   Areas affected...Western OK and the southeast TX Panhandle

   Concerning...Tornado Watch 144...

   Valid 271424Z - 271600Z

   The severe weather threat for Tornado Watch 144 continues.

   SUMMARY...Severe storm threat will increase through midday across
   the southeast Texas Panhandle into west-central and southwest
   Oklahoma.

   DISCUSSION...Convection along and ahead of the dryline across the
   southeast TX Panhandle into west-central OK has thus far largely
   struggled to turn the corner and produce severe weather yet this
   morning amid several candidate updrafts. Insolation ahead of this
   activity is greatest in western north TX from the CDS vicinity
   southward. It is plausible that sustained supercell development may
   evolve from the Hale County storm as it tracks along the 67 F
   isodrosotherm into southwest OK, as weak MLCIN noted in 12Z
   soundings erodes. Large hail will the primary initial threat with
   tornado potential increasing into early afternoon amid a 40-45 kt
   southerly low-level jet per FDR VWP data.
