   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 375
   CONTINUES.
   
   IN ADDITION TO LOCALLY EXCESSIVE RAINFALL...SOME THREAT FOR DAMAGING
   WIND GUSTS AND HAIL CONTINUES ACROSS WW AREA.
   
   CONTINUOUS TSTM REGENERATION HAS OCCURRED OVER THE METROPLEX TODAY
   DRIVEN LARGELY BY WAA ATOP EXPANDING COLD POOL.  THUS FAR...MCS COLD
   POOL HAS OVERWHELMED AMBIENT LOW-LEVEL SHEAR...RESULTING IN A
   CONSIDERABLE DISPLACEMENT OF A WARMER/MORE UNSTABLE BOUNDARY LAYER
   FROM ACTIVE TSTMS.  CURRENT VWP FROM FTW INDICATES SOME REMNANT OF
   NOCTURNAL LLJ ABOVE STRONGER OUTFLOW WINDS /OBSERVED BELOW 1 KM AGL/
   WHICH IS LIKELY DRIVING MORE INTENSE STORMS LOCATED OVER DALLAS...
   ELLIS AND KAUFMAN COUNTIES AS OF 1755Z.
   
   IT REMAINS UNCERTAIN AS TO WHETHER ONGOING STORMS WILL FURTHER
   ORGANIZE THIS AFTERNOON.  THE PRIMARY LIMITING FACTOR HAS BEEN THE
   PERSISTENT STRATUS/STRATO-CUMULUS DEVELOPMENT ON COOL SIDE OF
   CONVECTIVE OUTFLOW WHICH HAS LIMITED HEATING AND AIR MASS
   DESTABILIZATION.
