   MESOSCALE DISCUSSION 0310
   NWS STORM PREDICTION CENTER NORMAN OK
   1004 AM CDT MON APR 07 2014

   AREAS AFFECTED...SERN AL/FL PANHANDLE/PARTS OF SRN AND CENTRAL GA
   INTO SRN AND ERN SC AND N FL

   CONCERNING...TORNADO WATCH 67...

   VALID 071504Z - 071700Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 67 CONTINUES.

   SUMMARY...BAND OF ORGANIZED STORMS CONTINUES MOVING EWD THROUGH WW
   67.  ISOLATED SEVERE/LOCAL TORNADO RISK CONTINUES WITH STRONGEST
   CONVECTIVE ELEMENTS WITHIN THE LARGER-SCALE BAND.

   DISCUSSION...MORNING WV IMAGERY CONTINUES TO DEPICT EXTENSIVE CLOUD
   COVER DOWNSTREAM OF ONGOING CONVECTIVE BAND...WHICH CONTINUES TO
   HINDER HEATING/DESTABILIZATION AHEAD OF THE STORMS.  THAT SAID...A
   MOIST/MARGINALLY UNSTABLE AIRMASS CURRENTLY IN PLACE REMAINS
   SUFFICIENT FOR SUSTAINING THE ORGANIZED BAND OF CONVECTION NOW
   CROSSING GA/SERN AL/THE FL PANHANDLE.

   ATTM...IT APPEARS THAT CONVECTION SHOULD REMAIN ROUGHLY STEADY-STATE
   IN TERMS OF INTENSITY/SEVERITY AS IT TRAVERSES WW 67 -- I.E. WITH
   ONLY OCCASIONAL STRONGER CELLS WITHIN THE LINE POSING ANY
   SEVERE/TORNADO RISK.  E OF THE EXISTING WATCH...AN INCREASINGLY
   MOIST BOUNDARY LAYER IS BEING ADVECTED ONSHORE OVER SERN GA AND
   ADJACENT SRN SC.  ASSOCIATED AIRMASS DESTABILIZATION MAY SUPPORT
   SOME INCREASE IN CONVECTIVE INTENSITY AS THE LINE OF STORMS MOVES
   TOWARD THE COAST LATER THIS MORNING -- POSSIBLY REQUIRING NEW WW
   ISSUANCE.
