Pointing to the target area east of Plainview on the 1:00
PM surface map. |
 |
Looking north at the first wall cloud. |
 |
Close-up of the eastern edge of the wall cloud. |
 |
Looking east at the first brief tornadic dust whirl
produced by the storm. This tornado occurred on the eastern side of the wall cloud
coincidentally with an intense RFD burst, barely missing a farmer's home. |
 |
Looking NNW at a dissipating meso on the left, and a
strengthening meso on the right with a tornadic dust whirl underneath. |
 |
Looking north at a multiple-vortex tornado. Veteran storm
chaser David Hoadly was shooting video of this event from the side of the road as I drove
by. |
 |
One of many sub-vortices seen rotating around the larger
tornadic circulation. |
 |
Another sub-vortex a few seconds later. The image is grainy because I digitally
enhanced the contrast to make the vortex easier to see. |
 |
Looking north as a tornado developed just WNW of South
Plains, Texas. |
 |
Looking NNE as the tornado pictured above developed,
another larger circulation was barely visible in the dark shadows underneath the large
mesocyclone, to the NW of South Plains. |
 |
Several minutes later, several miles southeast of South
Plains and a few miles northwest of Dougherty, looking north at a tornado located on the
southwestern edge of the meso. Note the lightning and funnel at the top and bottom of the
image. |
 |
Looking NNE at a second tornadic dust whirl, also located
on the southern edge of the meso. |
 |
The tornado continued to develop. |
 |
The tornado moved just east of a farmer's
home. |
 |
|
 |
The tornado reached its maximum intensity. |
 |
The tornado's dissipation was heralded by a brilliant
staccato CG. |
 |
Looking ENE, another tornadic dust whirl developed along
the RFD / inflow shear line just SE of where the previous tornado dissipated. |
 |
Looking east as a burst of RFD blasted the circulation. I
believe this dust plume was the one seen in Doswell's video which coincided with the
multi-vortex stage of the quickly developing tornado, and immediately preceded the
formation of the wedge tornado. Chuck was southeast of the developing tornado. A note for
spotters, again the "back side", in this case west of the updraft which was
where I was located, provided poor visibility, while the area ahead and southeast of the
tornado, where Chuck and Al were located, provided a high contrast view, as evidenced by
Chuck's video. However, Al and Chuck had to drive rapidly southward to stay ahead of the
southeastward moving tornado. |
 |
Looking east, the dust dissipated as rotation focused on
the developing wedge tornado hidden in the shadows to the left. |
 |
Looking WNW at my first glimpse of the rapidly intensifying
wedge tornado. Chuck Doswell videoed the large tornado, as Al Moller photographed it from
a location near Dougherty, Texas. Al and Chuck were a few tens of seconds ahead of me on
this road. They had noticed a developing tail cloud further east and did not slow down as
I did to view the smaller tornadoes pictured above. They drove east on this road and
turned south before their path was blocked by the tornado. They made a gutsy move that
paid big dividends. I believe that I was actually closer than they were, but their
view was not blocked by dust and rain curtains. |
 |
Visibility was poor due to blowing dust and wrapping rain
curtains. The following series of video stills show my approach toward the large tornado.
The contrast was electronically enhanced, but otherwise, these images are unmodified. The
left side of the tornado is clearly visible in the images. Visually, I could also see the
right side of the tornado. I considered driving closer, but I was not sure how far it was
to the "south option" shown ahead on my map. Concerned about large hail and
additional satellite tornadoes, I opted to turn around and try to intercept the tornado
farther south. I had to negotiate the traffic lights in Floydada before I could turn east
and intercept the storm. |
 |
The next several images are grainy as a result of digital processing to enhance the
contrast. The tornado was partially obscured by dust and wrapping rain curtains. |
 |
|
 |
Looking east - note the right side of the wedge was
straight ahead down the road. |
 |
My closest approach - approximately 3/4s of a mile west of
the tornado. Concerned about large hail, I made a u-turn and quickly left the area to
attempt an intercept farther south. |
 |
Farther southeast near Jayton, Texas, Bruce Haynie
photographed the storm structure of a severe hailstorm that developed on the southwest
side of the thunderstorm complex. |
 |
|
 |
The storm resembles a bull elephant, with inflow clouds
resembling his trunk and tusks. |
 |
|
 |

 |
|
 |
The storm dissipated shortly after sunset. |
