   MESOSCALE DISCUSSION 0192
   NWS STORM PREDICTION CENTER NORMAN OK
   1027 AM CDT SUN MAR 16 2014

   AREAS AFFECTED...EXTREME SERN AL...THE WRN AND CNTRL FL PANHANDLE
   AND SWRN GA

   CONCERNING...TORNADO WATCH 30...31...

   VALID 161527Z - 161700Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 30...31...CONTINUES.

   SUMMARY...THE THREAT FOR DAMAGING WIND AND BRIEF ISOLATED TORNADOES
   SHOULD PERSIST NEXT FEW HOURS FROM THE CNTRL FL PANHANDLE...EXTREME
   SERN AL INTO SWRN GA.

   DISCUSSION...LATE THIS MORNING A NE-SW ORIENTED LINE OF STORMS FROM
   SERN AL SWWD INTO THE WRN FL PANHANDLE WAS MOVING EAST AT 35 KT.
   STORMS WITH MESO-VORTEX CIRCULATION ALONG NRN END OF THE LINE HAVE
   WEAKENED SOMEWHAT AS THEY MOVE INTO A MORE STABLE BOUNDARY LAYER.
   NEVERTHELESS...THESE STORMS MAY REMAIN CAPABLE OF PRODUCING ISOLATED
   DAMAGING WIND AND A BRIEF TORNADO AS THEY CONTINUE EAST. VERY
   LIMITED INSTABILITY EXISTS DOWNSTREAM FROM THE CURRENT ACTIVITY.
   HOWEVER...A STRONG EWD MIGRATING SWLY LLJ IS ADVECTING LOW-60S
   DEWPOINTS RAPIDLY NEWD THROUGH THE PRE-CONVECTIVE WARM
   SECTOR...RESULTING IN RAPID BOUNDARY LAYER RECOVERY. THIS SUGGEST
   THE STORMS SHOULD PERSIST NEXT FEW HOURS WITHIN A LOW CAPE/HIGH
   SHEAR ENVIRONMENT. LATEST VWP DATA SHOW VERY LARGE 0-2 KM HODOGRAPHS
   AS WELL AS 50 KT DEEP LAYER SHEAR WHICH WILL CONTINUE TO SUPPORT
   EMBEDDED ORGANIZED STRUCTURES WITHIN THE LINE.
