The radar
The Midland/Odessa radar (KMAF), 19 km from the middle of the area, began a volume at 19:19 UTC, the scan nearest the moment this went out.

The nearest sounding before it
Midland Regional, TX (KMAF), launched 12:00Z, 7.3 hours before the alert went out and 18 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.

Concerning...Tornado Watch 253...254...
Valid 021918Z - 022045Z
The severe weather threat for Tornado Watch 253, 254 continues.
SUMMARY...The threat for very large to giant hail and a couple of
tornadoes will continue through the afternoon.
DISCUSSION...Intense supercells are ongoing at 1915 UTC near Fort
Stockton, TX, and also just east of Hobbs, NM. The 18Z MAF sounding
modified for recent surface obs depicts a very favorable hail
environment, with MLCAPE greater than 2500 J/kg and sufficient
deep-layer shear for supercells. The ongoing supercells will
continue to pose a threat for very large to giant hail as they
spread east/southeastward through the afternoon.
Tornado reports have been received from each of this pair of
supercells. While low-level shear/SRH will likely remain somewhat
marginal, favorable low-level thermodynamics and the presence of
ongoing intense supercells will continue to support some tornado
threat through the afternoon.
Another supercell has recently developed across extreme southeast
NM, and additional supercell development will be possible through
the afternoon along a weak surface trough, and also potentially
along the trailing outflow from the Fort Stockton supercell.
