Areas affected...southwest Texas
Concerning...Severe Thunderstorm Watch 182...
Valid 300139Z - 300315Z
The severe weather threat for Severe Thunderstorm Watch 182
continues.
SUMMARY...Isolate to widely scattered elevated supercells will
continue to pose a risk for severe hail this evening.
DISCUSSION...As of 0135 UTC, regional radar analysis showed several
new storms had developed across WW182 in the last two hours.
Organization has been noted with several of these storms displaying
fairly strong mid-level rotation. These storms are likely elevated,
north of the sagging front/outflow.
Still, a broad reservoir of elevated buoyancy remains in place
across southwest TX with 3000-5000 J/kg of MUCAPE and steep
mid-level lapse rates (DRT/MAF RAOBs). Effective shear is also
robust with 50-60 kt of deep-layer zonal flow overspreading the
region. This should continue to support supercells with significant
hail potential (2-3") along the Rio Grande Valley and Southwest TX
this evening.
