   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
   THE RIO GRANDE VALLEY...

   ...SUMMARY...
   Marginally severe thunderstorms, associated with hail and strong
   gusty winds, will continue for another hour or so in parts of the
   Rio Grande Valley of southeast Mexico and far West Texas.

   ...Rio Grande Valley...
   The latest water vapor imagery has an upper-level ridge over central
   New Mexico. Scattered thunderstorms are ongoing in the vicinity of
   the ridge from central New Mexico southward into far West Texas. At
   the surface, a 1001 mb low is located in far southeast Arizona.
   Upslope easterly flow is present to the east of the low across much
   of west Texas and southeast New Mexico. Within this airmass, surface
   dewpoints of 45 to 50 F and temperatures in the 80s F are
   contributing to MLCAPE around 1000 J/kg. Although 0-6 km shear is
   very weak, 0-3 km lapse rates on the 00Z sounding from Albuquerque
   are near 10 C/km. This thermodynamic environment should be
   sufficient for marginally severe multicells over the next hour.
   Isolated damaging wind gusts and hail will be possible.
