   Areas affected...The Texas Panhandle

   Concerning...Tornado Watch 144...145...

   Valid 080125Z - 080300Z

   The severe weather threat for Tornado Watch 144, 145 continues.

   SUMMARY...The severe weather threat continues across tornado watch
   144 and 145 with a threat for large hail, damaging winds, and
   isolated tornadoes.

   DISCUSSION...Convective coverage has increased significantly across
   the Texas Panhandle over the past hour as the low-level jet
   strengthens and deep layer ascent increases. This activity is likely
   to congeal into an MCS with an increasing severe wind threat, but it
   remains unclear how this will evolve. The last several runs of the
   HRRR suggested that storms northwest of Lubbock would be the
   beginning of a bowing segment that would move northeastward,
   however, earlier storms have worked over this airmass somewhat
   already. Therefore, it remains unclear whether these storms will be
   able to organize with eastward extent.

   Additionally, a line of storms have developed along the TX/OK border
   with additional development on the southern edge. This line of
   storms may also be the beginning of the forward propagating MCS. 

   Regardless of the exact evolution, increasing forcing for ascent in
   an unstable and moderately sheared environment will continue to
   support all severe weather hazards including large hail, damaging
   winds, and isolated tornadoes.
