It's 11AM and I woke up to take a final look at the
Day 1. The SPC had hatched off an area in West Texas. Chances
of an F2-F5 tornado were around 20% along with the given
chances of large hail and damaging winds. The SPC had also
centered its moderate risk around this area. I made the
decision that Throckmorton, TX would be my target area. At
11:30AM my chase buddy and navigator Kevin Sims came over. We
made final preparations to the car and the camera equipment.
At 11:45 we hit the roads and headed towards Throckmorton. We
jumped on 635 and headed West, then got on I35 and went South.
Eventually we hit I20 and went West. Then we went North and
got on 380. About this time the first Tornado Warning had been
issued for Fisher County. The storm was Northwest of us and
moving East. We were about 10 minutes from the Jones / Haskell
line and were hauling North to intercept the storm in time.
Finally we hit Haskell just South of Throckmorton when the
second Tornado Warning was issued for the Southwest Haskell /
Jones county line. With the storm moving due East and us being
on the Southeast side of the Haskell County line, we had to
decide whether we were going to punch the storm and risk
driving into baseball sized hail, or go back South a ways and
let the storm pass in front of us. While we were deciding, we
were parked on the side of the highway watching the storm move
closer. At this time we could see the wall cloud and a
possible roping-stage funnel through the rain / hail shaft. We
did debate; however, whether we thought it truly was a
funnel, or just scud because the "funnel" was at such a far
distance. Clocking 25 MPH inflow winds, I decided we should
head South a bit. I hoped that we would be able to view some
nice structure while being on the "safe side" of the storm. We
headed South, and ended up parking on the side of the highway
observing the storm with a few other chasers and a couple TV
media crews. The structure by now was awesome! While standing
in the 43 MPH inflow jet we observed a rock solid wall cloud
and updraft. We decided the storm was getting very close so we
moved South and watched the wallcloud disorganize and disappear
into the hail and rain shaft. Being in communication with the
National Weather Service, the group headed East hoping more
storms would fire up along the line. Taking 287 East we ran
into an area of golf ball to baseball sized hail. The group was
talking and hanging back so Kevin and I decided we were going
to keep moving. We broke up from the group and took Highway 16
through Graford towards Mineral Wells. Storms never did fire
up, but the Dallas area did get the remains of the storms we
had chased. On Highway 16, we met up with Eric Nguyen who was
observing a large bird; possibly a pelican, that had been hit
by hail and fell to it's death. We all ended the day by going
to a Pizza Hut for dinner and heading home with some really
cool pictures and watching a great lightning show...

Moderate Risk issued for today. Left the house
around 12PM with my friend and chase buddy for the day, J.J..
We went North on I35 and really
tried to get North fast because I knew we had left a little
later than we should have. We passed through Denton, then
Ardmore and eventually got up to the Norman area. When we got
to Norman we hit Highway 9E and hauled East. We could see an
awesome storm exploding just to our East and it had a really
nice anvil on it. It looked impressive and quite promising. We
drove on 9E for quite awhile, probably close to 45 minutes
then hit I69. We finally got to the HP cell and ended up
punching it. We went South on 69 thinking maybe it would give
us more East options. While on 69 the NWS had issued a Tornado
Warning for our county right near where we were. On 69 in
McAlester we got hit by what we believe to be RFD. We got some
really strong winds, and we ended up driving by 2 motorists
who were up in the top of some girders of an overpass for some
reason. Since everything was HP we couldn't see what the heck
it was, but we turned around and went North on 69 in hopes to
catch up with it anyway. We figured the day was over until I
checked out the TV and watched the local TV radar. We got back
on 9E and went East further towards Haskell County, and thats
when the sirens began to go off. In Haskell, we sat on the
side of the road and watched a rotating lowering, or the more
popular belief of scud to peek it's way through a lowering and
rain / hail shaft. Most likely it was the same storm that had
hit McAlester earlier, just moving NorthEast. At the time I
had thought it was a funnel because of it's nice rotation and
rope shape lowering from the cloud. It got real close and we
ended up only having 1 escape route...to turn around and go
the opposite way being chased by this stuff. We turned around
and drove a little further and watched the lowering go back up
into the cloud base. Unfortunately I didn't get any pictures,
just video. We went through Stigler. About this time it was
dark and we couldn't see much. Lightning lit up our second
possible wall cloud, which I am sure of because I myself could
see a definate wall cloud. It too, had a Tornado Warning
issued on it as we started chasing it. We went South on 82,
then West on 31 then back North on Highway 2. Then, my parter
and the rest of the "EM" guys said they saw debris. So it was
either a funnel with a wall cloud, scud, or possible tornado.
I began to see power flashes that weren't associated with
lightning so I started to wonder. It was night time, so I
suppose it could have been anything. Theory is, it too, was
scud. I haven't heard of many damage reports from that area,
so I wouldn't disagree. It could have very well been scud. I
was driving through rain and keeping my eyes on the road, so I
unfortunately couldn't get a good look at that storm either.
The sirens went off and we went North a little more.
Unfortunately, something happened where we ended up in the
direct path of another tornado warning. I'm still confused
about what the hell happend. All of us wern't even sure if
there was a tornado but the NWS seemed confident with their
radar and the sirens we're going off and we were in the direct
path. So, we all got out of our cars to be safe and attempted
to get into a locked building. With that not successful, we
stood in the rain trying to figure out what we were going to
do. We started to get heavy rain, then small pea-sized hail,
and then really strong winds. Suddenly the winds shifted and
went the exact opposite direction. It was pretty cool. After
that, I felt I had enough for one day! We went West on Highway
9, and back South on I69 through McAlester until we hit I75.
Chase day ended, with nothing but scud and a possible wall
cloud or possible funnel with a less likely
tornado. Remember:
Oklahoma EMERGENCY
MANAGEMENT claimed it was a
tornado. So thats what I
base the "tornado"
off of.

MID AFTERNOON OVER THE WESTERN TEXAS PANHANDLE...AND
STORMS SHOULD EXPAND EAST AND SOUTHEASTWARD TOWARD
SOUTHWEST OKLAHOMA BY TONIGHT. VERTICAL WIND SHEAR AND
INSTABILITY WILL BOTH INCREASE ACROSS THE TEXAS PANHANDLE
AND WESTERN OKLAHOMA THROUGH EARLY TONIGHT...THUS STORMS
