   MESOSCALE DISCUSSION 0011
   NWS STORM PREDICTION CENTER NORMAN OK
   0528 AM CST SAT JAN 09 2016

   AREAS AFFECTED...SOUTHEAST LOUISIANA

   CONCERNING...SEVERE THUNDERSTORM WATCH 2...

   VALID 091128Z - 091230Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 2 CONTINUES.

   SUMMARY...A LIMITED SEVERE WEATHER THREAT ACROSS THE REMAINING VALID
   PORTION OF SEVERE TSTM WATCH 2 IN SOUTHEAST LA AND EAST ACROSS FAR
   SOUTHEAST LA /THROUGH PLAQUEMINES PARISH/ SUGGESTS THIS WATCH SHOULD
   EXPIRE AT 12Z.

   DISCUSSION...TRENDS IN EARLY MORNING SURFACE OBSERVATIONS INDICATED
   THE WARM FRONT HAS REMAINED OFFSHORE TERREBONNE AND LAFOURCHE
   PARISHES...WHILE CONTINUING TO EXTEND THROUGH SOUTHEAST PLAQUEMINES
   PARISH /NEAR OR MORE LIKELY SOUTHEAST OF KBVE/.  MOSAIC RADAR
   IMAGERY INDICATED AN EXTENSIVE AREA OF PRECIPITATION HAS SPREAD
   ACROSS MUCH OF SOUTHEAST LA...AHEAD OF THE PRIMARY BAND OF
   TSTMS...WHICH AT 1115Z EXTENDED FROM ST. CHARLES TO TERREBONNE
   PARISHES AND INTO THE NORTHWEST GULF OF MEXICO.  A COUPLE OF STORMS
   OFFSHORE NEAR AND AHEAD OF THE PRIMARY BAND...AND AT LEAST ONE STORM
   INLAND HAVE HAD ROTATION...THOUGH THE OFFSHORE STORMS HAVE THE
   GREATEST TORNADO POTENTIAL...SINCE THE INLAND STORMS ARE ELEVATED. 
   THE EXTENSIVE AREA OF PRECIPITATION WILL CONTINUE TO SPREAD ACROSS
   SOUTHEAST LA THIS MORNING...PRECEDING THE RELATIVELY STRONGER
   STORMS...AND SHOULD LIMIT DESTABILIZATION.  THIS FACTOR AND THE
   SMALL AREAL COVERAGE REMAINING FOR ANY ADDITIONAL SEVERE-WEATHER
   THREAT APPEARS TO PRECLUDE THE NEED FOR ADDITIONAL WATCHES IN
   SOUTHEAST LA.
