Concerning...Tornado Watch 229...

Valid 060430Z - 060630Z

The severe weather threat for Tornado Watch 229 continues.

SUMMARY...Supercell thunderstorm initiation now appears underway
across the Pecos Valley into Del Rio vicinity.  A few cells may
undergo considerable further intensification acco*panied by
increasing potential to produce very large hail and perhaps a strong
tornado or two.

DISCUSSION...Increasing and intensifying discrete thunderstorm
development now appears underway across the Pecos Valley. This is
focused within modestly deep surface troughing east-southeast of a
surface low, now centered west-northwest of Fort Stockton, where
boundary-layer moisture characterized by lower 60s surface dew
points has spread as far northwest as the I-20 corridor to the
southwest of Midland/Odessa.  This is contributing to mixed-layer
CAPE on the order of 2000-3000 J/kg.

With further weakening of inhibition, strengthening convection
rooted within this environment will pose the greatest potential to
undergo rapid intensification, supported by both strong deep-layer
shear and now enlarged, clockwise-curved low-level hodographs along
a southeasterly low-level jet (40-50 kt around 850 mb).  This
environment appears potentially conducive to a couple of intense
supercells posing a risk for very large hail and perhaps a strong
tornado or two.
