MD 1073 CONCERNING SEVERE THUNDERSTORM WATCH 351… FOR TX SOUTH PLAINS
Mesoscale Discussion 1073
NWS Storm Prediction Center Norman OK
1253 AM CDT Thu May 30 2024
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.
