   Areas affected...Northwest TX into South-Central OK

   Concerning...Severe Thunderstorm Watch 91...

   Valid 050040Z - 050145Z

   The severe weather threat for Severe Thunderstorm Watch 91
   continues.

   SUMMARY...Severe threat will continue to gradually shift
   east-southeast. Large hail and wind remain possible.

   DISCUSSION...Low-level warm advection is beginning to focus a bit
   east of ww91, primarily along the Red River east of I-35. As LLJ
   begins to shift downstream, deep flow is beginning to veer a bit, as
   evident by ABI VAD profile. A considerable amount of convection
   remains along the cool side of the boundary and organized updrafts
   may struggle to develop appreciably south of the wind shift,
   especially toward Runnels/Coleman County region. In the short term,
   primary severe focus is with the upscale squall line evolving from
   southern Love County OK-eastern Montague-Wise County TX, which will
   soon exit ww91 into tornado watch ww92.
