Areas affected...Portions of the Permian Basin and the Edwards
Plateau

Concerning...Severe Thunderstorm Watch 637...

Valid 232330Z - 240130Z

The severe weather threat for Severe Thunderstorm Watch 637
continues.

SUMMARY...Strong/severe thunderstorms remain probable in the coming
hours across portions of the Permian Basin/Edwards Plateau where the
convective environment remains very favorable for organized
convection.

DISCUSSION...Latest radar imagery from KMAF shows a broken line of
thunderstorms between the I-20 and I-10 corridors west of the San
Angelo, TX region. While most cells remain fairly weak, a leading
supercell has shown periodic intensification and a persistent,
albeit weak, mid-level mesocyclone. Despite the meager intensity
thus far, these cells are beginning to move into the axis of better
low-level moisture where MLCAPE is regionally maximized (between
1000-1500 J/kg). Regional VWPs continue to sample elongated
hodographs featuring 0-6 km BWD values on the order of 50-60 knots.
As such, the regionally best convective environment remains
immediately downstream of ongoing cells, which may support an uptick
in convective intensity in the coming hours. Additionally, new
updraft development is noted in IR imagery on the southwestern flank
of the broken band, hinting that an increase in thunderstorm
coverage is probable. Recent CAM solutions support this idea and
suggest thunderstorm coverage may be maximized in the coming hours.
