   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   70...71...CONTINUES.
   
   SUMMARY...GUSTY WINDS AND HAIL WILL BE NOTED ALONG SQUALL LINE AS IT
   SPREADS SEWD ACROSS THE ARKLATEX.
   
   DISCUSSION...ONGOING SQUALL LINE THAT STRETCHES FROM SRN AR...SWWD
   INTO NERN TX IS PROPAGATING SEWD AT ROUGHLY 30-35KT.  GIVEN THE SLOW
   AIRMASS RECOVERY ACROSS NRN LA IT APPEARS THIS CONVECTION SHOULD BE
   MAINTAINED AS IT SPREADS ACROSS INSTABILITY AXIS CHARACTERIZED BY
   MUCAPE OF 1000-1500 J/KG.  LATEST WDSS MESH DATA SUGGESTS EMBEDDED
   HAIL CORES ARE MOSTLY LESS THAN ONE INCH ALTHOUGH OCCASIONALLY
   SPIKING TO SEVERE LEVELS AT TIMES.  OTHERWISE...ISOLATED SEVERE WIND
   GUSTS CAN BE EXPECTED WITH THIS LINEAR MCS AS IT MOVES SEWD.
