Valid 292331Z - 300030Z
Probability of Watch Issuance...80 percent
SUMMARY...Severe thunderstorm watch appears warranted for South
Central Texas. Large hail and damaging winds are expected.
DISCUSSION...Strong instability lingers across south central TX
early this evening and convection is beginning to deepen in
proximity to the surging cold front. Thunderstorms are expected to
mature along/just behind the wind shift from Falls County into
Williamson County over the next hour, then southwest to near or just
east of the San Antonio metro. Large hail and damaging winds will
likely accompany this upward-evolving frontal convection. WW will
likely be issued soon.
