   ...West TX...
   A closed mid-level low in the southern stream near the Gulf of CA
   should progress into northern Chihuahua by 12Z. While steep
   mid-level lapse rates are not progged to translate east of Sonora,
   minimal MUCAPE (up to around 100 J/kg) might spread across the
   international border as far east as the Permian Basin and Edwards
   Plateau. A couple lightning flashes may be possible in the early
   morning within the warm/moist advection regime downstream of the
   closed low. Given the modest forcing for ascent amid flimsy buoyancy
   and weak upper lapse rates for charge separation, overall thunder
   probabilities appear to be less than 10 percent.
