   CONCERNING...SEVERE THUNDERSTORM WATCH 203...
   
   VALID 140239Z - 140415Z
   
   LARGE HAIL AND ISOLD DAMAGING WIND THREATS WILL CONTINUE ACROSS SRN
   PORTIONS OF CNTRL TX.
   
   OUTFLOW BOUNDARY CONTINUES TO RAPIDLY TRANSLATE SWWD INTO SWRN TX...
   HAVING MOVED WEST OF KMAF...THEN CURVING SEWD THROUGH ERN PECOS AND
   CROCKETT COUNTIES. LATEST MESOANALYSIS SHOWS THERMAL RIDGE NOSING
   NWD TO THE OUTFLOW BOUNDARY...WITH LOW LEVEL DEW POINTS SURGING WWD
   TOWARD THE BIG BEND AREA.  00 UTC KDRT SOUNDING SHOWED A FAIRLY
   SUBSTANTIAL CAP.  AS THE OUTFLOW BOUNDARY MOVES SWWD...IT SEEMS TO
   BE EFFECTIVE IN FORCING PARCELS THROUGH THE CAP...THOUGH UPDRAFTS
   ARE STRUGGLING ACROSS MENARD...SCHLEICHER AND ERN CROCKETT COUNTIES.
    THOUGH INTENSITY OF THE TSTMS HAS DECREASED SINCE 00 UTC...AREAS
   SOUTH/WEST OF JUNCTION HAVE REMAINED ESSENTIALLY FREE OF TSTMS
   TODAY...AND THE MUCAPE REMAINS AROUND 4000 J/KG.  GIVEN THE ONSET OF
   DIURNAL COOLING...TSTMS MAY BECOME MORE ELEVATED AS SLY FLOW
   DECOUPLES.  GIVEN MAGNITUDE OF POTENTIAL INSTABILITY...LARGE HAIL
   AND PERHAPS ISOLD DAMAGING WINDS MAY OCCUR WITH ANY TSTM.
