   MESOSCALE DISCUSSION 1993
   NWS STORM PREDICTION CENTER NORMAN OK
   0402 AM CST WED DEC 24 2014

   AREAS AFFECTED...FL PANHANDLE/N FL AND ADJACENT SRN GA/FAR SERN SC

   CONCERNING...TORNADO WATCH 562...

   VALID 241002Z - 241200Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 562 CONTINUES.

   SUMMARY...LIMITED SEVERE/ISOLATED TORNADO RISK CONTINUES -- AND WILL
   PERSIST BEYOND THE SCHEDULED 24/12Z EXPIRATION OF WW 562 -- THUS
   LIKELY REQUIRING NEW WW ISSUANCE ACROSS THE CURRENT WW AREA AND TO
   THE E.

   DISCUSSION...LATEST RADAR TRENDS SUGGEST AN INCREASINGLY
   BANDED/LINEAR EVOLUTION TO THE CONVECTION ACROSS WRN PORTIONS OF WW
   562 -- I.E. FROM S CENTRAL GA SWWD INTO THE CENTRAL FL PANHANDLE. 
   AS THE SYNOPTIC STORM SYSTEM CONTINUES EWD...EXPECT LINEAR EVOLUTION
   TO CONTINUE ALONG/AHEAD OF THE ADVANCING COLD FRONT...WITH STRONGER
   EMBEDDED CELLS REMAINING CAPABLE OF LOCALLY GUSTY/DAMAGING WINDS AND
   A COUPLE OF TORNADOES.

   MEANWHILE...PERSISTENT SLY SURFACE WINDS ACROSS THE FL/S GA/SRN
   ATLANTIC COASTAL AREAS CONTINUE TO ERODE THE SRN FRINGE OF THE
   DAMMING AIRMASS...WITH UPPER 60S TO NEAR 70 DEWPOINTS NOW IN PLACE
   ACROSS SERN GA AND NOSING INTO FAR SERN SC.  THOUGH THE MAIN FOCUS
   FOR STRONGER STORMS WILL REMAIN INVOF THE ADVANCING COLD
   FRONT...LIMITED SHORTER-TERM RISK FOR ISOLATED/ROTATING CELLS HAS
   INCREASED ACROSS SERN GA AND SERN SC.

   EVENTUALLY...GREATER SEVERE RISK ASSOCIATED WITH THE MAIN CONVECTIVE
   BAND WILL SPREAD INTO THIS REGION AS WELL -- I.E. E OF THE CURRENT
   WW 562.  THEREFORE...WITH WW 562 SCHEDULED TO EXPIRE AT 24/12Z...NEW
   WW ISSUANCE WILL LIKELY BE REQUIRED -- AND WILL EXTEND EWD TO THE
   SERN SC/GA COAST.
