   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 94 CONTINUES.

   SUMMARY...A SMALL AREA NEAR AND WEST OF THE CORPUS CHRISTI VICINITY

   DISCUSSION...THE SUPERCELL WEST OF THE CRP AREA IS GETTING BETTER
   ORGANIZED WITH WEAK BUT BROAD LOW-LEVEL CONVERGENCE NOTED ON SWRN
   FLANK OF THE STORM AND STRENGTHENING MID-LEVEL ROTATION. TRENDS ALSO
   INDICATE A CONTINUED VEERING OF THE STORM MOTION. IN
   ADDITION...OTHER CELLS ARE DEVELOPING TO THE E AND SE OF THIS
   CELL...FURTHER INDICATING A CONTINUED ENHANCEMENT TO THE
   PROPAGATIONAL COMPONENT TO THE MOTION. 

   ALTHOUGH LOW-LEVEL LAPSE RATES ARE WEAK...THIS STORM MAY EVENTUALLY
   ATTEMPT TO PRODUCE A TORNADO GIVEN LOCALLY-BACKED SURFACE WINDS TO
   THE E. THE CRP VWP CONTINUES TO BE STRONGLY-SUPERCELLULAR...ALTHOUGH
   LOW-LEVEL SRH IS NOT PARTICULARLY HIGH. STILL...A BRIEF TORNADO
   COULD OCCUR GIVEN THE ORGANIZED NATURE OF THIS CELL. EVEN IF A
   TORNADO DOES NOT OCCUR...THE DAMAGING WIND AND HAIL THREAT WILL BOTH
   BE ENHANCED.
