AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
352 AM CDT TUE JUL 6 2010

.SHORT TERM... / TODAY THROUGH FRIDAY /
TODAYS WEATHER WILL BE DOMINATED BY NON TROPICAL LOW WHICH SEEMS
TO BE MOVING WESTWARD ALONG THE CENTRAL COAST. NUMEROUS SHOWERS
AND A FEW THUNDERSTORMS...SOME WITH HEAVY RAIN WILL REMAIN THE
MAIN THREAT TODAY. THE LOW IS EXPECTED TO MOVE INTO SOUTHEAST
TEXAS LATER TODAY. THERE WILL NOT BE MUCH OF A BREAK IN THE ACTION
AS MORE TROPICAL CONNECTION MOISTURE FROM THE CARIBBEAN WILL
STREAM NORTHWARD INTO LA AS A BROAD AREA OF LOW PRESSURE MOVES
INTO THE SOUTH CENTRAL GULF OF MEXICO LATER TODAY AND TONIGHT. THE
STRONG UPPER LEVEL RIDGE OVER THE MID ATLANTIC STATES IS EXPECTED
TO BUILD TOWARDS THE CENTRAL GULF COAST BY THURSDAY. THUS A RETURN
TO MORE NORMAL CONDITIONS ARE EXPECTED TOWARDS THE END OF THE WORK
WEEK.

&&

.LONG TERM... / SATURDAY THROUGH TUESDAY /
GENERAL TROFFING ALOFT IS EXPECTED TO PASS ACROSS THE CENTRAL AND
EASTERN SECTIONS OF THE COUNTRY ...WITH THE GEM MOST NOTABLE WITH
ITS AMPLITUDE AND TRYING TO DROP A COLD FRONT INTO THE GULF COAST
REGION. THE GFS AND EUROPEAN MODELS WERE NOT SO AMPLIFIED AND THIS
MAKES SENSE FOR THIS TIME OF YEAR.

WE WILL FOLLOW SOME SURFACE FRONTAL PATTERN STALLING WELL NORTH OF
OUR FORECAST AREA (FA) SATURDAY...AND THEN BECOME STATIONARY... OR
WASHING OUT.

CONVECTIVE ELEMENTS WERE GEARED WITH SLIGHTLY HIGHER VALUES SATURDAY
WHEN MODELS WERE IMPLYING DEEPER MOISTURE...THEN DROPPING OFF SUNDAY
AND INTO THE FIRST PART OF NEXT WEEK...AS HEIGHTS BEGIN TO RISE.

TEMPERATURES SHOULD BE CLOSE TO CLIMO FOR THIS TIME OF YEAR...AND
LITTLE QUIBBLE WITH GUIDE NUMBERS.

STUREY

&&

.AVIATION...
POTENT CIRCULATION ALONG THE CNTRL LOUISIANA COAST EARLY THIS
MORNING WILL MOVE INLAND (NORTH) TODAY. HOWEVER...A DEEP SELY
FLOW IS WELL ESTABLISHED FROM THE LOUISIANA LOW PRESSURE SYS
DOWN TO THE WRN CARRIBEAN. THE UPSHOT: PWATS CONTINUE TO INCREASE
WITH VALUES LIKELY RISING TO NEAR 2.5 INCHES THIS FORECAST CYCLE.
BANDS OF SHOWERS AND TSTMS WILL LIKELY CONTINUE DEVELOPING OVER THE
GULF AND MOVE ON-SHORE THIS MORNING. THEN WITH ADDITIONAL HEATING
OVER LAND TODAY...SHOWERS AND STORMS WITH TORRENTIAL RAINS LIKELY.
WE WOULD EXPECT AT LEAST WIDESPREAD MVFR CIGS IN THE CARDS...WITH
OCNL IFR CIGS/VSBYS IN SHOWERS AND STORMS.

MEANWHILE...LOOK FOR SURFACE WINDS TO GRADUALLY INCREASE...MAINLY
LATE IN THE PERIOD AT OUR TAF SITES...AND A BIT SLOWER THAN THE
FASTER MET GUIDE. GRADIENT FROM THE CARRIBEAN TROPICAL FEATURE AND
HIGH PRESSURE OFF TO THE NE WILL RESULT IN THIS NET INCREASE IN
WIND ACTION.

STUREY

&&

.MARINE...
WEAK LOW NEAR VERMILION BAY SHOULD CONTINUE TO MOVE WNW AND WEAKEN.
TROPICAL WAVE IN WRN CARIBBEAN FORECAST TO MOVE ACROSS THE YUCATAN
INTO THE SOUTHERN GULF TODAY. WIDELY VARYING SOLUTIONS AS TO
RESOLUTION OF THIS FEATURE. NAM SOLUTION DISCARDED...AS THIS WOULD
HAVE NEAR GALE FORCE WINDS IN OUR COASTAL WATERS BY MIDMORNING...AND
NO SIGNS OF WINDS OF THAT STRENGTH ANYWHERE IN GULF OR CARIBBEAN AT
THIS TIME. WINDS AND SEAS PATTERNED AFTER GFS WIND FIELD. NOTED THAT
ECMWF WINDS ARE ABOUT 5 TO 7 KNOTS LIGHTER...AS IT TAKES WAVE TOWARD
MEXICAN COAST. WILL HAVE SMALL CRAFT ADVISORIES OUTSIDE OF PROTECTED
WATERS BEGINNING THIS MORNING AND CONTINUING INTO WEDNESDAY. SEAS
WILL INCREASE TO 7 TO 9 FEET OVERNIGHT...MAINLY OFFSHORE...WITH
WINDS OF 20 TO 25 KNOTS. EXPECT CONDITIONS TO EASE FROM THE EAST
DURING THE DAYTIME HOURS WEDNESDAY...BUT ADVISORY MAY NEED TO BE
CONTINUED LONGER THAN IT CURRENTLY STANDS...MAINLY OVER OUR WESTERN
WATERS. 35
