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.
