   Areas affected...Portions of the Rio Grande Valley

   Concerning...Severe potential...Watch likely 

   Valid 290047Z - 290215Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Severe wind gusts near 60-70 mph and marginally severe
   hail will accompany a developing MCS through the late evening hours.

   DISCUSSION...Several robust updrafts, and a couple of supercells,
   will continue moving eastward off the higher terrain of Chihuahua
   Mexico. Cell mergers appear likely, and the downstream environment
   remains favorable for maintenance considering easterly surface winds
   around 15 to 20 kt. Convergence zone balance is anticipated between
   this surface flow and westerly 0-3 km shear vectors. In addition, a
   very unstable and undisturbed air mass remains in place across south
   Texas.
