AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
707 AM CDT SAT SEP 3 2011

...TROPICAL STORM LEE HEADING TOWARD THE SOUTH CENTRAL LOUISIANA
COAST...

.DISCUSSION...
OBVIOUS PRIMARY SHORT TERM CONCERN...THE NEXT 48 HRS OR SO...IS
TROPICAL STORM LEE. LATEST ADVISORY FROM NHC PLACES THE CENTER ABOUT
95 MILES S OF LAFAYETTE...HEADING NNW AT 7 MPH...WITH MAX WINDS
AROUND 50 MPH. LATE NIGHT AIRCRAFT FIXES...AND OVERNIGHT
SATELLITE/RADAR IMAGERY INDICATE THE CENTER HAS BEEN
WOBBLING/REFORMING TO THE NORTHWEST. THIS HAS RESULTED IN A WWD
SHIFT OF THE FORECAST TRACK...WHICH NOW CALLS FOR LANDFALL ALONG THE
IBERIA PARISH COAST DUE SOUTH OF NEW IBERIA LATER THIS AFTERNOON OR
EVENING. FROM A PRACTICAL STANDPOINT...THIS SUBTLE SHIFT IN THE
TRACK WILL END UP MEANING LITTLE...AS LEE CONTINUES TO BE A VERY
ASYMMETRIC AND SOMEWHAT BROAD STORM...WITH THE BULK OF THE STRONG
WINDS/RAINFALL DISPLACED TO THE NORTH/EAST OF THE CENTER.

ALTHOUGH CONVECTION PERIODICALLY ATTEMPTS TO WRAP COMPLETELY AROUND
THE CENTER...THE INFLUX OF DRY AIR FROM THE WEST...AND WIND SHEAR
COURTESY OF AN UPPER TROF OVER THE NW GULF...HAVE THUS FAR PREVENTED
THIS FROM BEING SUCCESSFUL TO ANY SIGNIFICANT DEGREE. STILL...LEE
HAS MANAGED TO CONTINUE SLOWLY STRENGTHENING...AND WIND GUSTS IN
EXCESS OF 40 KNOTS ARE BEING REPORTED AT NUMEROUS OIL PLATFORMS OFF
THE SOUTHWEST AND SOUTH CENTRAL LOUISIANA COAST...WITH A LARGE
PRECIPITATION SHIELD COVERING THE EASTERN THIRD TO HALF OF THE
FORECAST AREA.

THE GREATEST HAZARDS ASSOCIATED WITH LEE CONTINUE TO A PROLONGED
PERIOD OF TROPICAL STORM FORCE WINDS...AND INLAND FLOODING DUE TO
THE SLOW FORECAST MOVEMENT. A FLASH FLOOD WATCH WAS ISSUED YESTERDAY
FOR PARTS OF SOUTH CENTRAL LOUISIANA...AND THIS STILL LOOKS GOOD.
HEAVIER RAINFALL RATES THUS FAR HAVE BEEN BETWEEN ONE HALF TO THREE
QUARTERS OF AN INCH PER HOUR...BUT THIS EVENT WILL BE MORE OF A
MARATHON THAN A SPRINT...WITH TOTAL RAINFALL ACCUMULATIONS OF 5 TO
10 INCHES...WITH LOCALLY HIGHER AMOUNTS...POSSIBLE IN THE WARNED
AREA. THE WATCH MAY NEED TO BE EXPANDED WWD AND NWD SLIGHTLY PENDING
RAINFALL EVOLUTION TODAY AND SUBSEQUENT LEE FORECASTS FROM NHC.

AS LEE BEGINS TO ACCELERATE TO THE NORTHEAST AWAY FROM THE AREA
SUNDAY NIGHT...THE UPPER TROUGH RESPONSIBLE FOR THIS WILL SEND A
STRONG EARLY FALL COLD FRONT THROUGH THE REGION. MUCH DRIER AND
COOLER AIR IS PROGGED TO FILTER IN BEHIND THE FRONT...WITH DEWPOINTS
DROPPING INTO THE 40S AND 50S. DAYTIME HIGHS MIDWEEK ARE EXPECTED TO
REACH THE LOWER/MID 80S...WITH MORNING LOWS IN THE UPPER 50S TO
LOWER 60S.

.MARINE...
TROPICAL STORM LEE NEAR 28.8N 91.9W AT 4 AM CDT DRIFTING TO THE
NORTH AROUND 7 MPH. ALL INTEREST SHOULD CONTINUE TO MONITOR THE
LATEST ADVISORIES FROM THE NATIONAL HURRICANE CENTER.
