Areas affected...TX South Plains

Concerning...Severe Thunderstorm Watch 351...

Valid 300553Z - 300800Z

The severe weather threat for Severe Thunderstorm Watch 351
continues.

SUMMARY...Slow-moving, but potentially long-lived supercell should
persist across a portion of the Texas South Plains as it likely
tracks east-southeast through the pre-dawn hours. A narrow swath of
occasional significant severe wind and hail is possible.

DISCUSSION...A slow-moving supercell centered on northeast Roosevelt
County, NM appears to have finally be turning to the east-southeast
from its initial south-southeast track. This storm has a history of
reported very large hail to 2.5 inches at Cannon AFB last hour. West
TX Mesonet obs confirm a plume of low to mid 60s surface dew points
immediately ahead of this supercell across the TX South Plains. With
larger buoyancy and a stronger low-level jet relative to last
night`s intense supercell that similarly tracked across the region,
it is plausible that this supercell may become a long-lived one as
it moves toward the I-27/US-87 corridor. A narrow swath of
significant severe hail is possible early, with an increasing risk
for significant severe wind as supercell bowing structures
potentially develop.
