Areas affected…east central/southeast New Mexico and the Texas
South Plains
Concerning…Severe Thunderstorm Watch 684…
Valid 160356Z – 160600Z
The severe weather threat for Severe Thunderstorm Watch 684
continues.
SUMMARY…Scattered strong thunderstorm development may persist, and
pose a continuing risk for occasional severe hail and locally strong
wind gusts, while spreading southward across the Texas South Plains
and adjacent portions of eastern New Mexico through 1-3 AM CDT.
DISCUSSION…In general, there has been little change to convective
trends along the southward advancing front to the lee of the
southern Rockies during the past couple of hours. The corridor of
weak frontogenetic forcing is still providing the primary focus for
strong thunderstorm development, which remains largely discrete and
scattered in nature while propagating south-southeastward.
With warm advection above the frontal zone remaining weak, and the
modest pre-frontal boundary-layer instability beginning to wane,
potential for appreciable upscale convective growth and organization
appears low, as the cold front advances toward the Trans-Pecos
region through 06-08Z. However, lingering scattered strong
thunderstorms may continue to occasionally pose a risk for severe
hail and locally strong surface gusts.
