   NWS STORM PREDICTION CENTER NORMAN OK

   AREAS AFFECTED...SCNTRL THROUGH SERN TX

   CONCERNING...TORNADO WATCH 192...

   VALID 280145Z - 280245Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 192 CONTINUES.

   SUMMARY...WITH THE EXCEPTION OF THE AREA NEAR SAN MARCOS...SEVERE
   THREAT IS BECOMING INCREASINGLY LIMITED ACROSS THE REMAINING PART OF
   TORNADO WATCH 192. THIS WW IS SCHEDULED TO EXPIRE AT 04Z...BUT MUCH
   OF IT CAN BE CANCELLED BEFORE ITS EXPIRATION TIME. LONE STORM
   CURRENTLY OVER TRAVIS AND HAYS COUNTIES NEAR SAN MARCOS MAY CONTINUE
   TO POSE A SEVERE THREAT THROUGH AROUND 0230-03Z.

   DISCUSSION...LONE STORM NOW OVER TRAVIS AND HAYS COUNTIES IS MOVING
   SOUTH AT AROUND 25 KT. THIS STORM EXHIBITS AT LEAST MARGINAL
   SUPERCELL CHARACTERISTICS AND MAY BE CAPABLE OF PRODUCING LARGE
   HAIL. VWP DATA SHOW VEERING LOW-LEVEL WIND PROFILES AND 50 KT 0-6 KM
   SHEAR. GIVEN THE STABILIZING BOUNDARY LAYER...THE STORM MIGHT NOT BE
   INGESTING THE VORTICITY IN THE SFC-1 KM LAYER WHICH SHOULD LIMIT
   POTENTIAL FOR A MORE ROBUST TORNADO THREAT. THOUGH A BRIEF TORNADO
   CANNOT BE RULED OUT...THE PRIMARY THREAT WITH THIS STORM APPEARS TO
   BE LARGE HAIL.

   ELSEWHERE ACROSS WW 192...STORMS HAVE DISSIPATED. REDEVELOPMENT
   APPEARS UNLIKELY GIVEN INCREASING CONVECTIVE INHIBITION AND
   LIKELIHOOD THAT DEEPER FORCING FOR ASCENT WITH THE UPPER LOW
   CIRCULATION WILL REMAIN NORTH OF THIS REGION.
