Areas affected...Texas Caprock vicinity

Concerning...Tornado Watch 355...

Valid 220105Z - 220200Z

The severe weather threat for Tornado Watch 355 continues.

SUMMARY...The supercell tornado threat is likely peaking during the
next hour or so in the Texas Caprock vicinity.

DISCUSSION...Latest radar data from LBB shows an intense/persistent
supercell tracking southeastward in Motley County Texas this
evening. Ahead of this storm, backed east-southeasterly surface
winds beneath around 50 kt 500-mb flow (per 00Z observed AMA
sounding) is contributing to 50-60 kt of effective shear and around
250 m2/s2 effective SRH. Given a corridor of extreme surface-based
instability and a lack of storms nearby, the supercell tornado
threat is likely peaking during the next hour or so, and a strong
tornado is possible.
