Areas affected...part of the Texas Edwards Plateau vicinity
Concerning...Severe potential...Watch possible=20
Valid 072304Z - 080100Z
Probability of Watch Issuance...60 percent
SUMMARY...Thunderstorm activity is slowly increasing with further
upscale growth possible into mid to late evening, accompanied by a
risk for severe hail initially, then perhaps a few strong surface
gusts later this evening. The risk for tornadoes appears low, but
perhaps not out of the question.
DISCUSSION...Thunderstorm activity is in the process of initiating near/southwest through northwest of San Angelo. This appears
focused along a diffuse dryline structure, near its intersection
with a baroclinic zone within broad weak surface troughing.=20
Although mid-level lapse rates do not appear particularly steep, a
fairly deep moist boundary may be contributing to CAPE up to 1500
J/kg, beneath strong, broadly difluent southwesterly mid/upper flow.
Despite generally weak to modest low-level forcing for ascent,
continuing moist unstable inflow in the presence of weakened
mid-level inhibition may be sufficient to support a gradual further
increase in convective development and upscale growth. Given the
environment, this may be accompanied by a risk for severe hail in
stronger storms initially, then perhaps some increase in potential
for strong surface gusts later this evening as activity slowly
shifts northeastward/eastward.
