Areas affected...Central Texas
Concerning...Severe potential...Watch unlikely=20
Valid 301549Z - 301745Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated occurrences of marginally severe hail are
possible this morning. A watch is not anticipated.
DISCUSSION...Elevated thunderstorms ongoing across portions of the
Concho Valley and Hill Country have exhibited episodic
intensification with volumetric radar data indicating some mid-level
rotation with the strongest storms. The 12z DRT sounding suggests
that convection is likely rooted around 850 mb, with modestly steep
mid-level lapse rates of around 7.5 degrees C/km contributing to
MUCAPE of 2500-3500 J/kg, at least in the Edwards Plateau region.
However, more recent RAP-based forecast soundings suggest that
parcel buoyancy is considerably weaker (500-1000 J/kg) farther east
within the immediate inflow region of the ongoing storms, which may
tend to limit the overall intensity of that convective regime.=20
Nonetheless, the presence of 55-65 kt of effective bulk shear will
be supportive of transient supercell structures, potentially capable
of marginally severe hail.=20
Current thinking is that any severe weather threat is expected to
remain too limited in areal coverage and magnitude to warrant the
issuance of a Severe Thunderstorm Watch.
