Areas affected...Portions of central TX

Concerning...Tornado Watch 94...

Valid 091712Z - 091845Z

The severe weather threat for Tornado Watch 94 continues.

SUMMARY...A threat for tornadoes, hail, and damaging winds
continues. The need for and timing of a downstream watch into east
Texas remains unclear.

DISCUSSION...Thunderstorms have remain focused along/very near the
convectively reinforced outflow boundary that is draped southwest to
northeast across central TX. Mergers/interactions between various
thunderstorms have led to an overall messy convective mode. Even so,
the environment remains conditionally favorable for severe
convection, including supercells, given adequate instability and
ample deep-layer shear. In the short term, the tornado threat will
continue to be supported by a 30-40 kt south-southwesterly low-level
jet providing generally 200-300 m2/s2 of effective SRH. But, the
best chance for tornadoes will probably occur with any supercell
that can develop/persist on the southern flank of the ongoing
convection. Similarly, the hail threat will be tied to a supercell
being able to remain at least semi-discrete, which remains
questionable given the ongoing thunderstorm evolution.
Severe/damaging wind potential may increase through the early
afternoon if a cluster can consolidate and spread eastward. The need
for and timing of a downstream watch into east TX remains uncertain,
as widespread cloud cover is slowing airmass recovery along/near the
surface boundary in the wake of earlier convection.
