   Concerning...Severe Thunderstorm Watch 181...

   Valid 290327Z - 290430Z

   The severe weather threat for Severe Thunderstorm Watch 181
   continues.

   SUMMARY...An isolated severe threat is expected to develop across
   parts of south Texas late this evening. The threat should remain
   marginal, and additional weather watch issuance is not anticipated.

   DISCUSSION...The latest radar imagery from the Brownsville WSR-88D
   shows a line of strong to severe thunderstorms straddling the
   Mexico-U.S. border near Falcon Village, Texas. A supercell is
   ongoing right along the river. This storm will likely hold together
   for another hour or two, with potential to produce wind damage and
   isolated large hail. Other storms may also develop and move into
   south Texas. However, as instability weakens late this evening, the
   severe threat should become more isolated with time. For this
   reason, additional weather watch issuance appears unlikely.
