MESOSCALE DISCUSSION 0214
   NWS STORM PREDICTION CENTER NORMAN OK
   1157 PM CST SUN FEB 24 2013
   
   AREAS AFFECTED...COASTAL PORTIONS OF LA/MS/AL
   
   CONCERNING...SEVERE POTENTIAL...WATCH NEEDED SOON 
   
   VALID 250557Z - 250700Z
   
   PROBABILITY OF WATCH ISSUANCE...95 PERCENT
   
   SUMMARY...BOUTS OF LARGE HAIL AND PERIODIC WIND DAMAGE WILL BE
   POSSIBLE OVERNIGHT ACROSS COASTAL PORTIONS OF LA/MS/AL. MORE OF A
   SURFACE BASED SEVERE RISK INCLUDING SOME TORNADO POTENTIAL COULD
   INCREASE THROUGH THE EARLY MORNING HOURS. A SEVERE TSTM WATCH WILL
   LIKELY BE ISSUED SHORTLY FOR AT LEAST MUCH OF SOUTHEAST LA.
   
   DISCUSSION...BANDS OF ELEVATED TSTMS HAVE BEEN PERSISTENT THIS
   EVENING/EARLY IN THE OVERNIGHT TO THE NORTH OF A WARM FRONT THAT
   CONTINUES TO SLOWLY SPREAD NORTHWARD TOWARD THE COAST. AS SAMPLED BY
   THE EARLIER 00Z OBSERVED SOUNDINGS FROM LAKE CHARLES/SLIDELL
   LA...RELATIVELY STEEP LAPSE RATES/MODERATE MUCAPE CONTINUES TO
   REMAIN FAVORABLE FOR BOUTS OF LARGE HAIL...ESPECIALLY WITH EMBEDDED
   SUPERCELLS ACROSS SOUTHEAST LA ON THE SOUTHERN FLANK OF INLAND
   PRECIPITATION. DAMAGING WINDS COULD BECOME A BIT MORE OF A CONCERN
   AS WELL...ALONG WITH SOME TORNADO RISK...AS A WARM FRONT SLOWLY
   MOVES NORTHWARD/INLAND THROUGH THE EARLY MORNING HOURS.
