   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 130...131...CONTINUES.
   
   SUMMARY...PRIMARY THREAT HAS LARGELY TRANSITIONED TO SCATTERED
   DAMAGING WINDS WITH SECONDARY THREATS FOR MARGINAL HAIL/TORNADO
   ALONG AN EXTENSIVE QLCS CROSSING THE PIEDMONT INTO THE
   MID/SOUTH-ATLANTIC COASTAL PLAIN.
   
   DISCUSSION...MOST INTENSE PORTION OF AN ELONGATED QLCS STRETCHED
   FROM 30 SW OF DCA THROUGH THE RALEIGH-DURHAM METRO AREA AND ON S TO
   SRN SC. A COUPLE OF BOWING SEGMENTS WERE EVIDENT ALONG THE LINE AND
   SHOULD SERVE TO ENHANCE RISKS FOR SWATHS OF DAMAGING WINDS IN THE
   NEAR-TERM. MEANWHILE...DISCRETE SUPERCELLS INVOF RICHMOND AREA HAVE
   GRADUALLY BECOME ABSORBED INTO THE SURGING PORTION OF THE QLCS. AS
   SUCH...OVERALL SEVERE RISK APPEARS TO HAVE TRANSITIONED TO PRIMARILY
   DAMAGING WINDS. MOST OF THIS LINE WILL PROGRESS INTO WW 134 BY 01Z.
