April 17, 2013 chase near Duncan, OK

After several hours of watching development through the day, I finally hit the road about 1:30 pm.  The target area I’d chosen at 2:20 am was still my preferred target for the chase.  That meant that I was 3 1/2 hours away from where I needed to be.

I’d hoped the a potential target area would have moved closer to Tulsa.  I was wrong.

I jumped on I-44 and headed towards OKC.  My plan was to dip south before I hit the OKC area.  Ooops.  That was a mistake I won’t make again.  It took me an hour to get south of the city.

The storms were developing west of Lawton, moving to the NE.  Fortunately for me they were only moving about 25 mph.  I still had time.

I turned to the west on highway 9, south of Norman and then south on I-44.

I stopped at a truck stop to use the facilities and refresh the liquids.  I also took some time to review the radar again.  A man came up to my window and asked me how it looked.  He was heading to Lawton.  I shared the radar with him and we both agreed we’d try to make it to Chickasha.

The target was now Chickasha, northeast of Lawton.  I thought I’d be in perfect position if the storms drifted to the north a little.  Again, I missed the mark.

The  storms were traveling NE, right up I-44, and right for Chickasha.  They were intensifying and quickly became tornado warned.  I realized I was in the direct path and needed to get south.  Quickly.

South towards Duncan was my only escape.

A few miles north of Duncan, I turned around and pulled over.  The view to the west didn’t look all that bad.

The radar told me something different.  The storms were powerful and still building.

In this enlarged image, you can see my location (green triangle).

20130417-TWXC-03

I sat in the drive of a communications tower.  Another smart move.  I kept studying the radar and the sky.  The conditions were worsening.

20130417-TWXC-05

20130417-TWXC-06

Some lowering was occurring, but I wasn’t concerned.  Yet.

20130417-TWXC-04

Something nagged at me.  Sitting next to a tower with this storm moving in might not be the best plan.  I needed to move.

As the storm moved to the east, I inched my way back north.  Viewing the storm from the proper position.  Reports were coming out that a tornado had touched down near Lawton  and Chickasha was in the path.

I stopped again to review the radar.  It was 6:35 pm.  The storms were moving in.  The sky was darkening, the tornado warning had moved to the east and I was in perfect position.

20130417-TWXC-09

To give you an idea how stupid some drivers can be, a man stopped next to me and rolled down the passenger side window.  He said, “What’s going on?”  I guess he noticed all of the cars pulled over to the side of the road.  ”That.”, pointing to the storm ahead of us.

20130417-TWXC-11

“Oh.  Cool.” was his response and he sat there looking at the sky.

I looked in my rear-view and saw traffic heading towards the north at highway speed.  Mr. Brilliant was still sitting in the right-hand lane.

“Um, sir?”

“Yeah?”

Gesturing for him to look behind him, “You might want to get off the highway.”

“Huh?”

“Get off the highway, NOW!”

I guess he got my subtle hint and pulled off to the side of the road in front of me.

20130417-TWXC-12

I stepped out of the truck and got blasted with the downdraft.  That was pretty awesome.

The storm was now moving across the highway.  Still heading for Chickasha.

20130417-TWXC-17

20130417-TWXC-19

There was still some rotation, but the storm had been downgraded from a tornado warning to a severe thunderstorm warning.  It was dumping hail and a large amount of rain.  Flood warnings were being issued.

Not wanting to get into hail, I stayed south of the storm and studied the structure some more.

20130417-TWXC-20

Once I was sure I would miss the worse of it, I drove back towards Chickasha.  I didn’t hit any hail, but heavy rain was falling.

I stopped in Chickasha for a little bit and grabbed a snack.  I should have gotten gas too!  I will come to regret this decision.

At 8:00 I left Chickasha for Tulsa.  So much rain had fallen, the main roads were flooded.  I was on 4th street and slowed down to a crawl to get around stalled vehicles.  Flood water was up to the bottom on the doors.

Eventually I was able to get back onto I-44.  I was out of the high water, but a few drivers weren’t so lucky.  Some of them were in the ditches.  Driving rain and hydroplaning don’t mix well.

I still need gas.

North and WEST of OKC, I found a place to gas up.  I now wished I’d done that earlier.  I was getting tired and still had a two hour drive ahead of me.  Heavy rain would accompany me most of the way.

About 30 minutes outside of Tulsa, a new tornado warning was issued.  That storm was right behind me.  I stepped on the gas.

I pulled into the driveway at 11:30.  After a 10 hour, 410 mile run, I was finally home.

Fortunately the rain was light.  I began unloading the gear into the garage.  I had about half of the gear disconnected and unloaded when the tornado sirens in my neighborhood sounded.  The storm that had been chasing me, had made it to Tulsa.

