April 14 - Tornado Outbreak

April 14, 2012 was a historic day for stormchasing. This was the last day of the 4-day chasing trip with Verne and Eric Carlson and I. It was the first day I finally got to see a tornado, and will likely be my best chase day for a long time.

Everyone knew this was going to be a big day. The National Weather Service Storm Prediction Center gave it a high risk rating the day before, which they said "is only the second time a high risk has been issued for the day two forecast, and the first time ever it has been issued for the initial D2 outlook." High risks are usually issued the day of, and they are extremely rare. I've only chased slight risks and maybe one or two moderates that got downgraded to slight.

The morning of the chase, the data said the probability for tornadoes in the high risk area was 45% hatched, meaning at any random point on the map there would almost be a 50/50 chance of having a twister within 25 miles at some point in the day. That's extremely high.

The blue is our path through the day
We started off the day heading up to Smith Center from Russell. The cells were a bit messy, just lots of rain and lighting. At one point we heard a nearby town testing their tornado sirens.
Next we moved east to Beloit in hopes of glimpsing a twister that had been reported on a cell moving that way. Visibility was low with a lot of heavy rain. Following behind two other cars to where the storm would meet us, the other two suddenly pulled over. The Carlson's wondered what they knew that we didn't, when suddenly we got a radar update that looked as though the area of rotation had made a sharp turn straight for us! We back up and paced around a bit and studied the rain to figure out where a twister could be in it. At one point the rain cleared enough to see what supposedly was a tornado. So technically this could be my first tornado, but I wouldn't have recognized it as such and didn't see it long enough to distinguish any rotation.

Back in Beloit, the flooding was incredible. Because of all the washed out roads we had to turn around several times while trying to make our way south, and eventually went back into town only to find cops staring to barricade the main roads!

Finally we escaped and dove down to a new cell near Lyons. It started out as two separate promising storms, but they merged into one. We waited awhile to see if it could recover from the merge. Verne decided to give it one more chance before we would look for another storm, so we turned North to get closer to it. Just over the hill, a tornado came into view. Of course I thought they were pointing at the little satellite on the left, and that big wide thing was just a wall cloud. As we got closer I saw the 'wall cloud' seemed to be touching the ground. And rotating. Now THAT is a tornado.

A monster tornado comes into view
Though I have been stormchasing 10 other times now, the 'chase' part really didn't make much sense until the moment a real tornado came into view. Most of what I've done previously would be more like storm watching and storm following. NOW there was actually something to chase. Tornadoes can move very fast, and this one was definitely moving away from us. Trusting Verne's 30 years of chasing experience, he got us where we needed to be!

That's us, on a mission

At one point we turned around from downed power lines, and eventually got stopped again by trees blocking the road that the twister had just torn up. That was just about the end of our time with this tornado. After that we had some navigation issues on bad dirt roads and fell too far behind. The tornado went a little farther and lifted right at the north edge of Salina. They really dodged a bullet, a lot of chasers compared this tornado to Tuscaloosa and it would have caused the similar damage had it hit town.

Destruction, the Carlson chasers, and the EF4 tornado
The most impressive damage we saw from it was crossing a bridge and riverbed. There was a brown dirt trail it had left through a field, and incredible tree damage and churned earth over the dry river. That's what it was hitting when I took that panoramic photo above, and right where it is in the popular Twistex Sameras video.

One good thing about seeing a tornado this intense is that it didn't cause any injuries. There were plenty of snapped power poles and one house that had some roof and front porch damage. The NWS rated it an EF4 (the scale is 0-5).

Me with the tornado. Yes, it was exciting.
We jumped on the interstate and caught up to the storm again northeast of Salina, just north of Solomon. The traffic jam from stormchasers and gawking locals was incredible. Eventually we somehow got way ahead of the crowd, and were one of the very few cars that got to stop and enjoy the amazing rope-out stage of this tornado.

Everyone earned a steak dinner after this day. We met up with Michael Carlson and Eric Haave at Logans Roadhouse and swapped stories and photos before heading back to Russell for the night.

Now the best for last: Here's Eric's video from the day!



4 days, 2,883 miles.
Big thanks to Verne Carlson for bringing Eric and I on this journey!

Storm Chase-cation

Eric's dad invited us on an epic stormchasing trip at the end of last week. Zig zagging across tornado alley, from Colorado we visited both Texas and Nebraska once, and crossed through Oklahoma and Kansas three times each. Over 4 days, Verne and Eric Carlson and I went a total of 2,883 miles.

We left early afternoon and raced down to La Junta and the Comanche Grasslands. The storms ended up not doing a lot, and there was an incredible haze that really limited visibility. On our way to Amarillo for the night, the road was closed from Dumas on because of large hail drifts. Took the long way around and stopped to watch lightning illuminate another developing storm heading back into Dumas.

The target moved up to Goodland, KS. We went up the road to Dumas to see the hail drifts, and later in Cactus we saw some major flooding.

Waiting in Goodland along I-70, nothing seemed to be developing where everyone was expecting. Eventually some cells did fire up north at the Nebraska border. We raced up there and found a good vantage point just south of Trenton NE. A small funnel cloud developed, but that was the most we got.

We got gas in Atwood KS and ran into the Dominator from the "Storm Chasers" TV show. I was excited to finally see it. Verne and Eric however were much less impressed and just stopped to catch up with Reed Timmer (who was totally zoned from both chasing and working on his phd).

Driving south to our target of Enid OK, I got to hear many fascinating stories of all the tornadoes Verne has seen driving on the exact roads we were traveling.
We made time to stop in Wakita, Oklahoma to see the 'Twister' museum. This was the main town that got hit by a tornado in the movie.

The only storm that produced a tornado that day went over Norman, on the southeast side of Oklahoma City. We didn't want to deal with traffic close to the city so opted to stay on the outskirts, and watched a cell over Chickasha instead. It went outflow dominant, but someone said they saw Verne's live web stream airing on CNN while we were watching it.

West of Oklahoma City

On the drive back to Russell, there were spinouts every mile from all the rain. Earlier we had even seen a kid hydroplane off the road right in front of us.
The last day of our trip by far had the best storm outlook, but that day deserves its own page. Next post: April 14, 2012 tornado outbreak.

March Stormchasing - Texas

Verne Carlson, Eric Carlson, and I headed down to Amarillo for a promising weather setup for March 18, 2012.
Cadillac Ranch
Having gotten in position a day early, we spent the morning geocaching and visited the Cadillac Ranch. Later we headed out to Childress to watch the storms build. Several other chasers they knew pulled over on the same road and we all chatted for just a few minutes. I thought it was interesting how everyone snuck away without saying a word. No one wants to give away where they're going next!

Watching the Supercell
We abandoned the Childress cell moving north, and instead headed down to a storm on the southwest side of Crowell. There was a huge line of chasers on this one, and even Roger Hill's tour group was nearby. We went off the main road to get closer, and watched an incredible display of funnel clouds forming. Each one got so close to turning into a tornado, but never did. Nonetheless, it was the clearest funnel clouds I've ever seen and we had a fantastic view.

We followed it a little ways north and eventually just went back to Amarillo. The next day's target moved too far east. On the way home we made a quick photo stop at an abandoned motel in New Mexico.
