   CONCERNING...SEVERE THUNDERSTORM WATCH 243...
   
   VALID 050108Z - 050245Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 243
   CONTINUES.
   
   BOW ECHO OVER SERN NC WAS MOVING NEWD AT 40 KTS AND WILL PASS THE
   I-40 CORRIDOR TO AREAS SOUTH OF GOLDSBORO AND KINSTON AND NEAR
   JACKSONVILLE THROUGH 0130Z.  STORMS APPEAR TO BE WEAKENING...BUT
   DMGG WIND GUSTS MAY STILL OCCUR UNTIL COLD POOL DYNAMICS WEAKEN. 
   AIR MASS DOWNSTREAM...GENERALLY NE OF ROUTE 70...WAS IMPACTED BY
   EARLY DAY CONVECTION AND IS LIKELY COMPARATIVELY LESS UNSTABLE.
   
   MEANWHILE...WIDESPREAD CONVECTION CONTINUES UPSTREAM ACROSS THE SC
   MIDLANDS WITH EMBEDDED BOWISH TYPE STRUCTURES.  THIS ACTIVITY WAS
   ASSOCIATED WITH A DEVELOPING MCV AND MAY ALSO POSE AT LEAST AN ISOLD
   DMGG WIND OR BRIEF TORNADO THREAT FOR A COUPLE MORE HOURS.  BUT
   NOCTURNAL COOLING SHOULD MARK A WEAKENING TREND THROUGH MID-
   EVENING.
   
   FINALLY...TSTMS HAVE BEEN DEVELOPING INVOF THE CDFNT ALONG THE VA/NC
   BORDER.  UPDRAFTS APPEAR TO BE GETTING UNDERCUT BY THE SURGING
   FRONT...BUT NOT LIKELY ELEVATED ENOUGH TO COMPLETELY RULE OUT A DMGG
   WIND GUST OR BRIEF TORNADO AS THEY MOVE FROM THE I-85 CORRIDOR EWD
   TOWARD EMPORIA/I-95 THROUGH MID-EVENING.
