Areas affected...Southern High Plains

Concerning...Severe Thunderstorm Watch 244...246...

Valid 272153Z - 280000Z

The severe weather threat for Severe Thunderstorm Watch 244, 246
continues.

SUMMARY...Isolated severe thunderstorms will spread east across the
southern High Plains this evening. Large hail is the primary risk
with this activity. New severe thunderstorm watch may be warranted
downstream into the TX High Plains to account for this risk.

DISCUSSION...Water-vapor imagery suggests a weak mid-level
short-wave trough is translating across central NM/far west TX.
Scattered convection has developed ahead of this feature, along the
western fringe of higher moisture/instability where southeasterly
boundary-layer flow is evident. Latest diagnostic data suggests a
surface boundary, augmented by early-day convection, is draped from
near I-20, north of ABI, into southeast NM. LLJ should strengthen a
bit after sunset across the High Plains and ongoing convection over
southeast NM should propagate east, aided by aforementioned short
wave. Ample buoyancy, and modest shear, exist across this region
such that ongoing convection should be maintained deep into the
evening.
