- Chase Area: Northwest Texas
- Amos Magliocco and I left Fort Worth at 10am
with an initial target around I-20 near Eastland, Texas. Our target was fluid as we
wanted to see how far north the warm front lifted as well as if instability developed
north of I-20. We ate lunch at a cafe in Ranger, Texas, and at 1pm we watched the
front lift north quickly past Ranger. We met up with Tony Laubach and gain from
Colorado. We drove north on Hwy 183 towards Throckmorton and continued north to
Seymour where we calculated that we would meet the storm just before it reached town.
SPC mesoanalysis showed CAPE of 3000 J/Kg just south of the warm front.
Storms fired along the dryline and quickly moved northeast, slowing and
intensifying as they hit the warm front.
- Strong Supercell - Seymour, Texas
- As we approached the storm, we could see a
shelf with outflow surging out, with a lowering further north. The updraft was
rotating hard, with some hint of structure.
-
- Rapidly Developing Tornado - Seymour, Texas
- Very strong RFD cut into the updraft which
rapidly intensified the low level mesocyclone. We began to see tennis ball to
baseball hail falling with rapid rain curtains. Multiple vorticies began to touch
down around 1938 UTC. The center image shows the tornado as it crossed the road
behind the white sign. This did damage to trees and power lines on Hwy 183 south of
Seymour, Texas.
-
- Wedge Tornado - Seymour, Texas
- This tornado rapidly developed into a wedge,
estimated at a half mile wide width. The motion at the ground level looked violent
as it drilled into the ground. We lost sight of it at around 1944 UTC. We
tried to call this into the NWS and had trouble, but Tony called it into 911, which called
us back 5 minutes after we lost sight of it, saying it was still on the ground.
-
- Baseball Hail - Seymour, Texas
- As we drove into Seymour, we observed a
large swath of baseball hail that covered much of the city as well as street flooding.
