   VALID 282342Z - 010115Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 34
   CONTINUES.
   
   BAND OF STRONG TSTMS CONTINUES TO SHIFT EWD ACROSS THE PIEDMONT OF
   NC/SC AND NRN GA EARLY THIS EVENING.  THERE HAVE BEEN OCCASIONAL
   BOWING OF LINE SEGMENTS MOVING AROUND 50 KTS.  LATEST VWP FROM GSP
   INDICATES A DEEP UNIDIRECTIONAL WLY FLOW WITH 50 KTS 1.5-2KM AGL. 
   THIS IN COMBINATION WITH PCPN LOADING AND STORMS MOVING INTO AROUND
   25 DEGREE TEMP-DEW POINT DEPRESSIONS SUGGEST THAT DMGG WINDS WILL BE
   THE PRIMARY THREAT.  HOWEVER...WARM SECTOR WIND PROFILES STILL
   EXHIBIT CONSIDERABLE SPEED SHEAR WITH 0-1KM VALUES IN EXCESS OF 250
   M2/S2.  THUS...IT IS NOT OUT OF THE QUESTION THAT A BRIEF TORNADO
   COULD OCCUR...ESPECIALLY IF ANY LINE SEGMENT/EMBEDDED SUPERCELL CAN
   LATCH ONTO AN OUTFLOW BOUNDARY FROM COMPANION ACTIVITY TO IT/S NE. 
   THROUGH 0030Z...THE HIGHEST POTENTIAL FOR DMGG WINDS/ISOLATED
   TORNADO WILL OCCUR ACROSS THE MIDLANDS OF SC FROM GREENWOOD SC TO
   AREAS NEAR/NW OF COLUMBIA SC.
