...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS SOUTHERN TX...

CORRECTED FOR THUNDER LINE

...SUMMARY...
Isolated severe storms may develop across parts of southern Texas,
mainly this evening into tonight. Large hail, locally damaging
winds, and a brief tornado are possible.

...Southern TX...
A slow-moving cold front will become quasi-stationary across the
coastal plain into the Brush Country today. Neutral mid-level height
change is expected over the warm sector, downstream of a dampening
shortwave trough ejecting from the Gulf of CA towards the TX
Panhandle. However, an increase in low-level warm air advection will
occur along and north of the front this evening, likely yielding
scattered, mostly elevated storms across parts of central TX.
Farther east, weaker warm-air advection should still be sufficient
for isolated storms forming across the coastal plain overnight. 

While low-level moisture should remain rich within the warm sector,
relatively warm upper-level temperatures as sampled by 12Z Corpus
Christi and Brownsville soundings should limit total buoyancy. In
conjunction with 35-45 kt effective shear and modest low-level
hodographs, setup should favor weak, transient updraft rotation in a
few cells embedded within a predominant cluster-type mode. Isolated
severe hail appears to be the main hazard, but locally damaging
winds and a brief tornado may occur, considering the high quality
low-level moisture.
