   EARLIER BOW ECHO THAT MOVED THROUGH AREAS NEAR/WEST OF SAN ANTONIO
   HAS BECOME UNDERCUT BY SURGING COLD POOL MIGRATING SWD INTO SCNTRL
   TX.  ANOTHER SEWD MOVING COLD POOL WAS APPROACHING KLRD WITH TSTMS
   TRYING TO INITIATE ALONG IT.  12 UTC KBRO/KCRP SOUNDINGS SUGGEST A
   SUBSTANTIAL CAP TO A SURFACE BASED PARCEL AND THIS MAY PARTIALLY
   EXPLAIN WHY CONVECTION IS HAVING A TOUGH TIME BECOMING ESTABLISHED
   SOUTH OF THE LATITUDE OF KCOT. 
   
   AS THE BOUNDARIES CONTINUE TO SAG SWD/SEWD AND THE BOUNDARY LAYER
   GRADUALLY WARMS THROUGH THE MORNING...MORE TSTMS COULD DEVELOP
   ACROSS THE WW. STEEP MIDLEVEL LAPSE RATES AND FAVORABLY MOIST
   ENVIRONMENT WILL BE CONDUCIVE TO LARGE HAIL...DAMAGING WINDS AND
   HEAVY RAINFALL.
