Areas affected...Texas Hill Country...Permian Basin
Concerning...Severe potential...Watch unlikely
Valid 112053Z - 112330Z
Probability of Watch Issuance...20 percent
SUMMARY...A few of storms may become strong enough to briefly
produce hail and/or damaging gusts from the Permian Basin into the
Texas Hill Country this afternoon.
DISCUSSION...Recent satellite imagery shows a well-defined outflow
boundary just ahead of the showers and thunderstorms over central
TX. Convergence along the western portion of the boundary likely
contributed to the initiation of the robust thunderstorm over
Schleicher County TX. The airmass downstream of this outflow is
moist, with dewpoints in the upper 60s/low 70s, but warm
temperatures aloft are mitigating the overall buoyancy. Recent
mesoanalysis estimates MLCAPE from 1000 to 1500 J/kg. Vertical shear
is modest as well, with mesoanalysis estimating effective bulk shear
is currently around 30 kt. Even so, persistent low-level convergence
along the outflow boundary, particularly the western portion of the
boundary, will likely lead to the development of additional
thunderstorms. A few of these storms may become strong enough to
briefly produce hail and/or damaging gusts. Isolated coverage and
limited intensity and duration is anticipated, precluding the need
for a watch.
