...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EVENING OVER PARTS OF WEST TX....
...SUMMARY...
A few severe storms capable of large hail will be possible this
afternoon and evening across parts of west Texas.
...West TX...
Current satellite imagery shows a well-defined upper low over AZ,
with a band of showers and embedded thunderstorms preceding it
across central/eastern NM. This low is forecast to continue
northeastward throughout the day as a belt of strong mid-level flow
pivots through its southern and eastern periphery across the
southern High Plains and into the southern/central Plains. Low-level
moisture will continue to advect northwestward ahead of this low and
associated jet streak and model consensus brings upper 50s dewpoints
into the Permian Basin by this evening. This should result in a
relatively confined region of surface-based buoyancy across the
Permian Basin, which will combined with large-scale ascent and
strong shear to support supercells. Primary threat will be large
hail, although the anticipated development of surface-based buoyancy
does indicate a low-probability threat for strong winds and/or a
tornado.
Low-level stability will increase quickly with eastward extent, as a
result of both nocturnal cooling and generally cooler surface
temperatures throughout the day. Even so, enough elevated buoyancy
is anticipated for continued strong to occasionally severe storms
throughout much of the evening and overnight, particularly in the
03Z-06Z time frame across southwest TX. Hail is the primary risk
with these storms.
