   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
   WESTERN TEXAS PANHANDLE AND FAR NORTHEASTERN NEW MEXICO...

   ...SUMMARY...
   Scattered storms in the western Texas Panhandle and far northeastern
   New Mexico will pose a marginal risk for damaging winds through
   sunset.

   ...Western Texas Panhandle and far northeastern New Mexico...
   Scattered thunderstorms have developed and begun to slowly propagate
   northeastward across the area.  These storms are propagating through
   an axis of moderate instability that will aid in a continued,
   although isolated, damaging wind threat into the early overnight
   hours.  Storms should undergo a weakening trend after dark with the
   onset of nocturnal boundary layer cooling and stabilization.  

   ...Central/Southwestern Nebraska...
   Southward-moving linear segments continue to propagate across the
   region currently.  Storms have generally been sub-severe, with
   downdraft cores well-separated from gust fronts - characteristic of
   an environment containing weak low-level shear.  A weakening trend
   should commence soon as nocturnal boundary layer cooling commences,
   lessening an already marginal risk for hail/wind damage.  As such,
   severe probabilities have been removed for this outlook update.
