   MESOSCALE DISCUSSION 0353
   NWS STORM PREDICTION CENTER NORMAN OK
   0336 PM CDT MON APR 14 2014

   AREAS AFFECTED...SERN LA...SRN MS AND AL...WRN FL PANHANDLE

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 142036Z - 142300Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...STORMS ARE EXPECTED TO GRADUALLY DEVELOP NEWD OUT OF SERN
   LA...WITH SOME CONDITIONAL THREAT OF BRIEF TORNADOES.

   DISCUSSION...A CLUSTER OF STORMS HAS FORMED OVER SERN LA...IN A
   REGION WHERE RICHER LOW LEVEL MOISTURE HAS MOVED INLAND AND WHERE
   HEATING HAS DESTABILIZED THE AREA. ALSO IN THIS GENERAL VICINITY IS
   AN OUTFLOW BOUNDARY...CURRENTLY EXTENDING FROM SWRN MS INTO SERN LA
   TO JUST OFF THE MS/AL COASTS.

   AS THE UPPER TROUGH APPROACHES...INCREASING WIND PROFILES WILL HELP
   TO PUSH THE OLD OUTFLOW BOUNDARY FARTHER INLAND...AND WILL ALSO
   RESULT IN INCREASED SRH LEVELS. ALTHOUGH THERE MAY BE NUMEROUS
   STORMS...ESPECIALLY AS THE COLD FRONT APPROACHES...A FEW STORMS MAY
   ACQUIRE ROTATION AND A TORNADO CANNOT BE RULED OUT. TRENDS WILL BE
   MONITORED FOR A POTENTIAL TORNADO WATCH LATER THIS
   AFTERNOON/EVENING.
