Areas affected...far western Texas
Concerning...Severe potential...Watch unlikely=20
Valid 172242Z - 180045Z
Probability of Watch Issuance...20 percent
SUMMARY...Supercells capable of instances of large hail and damaging
wind likely this evening.
DISCUSSION...Thunderstorm activity has initiated near the surface
dryline across far western Texas, near Fort Stockton, TX. Ahead of
the dryline, temperatures exceed 100 F with dew point in the mid 40s
to upper 50s. A gradient of MLCAPE around 1000-1500 J/kg is observed
in surface objective analysis, along with deep layer shear around
40-45 kts, with strong mid-level capping to the east of the dryline.
Given strong deep-layer shear and sufficient MLCAPE, steep lapse
rates, and large dewpoint depressions, high-based supercell
thunderstorms capable of instances of large hail and damaging winds
will be possible. Forcing is largely focused along the dryline and
near terrain features. With downstream inhibition, storm coverage
is likely to remain fairly isolated.
