   Valid 021630Z - 031200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Very isolated thunderstorms may brush the Texas Big Bend this
   evening.

   ...TX Big Bend...
   Scattered convection that can be sustained across parts of Chihuahua
   during the late afternoon and early evening may brush the
   international border area as it weakens through the evening. While
   surface-based parcels are expected to be capped with plentiful MLCIN
   in southwest TX, weak moist advection near 700 mb may yield meager
   elevated buoyancy within the steep lapse rate environment. The lack
   of stronger forcing for ascent suggests thunderstorm probabilities
   are only around 10 percent.
