   MESOSCALE DISCUSSION 0354
   NWS STORM PREDICTION CENTER NORMAN OK
   0700 PM CDT MON APR 14 2014

   AREAS AFFECTED...CENTRAL GULF COAST

   CONCERNING...SEVERE THUNDERSTORM WATCH 81...

   VALID 150000Z - 150100Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 81
   CONTINUES.

   SUMMARY...ISOLATED SEVERE THREAT CONTINUES ALONG THE CENTRAL GULF
   COAST.  NEW WW MAY BE CONSIDERED ALONG THE CNTRL GULF COAST IF
   CONVECTIVE TRENDS INCREASE WITHIN FAVORABLE AIR MASS.

   DISCUSSION...OUTFLOW FROM EARLIER CONVECTION HAS PROGRESSED OFFSHORE
   ALONG THE MS/AL COAST.  WITH AN EXPANSIVE AREA OF PRECIPITATION NOW
   NOTED ACROSS INTERIOR MS/SRN AL THERE IS LITTLE REASON TO BELIEVE
   THIS BOUNDARY WILL RETURN APPRECIABLY NWD...AT LEAST WEST OF THE FL
   PANHANDLE.  DOWNSTREAM...MARITIME TROPICAL AIR MASS WILL GRADUALLY
   ADVANCE NWD ACROSS THE FL PANHANDLE WITH NEAR 70 SFC DEW POINTS
   EXPECTED TO SPREAD SLOWLY NWD AHEAD OF APPROACHING MCS.  AT TIMES
   VARIOUS SHEAR COUPLETS HAVE FORMED IN ASSOCIATION WITH SMALL
   SUPERCELLS OFFSHORE BUT UPDRAFTS HAVE STRUGGLED TO MAINTAIN THEIR
   STRUCTURES AS THEY LIFT NORTH OF THE BARRIER ISLANDS.  WILL CONTINUE
   TO MONITOR THERMODYNAMIC CHANGES ALONG THE COAST AND UNTIL MORE
   BUOYANT AIR MASS CAN SPREAD INLAND SEVERE THREAT SHOULD REMAIN
   ISOLATED.
