Damaging Wind in Louisiana, June 13, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
1009 AM CDT FRI JUN 13 2003

OLD OUTFLOW BOUNDARY ANALYZED JUST SOUTH OF JASPER AND FORT POLK.
VISIBLE IMAGERY SHOWING TSTM COMPLEX UPSTREAM OVER NE TX AND NW LA
ALREADY PUTTING OUT NEW OUTFLOWS NORTH OF THE FORECAST AREA AND
ANOTHER STRONG SEABREEZE IS EVIDENT...ALREADY ACROSS I-10.

WAS GOING TO GO WITH A 50 PERCENT POP FOR NRN ZONES BASED ON EXISTING
MOISTURE AND INSTABILITY...BUT WILL RAISE POPS TO 70 PERCENT AS
THOSE BOUNDARIES COLLISION LOOKS INEVITABLE...SIMILAR TO YESTERDAY.
DEVELOPMENT MAY BE DELAYED BY A WEAK CAP HOWEVER CAP SHOULD BE
MIXED OUT BY MID-DAY. CAPES NOT AS STRONG AS YESTERDAY BUT STILL
RESPECTABLE...GREATER THAN 2000J. WILL TWEAK TEMPS DOWN A BIT FOR
THE STRONGER SEABREEZE AND EXPECTED CLOUD-COVER BY THIS AFTERNOON.

...PREVIOUS DISCUSSION...
CURRENTLY...REMNANTS OF AN MCS ARE NOW LOCATED FROM ST MARTIN PARISH
DOWN THROUGH THE COASTAL WATERS. TSTMS ARE MOSTLY CONCENTRATED
OFFSHORE AND CONTINUE TO PUSH SOUTHEAST. ANOTHER AREA OF TSTMS
DEVELOPED NORTH OF TYLER, TX AND IS MOVING ESE INTO THE SHREVEPORT
AREA. THIS AREA MAY CLIP OUR NORTHERN PARISHES BUT APPEARS TO BE
WEAKENING AS IT MOVES EAST.

THE MESO-ETA DEPICTS AN MCS FORMING IN NORTH-CENTRAL TX AND MOVES IT
IN A PRETTY MUCH SOUTH-SOUTHEASTERLY DIRECTION. THE GFS MISSED THE
EARLIER MCS COMPLETELY...BUT DOES DEPICT SOME OF THE ACTIVITY NOW
OCCURRING IN N TX. THIS AREA APPEARS TO BE OUR NEXT SHOT OF RAIN
TODAY. BOTH MODELS AGREE ON BRINGING A BROAD TROF INTO CENTRAL TX BY
SUNDAY MORNING. THE GFS KEEPS AN UPPER LEVEL LOW PRETTY MUCH
STATIONARY IN NE TX THROUGH THE EXTENDED...KEEPING THE CHANCE OF RAIN
IN OUR FCST THROUGHOUT THE PERIOD WITH THE BEST ENERGY BEING TO THE
NORTH OF US AROUND THE LOW ITSELF.

SO FOR THE SHORT TERM...WILL KEEP CHANCE POPS IN THE FCST TODAY...A
LITTLE HIGHER IN THE LFT AREA AS CURRENT ACTIVITY COMBINED WITH WHAT
MAKES IT DOWN HERE FROM N TX WILL LINGER IN LFT A BIT LONGER.

SATURDAY MORNING STILL LOOKS LIKE THE BEST CHANCE FOR TSTMS IN THE
NEXT FEW DAYS AS MESO-ETA HAS BEEN CONSISTENTLY DEPICTING ANOTHER MCS
FORMING IN NE TX AND MOVING DOWN THIS WAY. SPC HAS SLGT RISK TO OUR
WEST UNTIL SATURDAY MORNING AFTER WHICH ALL OF OUR CWA IS INCLUDED IN
SLGT RISK.

WILL CONTINUE THE CHANCE POPS DAY/SLGT CHANCE NIGHT THROUGH THE END
OF THE PERIOD...GOING WITH HALF CONSISTENCY AND HALF BELIEF IN GFS.