Yes, I quickly finished unloading the truck.  Heavy rains fell, thunder roared and the wind blew HARD.  It was a major storm.  The scanner chatter indicated that we had rotation just a few blocks form my house!

This is what I was looking at on radar.

20130417-2354-rad

The storm had already done damage and would go on to do more damage in Bixby, Broken Arrow and Inola.

I quit watching the radar shortly after 1 am.  This day was not going to end.  Finally, just before 2 am, it was safe enough to go to bed.

My chase day was finally over.

Damage reports on Thursday would reveal that what had come through the Tulsa area was an EF1 tornado.

 

Preparing for the chase: April 17, 2013

2:20 am

The chase day begins early here.

I’ve just taken another look at the models for a chase today. With what I’m seeing right now, the target area is around Lindsay, OK, about 3 hours southwest of Tulsa. I’m hoping I won’t have to go that far south.

20130417-0234-target

I’m still not real impressed with the setup, but I’ve not been impressed before and ended up having a good run.

I’ll look at the next set of models in about 3 hours or so.

6:17 am

I’ve looked at the latest data and, at this point, I’m sticking with my target area. I’ll continue watching for changes this morning while I get the gear ready.

This is the latest SPC outlook.

20130417-0600-day1otlk_1200

The greatest risk today for the moderate area shown will be large hail and heavy rain. In the Tulsa area, we could see over 2″ of rain today.

20130417-0600-day1probotlk_1200_torn

The moderate risk for tornadoes is nestled in the SW corner of the state. I’d sure like to refine that risk area before I head out.

Locally, the onset for severe will probably be late afternoon and early evening. Looks like I’m going to have to drive to the storms today to get into anything early enough.

More later.

8:16 am

This is why I don’t usually go with my first target area. Things are already changing. The tornado risk area has been enlarged. I’ll be monitoring the models for another couple of hours.

20130417-0814-day1probotlk_1300_torn

11:04 am

The truck is ready. Gear is sitting by the door. I’ll be heading out within the hour. I’m still thinking about heading in the direction of Lindsay and then adjust while I’m on the road.

I’m not expecting this to start really boiling until early afternoon at the earliest. So, I’ve still got some time to get into position.

The site radar is now active. I’ve been having problems with the watch/warning module of my reporting software crashing, so I’ve disabled the graphic on the Live Radar page until the provider gets it fixed. For the most recent watches and warnings, go to: http://www.weather.gov/. The radar images and bulletins on the Live Radar page will be current.

12:59 pm

Grabbing a quick oil change. Be on the road shortly.

1:22 pm

Let the chase begin.  You can follow me through the day on my Twitter feed.

Severe Weather?

3:40 PM

I opted to stay in the Tulsa area today.  May have been the wrong decision.  The first tornado watch was issued for western and central Oklahoma earlier.  If it actually moves to the east, it could be late evening into the overnight hours before anything substantial develops.  Two problems with that.  1.  Chasing at night isn’t a good idea and 2. If something does develop, it’s dangerous for everyone.

So, here I sit.  And wait.  And wait. 

In northeast Oklahoma, we’re under a Flood Watch from 7PM until Sunday morning.  Not what I was anticipating for today.

Worse case scenario?  We get rain and I sit in the comfort of my living room watching things unfold under the cover of darkness.

Hot chocolate anyone?

4:33 PM

The storms are heading to Tulsa.  But, it looks like they’re merging into a big mess.

101312-0432P_tulrad

A little over 2 hours to sunset.  This isn’t looking good for this ole storm chaser.

5:17 PM

Finally.

Severe Thunderstorm Warning for: Nowata, Osage, Pawnee, Rogers, Tulsa and Washington counties in NE Oklahoma.  Effective until 6:15 PM.

Risks:  Damaging wind gusts to 70 MPH.

6:00 PM

Tornado Watch in effect for several counties in NE Oklahoma, including Tulsa county and the city of Tulsa.  This watch is in effect until midnight.

101312.0602P_interwarn_wwa

And radar.

101312.0608P_tulrad

It’s beginning to get a little more interesting.

6:26 PM

Urban/Small Stream Flood advisory issued for Creek, Osage, Pawnee, Rogers, Tulsa and Washington counties.  Effective until 9:15 PM.

This stuff is going to blow through after dark.  Not a good thing.

6:34 PM

Flash Flood Warning issued for Creek, Wagoner, Osage, Rogers and Tulsa counties.  Effective until 10:30 PM.  Downtown Tulsa will likely be impacted by heavy rains and flooding.

101312.0656P_interwarn_wwa

9:35 PM

The storms have moved out of the Tulsa area to the east.  I think it’s safe to say this weather event is over.

Safe travels.
