because of the chaser traffic.  But we did get to see a brief rain & hail wrapped tornado.  Unfortunately we couldn't deploy because we were a bit too far away but it was still pretty awesome!  Then on our drive home, the supercells morphed into an MCS bow and we got caught in some large hail.  There were a few tennis balls falling.  Somehow we escaped without any damage to our instruments or vehicles.  The driving was rough though because we were on the interstate and there were major traffic jams as people tried to stop under the overpasses.  So dangerous.

Today, something went majorly wrong in the models and storms initiated well southwest of where most people forecasted, including the Storm Predicton Center.  The next few days look bleak as well, soooo....I'm cringing as I write this....back to Boulder??

Update on Pat

So our team found out today that Pat will be okay.  She has a broken collar bone and no memory of that night but she will live.  We also found out that happened to her home.  It didn't break apart right away as it looked to us.  Instead, it was picked up by the tornado and dropped 50 feet away from the foundation.  It then collapsed around her.  It is an absolute miracle that she survived.

Humbling Night

Well as anyone on Facebook probably saw, last night was absolutely the single most terrifying and humbling night of my life.  Josh has confirmed that the vehicle I was in, Scout 1, received a direct hit by the outer circulation of the strong side of an EF2 tornado.  We were chasing in central Kansas surrounded by three supercells with tornado-producing wall clouds.  It was like rolling a dice decided which one to go after.  From any one vantage point we could usually see at least two of the wall clouds; and the velocity signatures on radar were blowing up.  We let the first warned cell go by, but the second one we almost immediately had a visual on a rope-like tornado near Walker, KS.  http://www.youtube.com/watch?v=BwOUnkb5iQg&feature=youtu.be  It was very close to us; in fact the upper circulation was directly over our heads so it was a race to get ahead of it in order to deploy pods.  But before we could, the casing for our temperature/relative humidity sensor on the mesonet fell off and another vehicle, M2, ran it over!  Josh jumped out of DOW7 and came into our Scout and directed us along a road until, unfortunately the tornado dissipated.

But like I said, we were seeing tons of rotation all around us, so even though it was getting dark we got ourselves positioned for the next rotating updraft.  DOW8 was sent north along the road to get a good scan of the developing tornado while Scout 1 followed closely behind, by about a 1/4-1/3 mile.  By this time, it was pitch black except for the lightning and we knew we had a tornado on the ground but communication  fell through and we couldn't get any azimuth or lat/lon of the circulation from the DOWs.  So we are sitting on this road trying to watch for the tornado in the lightning and then we look up and see TIV (tornado intercept vehicle) and Sean Casey maybe a few yards in front of us between us and DOW8.  We got struck by a big gust and the truck rocked a bit but then it got very quiet and still. So Josh told Karen the tornado had crossed the road in front of us but she kept yelling back into the mic "NO NO NO It has not crossed the road yet, 0.5km away from your position!"  Next thing I know, my ears erupted.  It was so painful to feel that pressure change and my heart dropped into my stomach because I knew what that sudden change must have meant.  And then the wind came out of nowhere and shoved us.  We could see the circulation on the ground in our headlights and our truck started turning to the side.  Ronan, being the a very skilled driver (drove TIV and a production vehicle for ice road truckers) put the car in reverse and steered our back into the strongest wind so we didn't skid any further.  But when it was over, we had been spun a bit and he had reversed more than 90 degrees.  Our mesonet only read 100mph but I believe it was a bit higher than that.  We then looked up and saw a house beyond DOW8 explode.  Completely explode.  Debris was everywhere and you could see the condensation funnel on the ground in our headlights.  We jumped out as soon as it stopped and I started to run up the road to take pictures, but then realized there was debris falling from the sky all around me. So I ran back to Scout1 and did my best to hover under the side view mirror.  We heard yelling on the radio that DOW8 had been hit as well and had a broken window!  But once we had confirmation that they were okay, we drove up towards the house and discovered there was literally nothing left, not one wall was standing.  We later found out it was a modular home that had no been strapped to the foundation.  It had been picked up by the tornado and tossed more than 50feet, where it tumbled back to the Earth and shattered.

It was as though someone had hit the slow motion button on a remote up until that point; and then suddenly we were thrust into fast forward and what really took over an hour, seemed like seconds.  I yelled to Josh that I saw a car in the driveway and someone might be home; so I grabbed my phone to call 911 and Ronan and Josh ran towards the debris calling out for anyone.  Before I could finish dialing I heard yelling from the neighbor across the street.  I ran over to her and she told me her elderly neighbor Pat was on the porch right before it struck.  I rushed across the street to relay this to Ronan and Josh.  Ronan was the first to hear moaning and was able to pick his way through the rubble towards the woman, who by some miracle was laying on top of the pile, barely buried with a few bad gashes but awake and somewhat responsive.  By then, a couple of sherrif's deputies pulled up and asked me if I lived here.  I said no but told them someone was injured in the house and where she was.  They asked me to find a flashlight so I ran back across the street to the hysterical neighbor and managed to calm her down enough to find me a flashlight from her home.  She kept screaming asking me over and over if her neighbor was alive.  I told her she was and that the best way to help would be to calm down and to find a flashlight for the paramedics.  I could hear her children frightened in the basement.  She got me a flashlight and I ran back across the street, remembering just feet from downed power lines to watch where I was going closely.  There was glass and nails and wood everywhere as far as you looked.  By this time our team paramedic was with the woman and a local firefighter.  I picked my way through the debris, cutting and scratching my legs a bit, and held my phone and flashlight over the firefighter's shoulder who was holding the woman's neck steady.  Our medic Eddie was asking the woman all kinds of questions, her name, age, who was president, what year it was, her address, did she know what happened... She knew her address and other than that could only tell us tornado over and over again.  She was definitely in shock.  To make matters worse, it started pouring.  I took off my jacket to hold over the poor lady who was covered in blood, insulation and drywall dust.  Ronan gave me his jacket but I was soaked from head to toe by this point anyway.  Once the ambulance arrived, I was sent by the paramedics to get blankets from the ambulance to keep the woman dry and I once again picked my way through debris.

Once she was in the ambulance and we got back to our vehicle, that's when it all hit me.  I felt extremely overwhelmed.  Tornadoes, to me, are the most beautiful things on the planet.  But in that second where I was standing over this woman in the pouring rain holding a small pinpoint flashlight, smelling natural gas, shaking from the cold and rain, I looked down and realized that I was standing on a small Christmas trinket tin from Pat's house...I hated tornadoes.  We kept chasing immediately after the rescue, like nothing had happened.  But I was completely humbled.  I still don't even have a grasp on all the emotions that went through me last night.  I stayed up until nearly 5am talking to Ronan and Herb, one of the DOW engineers, about the stress and shock of a situation like that.  You see damage photos on the news but you can't (I never did) possibly understand the human emotion of being caught in something like that.  It's completely indescribable.  Today we are chasing in northeast Nebraska and tomorrow, our target city is none other than Russell, Kansas again.  I have mixed feelings about this because I don't want these poor people to be put through this again so soon but I want to possibly go back to the lady's house and talk with her neighbors, maybe bring her flowers.

***We found out later that Pat was stabilized at Russell Medical Center and then transported to Hays Hospital where they discovered several broken bones, including her back, neck, clavicle, and chest plate.
