   MESOSCALE DISCUSSION 1254
   NWS STORM PREDICTION CENTER NORMAN OK
   0351 PM CDT TUE JUN 30 2015

   AREAS AFFECTED...PORTIONS OF FL/GA

   CONCERNING...SEVERE THUNDERSTORM WATCH 375...376...

   VALID 302051Z - 302245Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   375...376...CONTINUES.

   SUMMARY...THE RISK FOR SVR TSTMS CONTINUES ACROSS PORTIONS OF THE
   SEVERE THUNDERSTORM WATCH AREAS.

   DISCUSSION...A FORWARD-PROPAGATING CONVECTIVE CLUSTER IS ADVANCING
   EWD ACROSS PORTIONS OF THE FL PANHANDLE AND SRN AL/GA AND WILL
   CONTINUE SPREADING ACROSS PARTS OF NRN FL AND SRN GA. IN AREAS WHERE
   ANTECEDENT CONVECTIVE PROCESSING HAS NOT BEEN ABUNDANT
   DOWNSTREAM...THE RISK FOR DMGG WIND GUSTS MAY ACCOMPANY THIS
   ACTIVITY AS CONTINUES TRACKING EWD. AN OUTFLOW BOUNDARY OVER THE NRN
   FL PENINSULA EXTENDS WWD ACROSS PARTS OF THE SRN FL PANHANDLE...AND
   LOCATIONS NEAR/S OF THIS BOUNDARY SHOULD EXPERIENCE THE GREATEST SVR
   RISK WHERE INSTABILITY IS MODERATE TO STRONG. WW 376 MAY NEED TO BE
   LOCALLY EXTENDED EWD ACROSS PARTS OF THE SRN FL PANHANDLE IF
   CONFIDENCE WERE TO INCREASE THAT CONVECTION WOULD BE SUSTAINED EWD
   NEAR/S OF THE BOUNDARY.
