The nearest sounding before it
Midland Regional, TX (KMAF), launched 00:00Z, 3.9 hours before the alert went out and 68 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Areas affected...portions of southwestern Texas
Concerning...Severe Thunderstorm Watch 404...
Valid 100351Z - 100515Z
The severe weather threat for Severe Thunderstorm Watch 404
continues.
SUMMARY...Severe hail should accompany ongoing supercells for at
least a few more hours. Propagation of the southern end of an MCS is
possible, which may also pose a severe gust threat.
DISCUSSION...Multiple mature, sustained supercells continue to
traverse the immediate cool side of a residual outflow boundary from
yesterday's storms, where 2000-3000 J/kg MLCAPE and 40-50 kts of
effective bulk shear remain in place. MRMS mosaic MESH data
continues to show potentially very large hail falling with multiple
supercells, so severe hail potential should continue in the near
future.
The south end of a mature QLCS may be propagating southeastward
along the residual outflow boundary. If this convection can mature
further, a severe gust threat may manifest.
