AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
341 PM CDT THU AUG 12 2010
.SHORT TERM...
DISORGANIZED REMNANTS OF TD 5 ARE CONTINUING TO IMPACT PORTIONS OF
SOUTHEAST LOUISIANA AND SOUTHERN MISSISSIPPI. RADAR/SATELLITE
LOOPS INDICATE THAT THE EARLIER LOW PRESSURE CIRCULATION IS
LARGELY UNAPPARENT...ALTHOUGH IT APPEARS THAT SOME SORT OF
WEAK CIRCULATION HAS REFORMED SLIGHTLY TO THE EAST DIRECTLY SOUTH
OF COASTAL MISSISSIPPI. CONVECTION IS LARGELY CONFINED TO WEST
SIDE OF THE LOW...WHICH IS KEEPING PORTIONS OF FAR SOUTHEAST
LOUISIANA...INCLUDING THE NEW ORLEANS METRO AREA...IN THE
IMMEDIATE HEAVY RAIN THREAT. ACROSS THE REMAINDER OF THE
AREA...CONVECTION HAS BEEN SLOW TO DEVELOP AROUND THE BATON ROUGE
AND MCCOMB AREAS...BUT SCATTERED DIURNAL CONVECTION IS BEGINNING
TO SHOW ITSELF IN THESE AREAS.
THE LOW ITSELF SHOULD BEGIN TO MOVE SLOWLY TO THE NORTHWEST
THROUGH THE NIGHT AND INTO FRIDAY...WITH PERIODS OF HEAVY RAIN
CONTINUING. GREATEST HEAVY RAIN IMPACT STILL LOOKS TO BE ACROSS
FAR SOUTHEAST LOUISIANA...PARISHES ALONG THE GULF COAST...AND
COASTAL MISSISSIPPI. HOWEVER...MORE ISOLATED BOUTS OF MODERATE TO
HEAVY RAIN COULD OCCUR ACROSS THE REMAINDER OF THE FORECAST AREA.
WILL LEAVE THE ORIENTATION AND DURATION OF THE FLASH FLOOD WATCH
AS IS FOR NOW...WITH ENOUGH UNCERTAINTY REMAINING AS TO HOW LONG
THE LOW WILL REMAIN IN THE AREA.
FROM FRIDAY NIGHT ON...THE PRECIPITATION COVERAGE WILL LIKELY
BEGIN TO DECREASE...WITH THINGS RETURNING TO MORE OF A DIURNAL
THUNDERSTORM CYCLE. KAH
.LONG TERM...
UNCERTAINTY ABOUNDS IN THE EXTENDED...WITH THE GFS AND ECMWF BOTH
WANTING TO CURVE TD 5/S REMNANTS ACROSS THE SOUTHEASTERN CONUS AND
BACK OUT INTO THE GULF. A FRONTAL BOUNDARY WILL ALSO MOVE INTO THE
REGION LATE IN THE WEEKEND AND EARLY NEXT WEEK. STILL SOMEWHAT
SKEPTICAL ABOUT THE GFS AND ECMWF SOLUTIONS...BUT WILL CONTINUE TO
CARRY HIGHER DAYTIME POPS THROUGHOUT MUCH OF THE EXTENDED...WITH
THINGS DRYING OUT MARGINALLY TOWARD LATE NEXT WEEK. TEMPERATURES
WILL LARGELY BE NEAR TO ABOVE NORMAL THROUGHOUT THE EXTENDED. KAH
&&
.AVIATION...
AN AREA OF LOW PRESSURE...THE REMNANTS OF TROPICAL DEPRESSION
5...WILL CONTINUE TO MOVE SLOWLY INLAND OVER SOUTHEAST LOUISIANA
THROUGH FRIDAY. WINDS ACROSS THE AREA WILL REMAIN RATHER LIGHT...10
KNOTS OR LESS...BUT DIRECTIONS WILL VARY BASED ON THE LOCATION OF
THE LOW. WINDS WILL GRADUALLY BECOME MORE WESTERLY EARLY FRIDAY AS
THE LOW MOVES INLAND AND OPENS. BKN/OVC MID-HIGH CLOUD DECKS WILL
PREVAIL THROUGH THE PERIOD BUT OCCASIONAL MVFR CIGS/VISBYS
ASSOCIATED WITH SHOWERS OR THUNDERSTORMS WILL BE POSSIBLE. 87
&&
.MARINE...
THE REMNANT LOW FROM WHAT WAS TROPICAL DEPRESSION FIVE WILL CONTINUE
TO MOVE INLAND OVER SOUTHEAST LOUISIANA THROUGH TONIGHT. SCATTERED
TO NUMEROUS SHOWERS AND THUNDERSTORMS CAN BE EXPECTED ALONG WITH
MODERATE WINDS AND MODERATE TO HIGH SEAS. WINDS OVER THE COASTAL
WATERS WEST OF THE SOUTHWEST PASS OF THE MISSISSIPPI RIVER WILL BE
OUT OF THE WEST TO SOUTHWEST WHILE EAST OF THIS POINT WINDS WILL BE
MORE SOUTHERLY. WIND SPEEDS WILL CONTINUE TO RUN FROM 15 TO 20 KNOTS
THROUGH FRIDAY WITH SEAS EXPECTED TO REMAIN BETWEEN 4 TO 6 FEET.
BECAUSE OF THIS...SMALL CRAFT EXERCISE CAUTION HEADLINES WILL
CONTINUE OVER PORTIONS OF THE COASTAL WATERS THROUGH FRIDAY. WINDS
AND SEAS WILL SUBSIDE OVER THE WEEKEND AS HIGH PRESSURE BEGINS TO
BUILD OVER THE AREA. 87
