   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 309 CONTINUES.
   
   THE SEVERE THREAT ACROSS ERN NC WILL BECOME INCREASINGLY MARGINAL
   OVER THE NEXT 1 TO 2 HOURS. WW 310 AND WW 309 WILL BE ALLOWED TO
   EXPIRE AT 03Z.
   
   A CONVECTIVE CLUSTER ONGOING IN ERN NC WILL CONTINUE TO MOVE EWD
   INTO THE PAMLICO SOUND LATE THIS EVENING. RUC DATA AND REGIONAL
   FORECAST SOUNDINGS ACROSS THIS AREA SHOW WEAK INSTABILITY WITH
   STRONG VERTICAL SHEAR AND STEEP MID-LEVEL LAPSE RATES. THIS
   ENVIRONMENT MAY CONTINUE TO SUPPORT A THREAT FOR HAIL AND ISOLATED
   WIND DAMAGE OVER THE NEXT HOUR. HOWEVER...INSTABILITY WILL CONTINUE
   TO WEAKEN AND THIS SHOULD ALLOW THE SEVERE THREAT TO BECOME
   INCREASINGLY MARGINAL.
